Filler

In short: Fillers are biocompatible injections that restore facial volume loss and fill in static lines, with hyaluronic acid being the most common and calcium hydroxyapatite and poly-L-lactic acid being longer-acting alternatives. Duration of effect varies from 6 months to 2+ years depending on the product; Vascular occlusion is the most serious complication, but it can be treated by experienced physicians.

Description

Fillers (dermal fillers) are biocompatible materials injected under the skin or onto the muscle to restore the volume and elasticity that the face has lost due to time, gravity and sun damage. During the aging process, the deep structures of the face—bone, muscle, fat pads, and dermal collagen—gradually decrease (facial resorption). The result of this loss is sagging and depressions, which cause the "bones to collapse", the "cheeks to be hollow", and the "face to appear sunken and hanging". Filler injection "subtly" restores this volume loss, giving the face a "refreshed" and "rested" appearance.

Filler technology is built on two main paradigms: (1) immediate volume (instant volume provision) — at the time of injection, the filler material physically inflates that area, filler the line and creating a contour; (2) biostimulation (biostimulation) — some fillers (PLLA, PMMA) provide long-term benefits by stimulating the body's own collagen production. In today's clinical practice, the physician creates a "filler strategy" specific to each patient: which area, how much volume, which tissue plan (shallow vs. deep), which product (HA vs. CaHA vs. PLLA), which injection technique (needle vs. cannula, threading vs. bolus).

5 Main Filler Types and Family Taxonomy

1. Hyaluronic Acid (HA)

Hyaluronic acid is a neutralized polysaccharide naturally found in skin and joint fluid. It accounts for 80% of medical aesthetic fillers — brands like Juvederm, Restylane, and Belotero are HA-based. The characteristic feature of HA fillers is the possibility of revision: the hyaluronidase enzyme dissolves the HA material within hours; In case of unwanted contour or asymmetry, the physician can quickly reverse it with hyaluronidase injection. This “undo button” makes HA a safe option, especially for patients having fillers for the first time and for high-risk areas (lips, under eyes).

HA products, cross link stream Classified by (cross-linking percentage) — low cross-linking (soft HA), more fluid, suitable for superficial lines; High cross link (firm HA) for more structured, deep volume and contour. Example: Juvederm Ultra, Restylane-L is low-medium cross-linked and for lip and periocular areas; Juvederm Voluma and Restylane Lyft are highly cross-linked, for cheekbone and jawline volumization. The duration of effect is 6-18 months, on average 12 months.

2. Calcium Hydroxyapatite (CaHA)

Calcium hydroxyapatite is a mineral compound found naturally in bones. Its commercial form, Radiesse, is more permanent (12-18 months) and structurally harder than HA. The unique quality of CaHA fillers is their biostimulative effect: while HA simply provides volume, CaHA also stimulates the body's endogenous collagen production. Histological studies show that CaHA activity improves after 3-6 months, in part due to “biointegration”—the filler material gradually transforms into the body's own tissue architecture. Its resorption is slower than HA; 50% may still remain after 18 months. Contraindication: lip and dynamic perioral areas (to moving muscles), the rigidity of CaHA may cause grimace (distortion). Best use: cheekbone volume, nasolabial fold deep filler, chin augmentation.

3. Poly-L-Lactic Acid (PLLA/Sculptra)

Poly-L-lactic acid is an FDA-approved synthetic biopolymer, Sculptra is its primary trade name. PLLA is not a "filler" but a "biostimulator" — the product itself does not provide volume, on the contrary, it triggers the body's collagen production. After injection, fibroblasts proliferate around the PLLA particles and collagen deposition begins. Clinical results begin in 4-6 weeks, full effect 3-6 months; and the effect can last 2+ years — the longest of any filler. Advantage: permanent-like result, natural facial rejuvenation (collagen structure reconstruction). Disadvantage: early photographic image is unclear (minimal effect in the first week), unconscious patients may think "nothing happened"; Additionally, the risk of nodule formation (granuloma) is 1-2% if the injection technique is incorrect. Side-by-side biostimulation use: for full face volume loss in middle-aged women (40-55) ("Brazilian Butt Lift" aesthetic philosophy - correcting global resorption).

