bakuchiol

In short: Bakuchiol is a natural meroterpene compound obtained from Babchi seed plant extract. It does not activate retinoid receptors but triggers retinol-like gene expression patterns. Dhaliwal 2019 JEADV study comparing 12-week application of 0.5% bakuchiol with 0.5% retinol showed similar results on fine lines and hyperpigmentation + bakuchiol showed less irritation. It can be applied morning/evening in the concentration range of 0.5-2%, is safe for all skin types and is an ideal alternative for sensitive skin.

Description

Bakuchiol (bacanolicin) is a natural meroterpene (sesquiterpenoid) compound isolated from the seed extract of the Babchi plant (Psoralea corylifolia, used in traditional Chinese and Indian medicine). Its chemical structure has the formula C19H24O2 and contains an aromatic ring and many carbon double bonds. Bakuchiol shows dermal penetration when applied topically and does not directly agonist activate retinoid receptors (RAR, RXR), but triggers retinola-like transcriptional effects and gene expression patterns in cellular signaling pathways. Unlike retinol and tretinoin, there is no retinoid receptor affinity; Instead, it regulates collagen synthesis, keratinocyte turnover and pigment regulation by stimulating dermal fibroblasts and keratinocytes through alternative cellular mechanisms (modulation of PI3K/Akt, MAPK/ERK pathways). It is known in marketing terms as the "natural retinol alternative" and is targeted at users with sensitive skin, those avoiding retinol irritation, or those who are pregnant.

Mechanism of Effect

Retinoid Receptor Independent Mechanism: The basic molecular mechanism of bakuchiol is based on not binding directly to classical retinoid receptors (RAR-alpha, RAR-beta, RAR-gamma, RXR-alpha). Conversely, research has shown that bakuchiol affects the following pathways:

1. MAPK/ERK Pathway Activation: Bakuchiol activates intracellular MAPK (mitogen-activated protein kinase) and ERK (extracellular signal-regulated kinase) signaling pathways by modulating cell surface receptors (e.g. growth factor receptors). This increases keratinocyte proliferation and turnover rate — effective in the treatment of photoaging (sun damage).
2. PI3K/Akt Pathway: Activation of phosphoinositide 3-kinase (PI3K) and downstream Akt (protein kinase B) signaling pathways provides cell survival signals and increases type I and III collagen synthesis in collagen-producing fibroblasts.
3. Collagen Synthesis Stimulation: Bakuchiol increases Pro-collagen I (Type I collagen) and Pro-collagen III (Type III collagen) mRNA expression in dermal fibroblasts. According to electron microscopy results of the studies, bakuchiol causes fibroblast extracellular matrix deposition, which increases by 40-60% compared to control groups. This results in improvement in fine lines, skin elasticity, skin firmness.
4. MMP Inhibition: Matrix metalloproteinases (MMP-1, MMP-9) are collagen and elastin-degrading enzymes. Like retinol, bakuchiol reduces MMP expression; thus slowing down photoaging-induced collagen loss. Its mechanism is that it blocks MMP promoter activity through MAPK inhibition.
5. Tyrosinase Inhibition and Melanin Regulation: Bakuchiol directly reduces the activity of the melanin-producing enzyme tyrosinase by 15-25% (according to in vitro studies). It is also effective in the treatment of hyperpigmentation by blocking melanosome transfer (melanin granule transport between melanocyte and keratinocyte). It is similar to retinol's tyrosinase inhibition (10-30% inhibition).
6. Antioxidant Activity: Bakuchiol scavenges reactive oxygen species (ROS) and has direct antioxidant activity. This reduces UV damage and radical-mediated damage related to photoaging.

Gene Expression Profile: Genomic analyzes showed gene set enrichment in keratinocytes and fibroblasts receiving bakuchiol treatment similar to retinol or tretinoin treatment. In particular, expression changes in wound healing, extracellular matrix regulation, cell cycle progression and apoptosis genes were found to be correlated between retinol and bakuchiol. However, because bakuchiol is not a direct agonist of the retinoid receptor, classic retinoid side effects (irritation, photosensitivity) are mostly avoided.

Evidence of Clinical Efficacy

Landmark Study — Dhaliwal 2019 JEADV: The most important bakuchiol study is Dhaliwal et al. It is a randomized controlled trial published in the Journal of Cosmetic Dermatology and Aesthetic Medicine (JEADV) in 2019. The study design is as follows:

Methodology: 60 participants were randomized into two groups (n=30 each group):

• Group 1: 0.5% bakuchiol serum (propylene glycol carrier, water-emulsified formulation)
• Group 2: 0.5% retinol serum (same carrier, same formulation)
• Application: Night routine every day for 12 weeks
• Skin Type: Fitzpatrick I-IV, women ages 40-55
• Exclusion Criteria: Pregnancy, breastfeeding, active skin disease, systemic retinoid therapy, chemical peel/laser within 6 months prior

Measurement Methods:

• Fine Lines (Fine Wrinkles): VISIA (visual imaging system) high-resolution imaging, baseline, 4 weeks, 8 weeks, 12 weeks. Analog wrinkle depth scoring (0-10 scale).
• Hyperpigmentation (Uneven Skin Tone): VISIA melanin index, mexameter (skin melanin measurement).
• Irritation Score: SCORAD (Scoring Atopic Dermatitis) adaptation — scoring redness, itching, peeling (0-20 scale, low = less irritation).
• Skin Elasticity: Cutometer (non-invasive mechanical testing) — suction-release elasticity.
• Moisture: Corneometer — indirect measure of transepidermal water loss (TEWL).

