The philosophy of filler
Hyaluronic acid-based fillers have become one of the most used tools in aesthetic medicine in the last twenty years. But this rise also produced a side effect: in some physicians and clinics, filler began to be used like a "fullness-look varnish" sprinkled on the skin. However, filler is a reconstruction tool that settles into deep tissue, structural support, and architectural deficiencies.
Natural filler does not add fullness to a face; it restores the support the face has lost over time. For this reason, when looking at a photo, the question asked is not "did they get filler?", but "why do they look more refreshed?". Where this question is not asked, filler has usually been overdone.
Structural, not superficial
The correct placement for filler is often not under the line, but at the supportive points of the face. Cheekbone structure, jaw angle, temporal region, midface support — these are the areas where filler draws an "architectural line". Directly filling a superficial line, while seemingly satisfying in the short term, leads to the face looking slightly puffy and "overdone" in the long term.
Therefore, my clinical preference is; first deep support, then superficial fine corrections. Filler applied out of order disrupts the natural light-shadow balance of the face, tires the mimic muscles, and creates a "filler face" that is difficult to reverse years later.
Clinical note:The decision to fill a patient's lips, cheekbones, or chin should be made not with the photo taken that day, but with the photo to be taken 20 years later. This decision hour is the careful hour of a good clinician.
Importance of product selection and rheology
Filler products differ in consistency, cross-linking density, and elastic behavior. These properties, which we call "rheology", determine which region the product is suitable for. A soft, fluid product for the lips; a firm, shape-retaining product for cheekbone support; an intermediate viscosity is preferred for the nasolabial region.
A product placed in the wrong area with the wrong rheology can leave spherical swellings or nodules visible for years. Most of these errors are not technical, but product selection errors. Knowing the rheological profile of each product I use in the clinic is half the treatment.
- Lips — soft, high water-retaining products.
- Cheekbones — high projection, shape-retaining products.
- Under-eye — light, non-water-absorbing special formulas.
- Jawline — firm, ground-supporting products.
- Skin quality (skinbooster) — low cross-linking, moisture-focused products.
Attention:Permanent fillers (biopolymer, silicone) mostly leave granulomas and deformations over the years. I recommend avoiding these irreversible procedures.