4. PMMA (Polymethylmethacrylate / Bellafill)

PMMA is an acrylic copolymer and is marketed under the trade name Bellafill. The characteristic feature of PMMA is its permanence—in the "long-lasting, semi-permanent" category in FDA approval; resorption is very slow, can persist for 3+ years. Its mechanism is CaHA-like: While PMMA particles act as a scaffold (skeleton), the body's collagen storage increases. Contraindication: Unlike HA, hyaluronidase cannot dissolve PMMA — if complications occur (nodule, granuloma, overcorrection), it may be necessary to physically remove the problem (surgery). Area of ​​use: areas where a very permanent effect is desired (nasolabial fold deep filler, marionette), but in areas that cannot be easily corrected; It is used relatively little in Türkiye because HA and CaHA are safer (reversible) options.

5. Autologous Fat Transfer

The patient's own fat tissue is removed by liposuction (abdomen, flanks), made into micro-cracks, and injected into the face. Advantage: biocompatible (risk of rejection is close to zero), not reversible but has a "natural" filler. Disadvantage: resorption is unpredictable — 30-70% of injected fat may be lost in the first 3-6 months; repeated injections ("overfat") may be required; It is a technique that requires experience, with a high risk of infection (from the liposuction site), a high risk of asymmetry. Usage: In middle-aged patients (50+) who want global facial volumization, tolerant of more than one treatment. The advantage is that it provides a "cellular reservoir" against aging in the long term - autologous fat carries not only volume but also regenerative factors (HGF, VEGF, TGF-β).

Rheology and Product Selection Criteria

G-Prime and Viscosity: The physical behavior of fillers is measured by the science of rheology. Main parameters: (1) viscosity (viscosity) — fluidity of the material; lower viscosity = more fluid, conforms to soft lines; high viscosity = structured, provides deep volume. (2) cohesivity (cohesive retention) — filler particles may remain cohesive or separated (non-cohesive); Coesive fillers are better for thread injection, non-coesive is better for bolus (pellet) filler.

Lift Capacity: It is the ability of a fill to horizontally "provide" beneath itself. High lift capacity fillers (HA Voluma, CaHA, PLLA) are resistant to vertical downward forces — suitable for jawline, cheekbone, temple lift. Fillers with low lift capacity (soft HA) are preferred in dynamic areas (lip, perioral) because they do not restrict movement.

Product Selection Algorithm: The physician asks the following questions for each injection point: (1) What is the skin thickness in this area? (superficial vs. deep). (2) How much volume is required? (in mm). (3) Is this region dynamic (motion) or static? (4) What is the desired duration of action? (6 months, 18 months, 2+ years?). Then, he chooses the product — example: Thin-walled superficial lines (bunny lines, lip border) = soft HA (Juvéderm Ultra, Restylane Refine); nasolabial fold deep filler = medium-highly cross-linked HA or CaHA; cheekbone volumization = highly cross-linked HA or CaHA; global facial resorption = PLLA (Sculptra); very persistent marionette line = CaHA or PMMA.

Indications

Volumetric Indications (Volume Loss):

• Middle-advanced age percent volume depletion (30-70 years): Cheekbone, midface, temporal, chin volume loss → face hanging, sunken appearance
• Postbariatric (after weight loss) facial atrophy: Patients who lose a lot of weight need significant facial filler — global soft tissue resorption
• Post-facelift "hallowness": If cheeks look empty after a facelift, volumization is necessary
• Genetic face shape correction: Thin-boned, asymmetrical facial contouring

Dynamic Line Fill (Static Line Correction):

• Nasolabial fold (NLF): The most common indication; While Botox reduces dynamic lines, filler fills in static depth.
• Marionette line (DAO region): Lines descending from the corner of the mouth to the chin; The combination of deep filler + DAO Botox is ideal
• Bunny lines: Lines on the side surface of the nose; Low dose soft HA is sufficient
• Lip lines (perioral rhytides): Lines around the lips; very fine needle (0.3 mL) soft HA, intradermal technique
• Chin (menton) sulcus: Midline depth under the chin; vertical lifting filler

Contour Indications:

• Cheekbone augmentation: High viscosity HA or CaHA on zygomatic bone; "high cheekbone" appearance
• Jaw contouring: Definition at the mandibular margin line; Botox (masseter) + filler (border line)
• Chin projection (mentoplasty non-surgical): Volume to the chin tip; Botox (mentalis) filler after weakness
• Temple hollowness: Depression in the temple area; medium-long acting filler (CaHA ideal)
• Lip augmentation (lips size, definition): Thickness of the lip, corner definition

Medical (non-aesthetic) Indications:

• Acne scarring (atrophic scar) correction: Sunken acne pits; filler temporary support, needing + filler combination is better
• Lipoatrophy (HIV-related facial wasting): Facial atrophy due to anti-HIV drugs; PLLA (Sculptra) FDA approved

MD Codes and Clinical Injection System

Developed by Mauricio de Maio (dermatologist, Brazil) MD Codesis the standard clinical reference injection strategy worldwide. The system maps the face with "vectors" (directions) and "zones" and recommends the optimal injection depth, technique and volume for each zone.

Main Vectors:

• Vector 1 (Sagittal Midline): Central vertical line of the face (middle forehead, nose, chin); symmetry reference
• Vector 2-3 (Lateral Face): Masseter, mandibular margin; lateral contour
• Vector 4-5 (Top Face): Temporal, cheekbone; upper 3rd volumization

Injection Plans (Depth Selection):

• Subdermal (under the dermis, 2-3 mm): Fine lines, lip border definition; soft HA, fine needle (30G)
• Subcutaneous (subcutaneous, over the fat layer): Medium volume, line fill; medium cross-linked HA, threading technique
• Supraperiosteal (on bone): Maximal volume, contour; highly cross-linked HA, CaHA, PLLA; bolus technique

Threading vs. Bolus Technique: "Threading" means advancing the cannula in the correct direction and depositing the filler while retracting it; "bolus" is injecting volumetric filler into a single point. Threading, linear lines (NLF); bolus, volume-needed areas (cheekbone).

How to Apply

Filler injection is an "art-and-science" procedure; The physician must know a combination of facial anatomy, filler rheology, patient anatomical goals, and technical prowess.

1. Consultation and Photography: The physician documents the face as anterior, oblique, profile and smile. The patient identifies "problem areas." The physician objectively analyzes volume loss, asymmetry, lines — subjective physician's diagnosis, etc. Are patient expectations consistent?
2. Preparation and Marking: The skin is cleaned with antiseptic. Injection points are marked with a pencil (MD Codes reference). Optional: 10 minutes of topical anesthetic cream (lidocaine), or local anesthesia with 1:100k adrenaline (block or infiltration). Adrenaline reduces bleeding and makes it easier to distinguish the filler by "vasipation" (colouration).
3. Needle vs. Cannula Selection: "Needle" (25-27G, sharp) more precise, less bleeding; "cannula" (22-25G, blunt) safer (reduced risk of nerve/artery damage), less pain. Modern protocol: cannula preference, especially in risk areas (near the nasolabial fold = facial artery). Needle, if there is a need for precise injection in the lip border definition.
4. Injection Technique:
   • Threading: 90° entry of the cannula into the skin, then advancement in the longitudinal direction (0.5-1 mL per pass), depositing the filler while retracting. Again: parallel passes, crosshatch pattern (X-shaped drawing), more homogeneous distribution.
   • Bolus: Single point, slightly larger (0.3-0.5 mL), more structured filler (high cross-link, CaHA). Cheekbone for chin projection.
   • Fan technique: Cannula advancement from a single entry point to multiple directions; It is fast for large areas (midface).
5. Volume Titration: A conservative approach is recommended — “go low, build up”. The first session often injects 60-70% of the planned volume; Re-evaluation with palpation + appearance after 2 weeks, need for touch-up? This reduces the risk of overcorrection.
6. Post-injection Care: The area is gently pressed (hemostasis). First 24 hours: ice (reduction of swelling/ecchymosis), ibuprofen (unless it increases bleeding), no heavy make-up / intense massage. First week: avoid heavy exercise, sauna, alcohol — to prevent the filler areas from slipping. "Swelling may peak at 24-48 hours" and "final result 2 weeks" are explained to the patient.

Contraindications

• Pregnancy and breastfeeding: Insufficient safety data; treatment is postponed
• Active skin infection / herpes labialis: Open lesion in the application area; risk of spreading infection
• Severe immunosuppression: HIV/AIDS (CD4 < 200), active cancer treatment, organ transplantation; high risk of infection
• Keloid/hypertrophic scar history: Risk of keloid development in the injection area
• Anaphylaxis history to HA / filler ingredients: Allergy testing or another type of filler is considered
• Heavy use of anticoagulants/antiplatelets: INR > 3, aspirin + clopidogrel combination; high risk of ecchymosis; Not an absolute contraindication, done with caution
• Active litigation (patients in litigation): Ethical contraindication — if there is a risk of complications, it makes sense to wait for the safer moment

Duration of Effect and Recovery

Backfill Timing Table:

Effect duration and resorption according to filler products

Product Type	Effect Start	Full Effect	Average Effect Duration	reversibility
Hyaluronic Acid (HA)	immediately	3-7 days	6-18 months (avg. 12)	Yes (hyaluronidase)
Calcium Hydroxyapatite (CaHA)	immediately	1-2 weeks	12-18 months	Partial (surgical removal)
Poly-L-Lactic Acid (PLLA)	4-6 weeks	3-6 months	2+ years	no
PMMA (Bellafill)	immediately	1 month	3+ years	no
Autologous Fat	immediately	3-6 months	1-5 years (variable)	Partially (reinjection)

Stage-by-Step Result Development:

Day 0 (Practice): Instant volume increase — the filler material takes up physical space under the skin. Swelling, erythema mild; The patient immediately feels "full". HA fillers can swell a lot in the first 24-48 hours — this natural, hydrophilic HA absorbs fluid.

Days 1-3 (Early Proofreading): Bloating may peak and then gradually decrease. Ecchymosis (purple around injection points) may appear mild—resolving within 5-7 days. During this period, the physician may seem "overcorrected", but this is normal.

Week 1-2 (Seeing the Full Effect): With HA fillers, swelling is mostly reduced and the actual result is clearly visible. The filler is "settled". If the patient is told "final result 2 weeks", it is respected - otherwise the request for "ineffective" will come after 1 week.

Weeks 2-12 (Impact Plato): HA fillers remain stable during this period. Biostimulation begins in CaHA and PLLA — the collagen structure increases, the result becomes even better (visible in weeks 4-8). With PLLA, there is not much change in the first 6 weeks (which may shock patients), but clear improvement is seen after weeks 6+.

Months 2-6 (Long Term Plateau): Fillers remain stable. No regression in HA, minimal in CaHA. In PLLA, collagen deposition continues and the results improve slightly.

Month 6-12 (Beginning of Resorption): HA is slowly resorbed after 6 months — renewal injections are different during this period. CaHA 12-14 months, PLLA 2+ years. Ask the patient "Are you full?" In this period, yes, the renewal time is approaching.

Month 12+ (Renewal): Typical HA reinjection interval: 9-15 months. It is almost the point where 70-80% of the disease is still seen; Not a complete loss, but a "slight regression". Reinjection is known as "top up" or "maintenance".

Risks and Complications

Common (mild, transient):

• Swelling at the injection site (1-3 days, HA may become more swollen)
• Ecchymosis/hematoma (resolves within 3-10 days)
• Mild pain/tingling sensation (1-2 days)
• Low asymmetry (volume imbalance between two injections) at low dose — corrected by touch-up
• Allergy-like mild reaction (rare, usually not due to product purity and sterility, but the body's response to filler proteins)

Moderate-Serious (rare, under 0.1% with experienced physicians):

• Vascular Occlusion (CRITICAL RISK): The filler may compress or thrombus the arterial vessel—resulting in tissue necrosis. The most risky areas: nasolabial fold (facial artery path), glabellar region (supratrochlear / supraorbital artery), temporal region (superficial temporal artery). Clinical findings: sudden pain, paleness, risk of gangrene. Emergency response: hyaluronidase (for HA), massage, nitropaste, oxygen, steroids; hyperbaric oxygen (HBO) or reconstructive surgery in severe cases. Prevention: knowledge of arterial anatomy, slow injection, before aspiration (does needle/cannula aspiration come out with blood?), retrograde injection technique (moving away from the artery), immediate hyaluronidase injection if there is a suspicion that it has caught the vessel.
• Nodule / Granuloma Formation: Foreign body reaction of the body to the filler material — especially in PLLA (Sculptra) and PMMA (1-2%). Clinical: palpable, hard, small grains may appear months later. Treatment: rotator injections (steroid, hyaluronidase), or surgical removal. Prevention: Proper injection technique, adequate dilution (saline + lidocaine mesh mixture for Sculptra and waiting for 1-2 weeks, followed by massage), experienced injector.
• Overcorrection/Asymmetry: Too much volume, or bilateral imbalance — the face appears "puffed up" or "lopsided." HA can be reversed with hyaluronidase; More difficult in CaHA/PMMA. Prevention: titration, conservative approach, bilateral symmetry control.
• Infection: Rare (< 0.5%) but serious. Clostridium botulinum (bacteria) contamination (different from the Medicis "Botox" contamination that occurred in April 2020, filler infection is rarer). Clinical: purulent discharge, warmth, erythema, fever. Treatment: culture, antibiotic IV, possible drainage. Prevention: sterile technique, one-use vials.
• Retinal Artery Occlusion (RAO): Super-medial indentation in the glabellar region, retinal vascular occlusion as a result of the filler entering the intracranial/ophthalmic artery system. Serious complications, risk of permanent blindness. Clinical: urgent pupil dilation, vision loss. Rare, but possible. Prevention: very careful in the glabellar area, medial injection avoid, cannula preference, aspiration.
• Skin Necrosis: After vascular occlusion, tissue oxygen deprivation, skin blackening. Eyebrows and corners of lips are risky. Scar in the long run. Emergency intervention: hyaluronidase, warm compresses, topical care, antibiotics.
• Late Five-Year Complications: Migration — the filler may move over time, under gravity or coping; hyaluronidase granuloma (cyst-like, sterile), palpability, visible asymmetry. Migration is less common in PMMA/CaHA (structural), more likely in HA (fluid).

Psychiatric/Ethical Complications:

• Body Dysmorphic Disorder (BDD): The patient never sees the result of the injection as "satisfactory" and requires repeated touch-ups. The physician should recognize such patients (BDD screener) and not treat them.
• Addiction to Fillers: Some patients become “addicted to fillers” — increasing their desire for injections every 2-3 months. Ethical consultation required.

Alternatives and Combination Therapies

Alternative Treatments (Instead of Fillers):

• PDO Thread Lift: Mechanic lifting, mini-invasive, 1-2 years effect; Provides structural lifting (suspension) unlike filler
• Laser Resurfacing / Fractional Laser: Improve skin quality (collagen remodeling), reduce fine lines; surface renewal, not volume
• Radiofrequency (RF) Microneedling: Dermal collagen contraction; thermal energy, low downtime
• Ultrasound (HIFU): Ultrasound Focused energy, in-depth collagen tightening; non-invasive facelift

Combination Therapies (Synergy):

• Botox + Filler: The most common combination. Botox addresses dynamic lines (from facial expressions), filler static lines, and volume loss. Example: glabellar botox + nasolabial filler.
• Filler + Micro-needling: Filler volume + skin quality (collagen induction treatment). Post-filler 1-2 weeks later, gentle micro-needling increases collagen remodeling.
• PLLA+Laser/RF: Maximizing biostimulation — PLLA collagen buildup + laser/RF collagen remodeling in parallel.
• Padding + PDO Thread: Combination of volume (filler) + mechanical lift (thread); Maximum detailing of jawline, cheekbone, chin contour.
• Filler + Profhilo (skinbooster): Volume + skin quality. Profhilo intradermal hydrating booster can be applied next to HA fillers; global skin hydration and laxity improvement.

Hyaluronidase: Reversal of HA Fillers

The reversibility of HA fillers is possible thanks to the hyaluronidase enzyme. Hyaluronidase is highly resorbable by breaking down the HA polymer into monomers—80-90% return within 24-48 hours after injection. In clinical practice: if the patient's lip is "ballooned", the chin looks too "puffed", or there is asymmetry, the physician may inject hyaluronidase and the filler will return within hours. This is the caution advantage of HA. Hyaluronidase dosage: type according to person, site, filler volume (usually 50-150 IU localized, or 50 IU/mL of hyaluronidase diluted in 1.5 mL normal saline). Contraindication: allergy to hyaluronidase (very rare). Side effects: local inflammation, transient edema. Hyaluronidase is ineffective in CaHA and PMMA — so these fillers are riskier (choose carefully).

Frequently Asked Questions

Q: Is filler injection painful?
A: Minimal pain. Modern cannulas (blunt) are less painful than fine needles. If anesthesia (topical or local infiltration) is applied, almost no pain is felt. Most patients describe "mild stinging".

Q: How many months does the filler last?
A: It depends on the product. Hyaluronic acid 6-18 months (average 12), CaHA 12-18 months, PLLA 2+ years. Individual metabolism varies depending on the injection site (lip may resorb faster, cheekbone more slowly) and filler product.

Q: What happens if my face is asymmetrical after filler?
A: Hyaluronidase can be injected into the HA filler — it returns in 24-48 hours. Hyaluronidase does not work in CaHA/PMMA; A medical check-up is necessary, additional intervention (steroid injection) or partial absorption may be necessary.

Q: Will my face look wider in the areas where fillers are applied?
A: No; If the correct application and appropriate volume selection for the area is made, the face looks younger and more defined. If overcorrection is performed (too much volume), the face may appear momentarily swollen (first 48 hours), then normalizes. Proper filler: slims the face and makes it defined.

Q: What should I not do after a filler injection?
A: First 24 hours: heavy make-up (pressure), intense massage (moves the filler), sauna/hammam (HEAT can increase arterial dilatation), heavy exercise (blood pressure increases = bloating). First week: heavy physical activity, extreme heat avoidance.

Q: Is the filler permanent?
A: No; All fillers (HA, CaHA, PLLA, PMMA, autologous fat) are temporary — resorbing in hours, months, or years. “Permanent” filler (PMMA, PLLA) can last 3+ years but is not 100% permanent. If you want to maintain it, replacement injections are given.

Q: Can I also have Botox applied to the areas where fillers are applied?
A: Yes, the combination is the standard protocol. Botox addresses dynamic lines (without contraction), filler addresses static volume. Example: glabellar botox (corrugator/procerus) + nasolabial filler (static line). It can be applied on the same day or 1 week apart (physician preference).

Q:How often does vascular occlusion occur?
A: Very rare with experienced physicians — estimated at less than 0.1%. Risky areas: nasolabial, glabellar, temporal. Although rare, it is a serious complication that can be life-threatening. Urgent hyaluronidase intervention (if HA filler) is required.

Q: How long after a filler injection will I see results?
A: Immediately. Fillers instantly provide volume under the skin. However, bloating may peak in the first 48 hours; real final result after 2 weeks. Biostimulators (PLLA, PMMA) appear after 4-6 weeks.

Q: Do filler injections have side effects?
A: Common side effects: swelling (48 hours), ecchymosis (3-10 days), mild pain. Rare side effects: infection, nodule (granuloma), vascular occlusion, allergic reaction. With experienced physicians, the risk of serious complications is less than 0.1%.

Q: At what age can I start filler injections?
A: Typically ages 30-40 and above, when significant volume loss and lines begin to appear on the face. However, “preventive filler” can also be done on younger patients (25+) — volume optimization before lines form (like a “preventive” version of Botox).

Q: Is filler injection considered surgery?
A: No. Filler injection is classified as "non-invasive" or "mini-invasive" — 10-15 minute office procedure, no downtime. It is non-surgical, so there is no general anesthesia, hospitalization, or convalescence.

Dr. Hamza Gemici Comment

"Filler is the most powerful non-invasive weapon against aging. However, its success depends on the physician's knowledge of facial anatomy, the rheology of filler products and patient selection. In the advanced age group (50+), I prefer global volumization (biostimulators such as Sculptra) over global facial resorption — this provides a more natural and social appearance. For young patients (30-40), a conservative approach with HA fillers is safer. The risk of vascular occlusion is serious; anatomical knowledge, slow technique and hyaluronidase." "Immediate access is essential. In my clinical practice, I view filler injection as 'artistry' — every face is different and the protocol should be individualized."