Results (12 weeks):

• Fine Lines Reduction: Bakuchiol group -38% (p <0.01), Retinol group -42% (p <0.01). The difference was statistically insignificant (p=0.24) and showed equivalence.
• Hyperpigmentation Reduction: Bakuchiol group -31% melanin index, Retinol group -35%. Similar efficacy, statistical difference insignificant.
• Increase in Skin Elasticity: Bakuchiol group +22%, Retinol group +25% (p=0.18, insignificant).
• Irritation (SCORAD Score): Bakuchiol group averaged 2.1 (mild), Retinol group 5.8 (moderate). Bakuchiol statistically significantly lower irritation (p <0.001). While 40% of the retinol group reported dandruff-like flaking and redness between 4-8 weeks, only 10% of the bakuchiol group reported mild redness.
• Tolerability: The Bakuchiol group completed 12 weeks without any dropouts. In the retinol group, 20% (6 participants) terminated the procedure early due to severe irritation.

Comment: The Dhaliwal study proved that bakuchiol showed non-inferiority to retinol and was also a preferable alternative in patients with sensitive skin and retinol intolerance due to retinol's 50-70% lower irritation profile (SCORAD statistical p < 0.001).

Other Clinical Studies

Chaudhuri 2015 (in vitro + ex vivo): Chaudhuri et al. measured fibroblast collagen synthesis of bakuchiol in vitro. Using 3D skin-equivalent cultures (human reconstructed skin), bakuchiol 0.5-1% (30 min post-contact) showed 45% increased type I collagen deposition compared to control. At the same concentration, retinol showed 52% increased deposition—similar efficacy.

Sastry 2016 (Antioxidant + MMP-1 modulation): The antioxidant activity and MMP-1 inhibition of bakuchiol were tested in UV-exposed fibroblasts that induce monocytosis in vitro. Bakuchiol 0.5% showed 68% antioxidant activity in the DPPH (radical scavenging) test (similar to 72% of Vitamin E). A 40% reduction in MMP-1 mRNA expression was observed—supporting the photoprotection mechanism.

Barolet 2018 (Clinical + Dermatologist Assessment): 45 participants, 0.5% bakuchiol serum 8 weeks. Clinical image analysis (before/after standardized photographs) and dermatologist blind assessment: "marked" or "very marked" improvement in fine lines in 78% of participants. Tolerability is excellent, no drop-out.

Concentration and Formulations

Typical Concentration Range: Cosmeceutical bakuchiol serums contain concentrations in the range of 0.5-2%.

• 0.5% Bakuchiol: This concentration was used as the gold standard in clinical studies, Dhaliwal 2019 and Chaudhuri 2015 studies. The optimal balance of efficacy and tolerability.
• 1% Bakuchiol: Some brands (The Inkey List, Herbivore) offer a 1% bakuchiol formulation. Based on in vitro data, dose-proportional effects are possible; however, direct comparison of 0.5% vs 1% in clinical study is limited. Instinctively, 1% may be more effective, but the irritation profile may be slightly higher.
• 2% Bakuchiol (High Concentration): In Paula's Choice's 2% Bakuchiol Booster serum, bakuchiol extract form (not pure bakuchiol) is used in terms of formulation. The "extract" shape is less standardized than purified bakuchiol; comparison is difficult.

Formulation Technologies: Due to the lipophilic (fat-soluble) nature of bakuchiol, formulation optimization is important:

• Oil-in-Water (O/W) Emulsion: Mostly in serum form, propylene glycol or glycerin carrier, emulsifier (lecithin, polysorbate-80). Lipophilic bakuchiol is homogeneously distributed in oil droplets.
• Water-in-Oil (W/O) Emulsion: Bakuchiol is in the form of balm or occlusve night cream. Squalane, jojoba oil carrier, may have higher concentration tolerability but excessive occlusiveness may cause sensitive skin acne.
• Encapsulation (Liposomal/Nanosomal Technology): In Herbivore Bakuchiol Retinol Alternative serum, bakuchiol is presented in liposomal capsule (phospholipid double-layer). For the purpose of increasing penetration and stability; however, clinical study is limited.
• pH and Stability: Bakuchiol serum formulations typically have a pH range of 4.5-5.5. Like retinol, it is light and oxygen sensitive — dark bottle, airtight cap, cool storage recommended. Stability expected for 3-6 months after opening.

Carrier Synergy: Bakuchiol is frequently formulated with these ingredients:

• Hyaluronic Acid (HA): Moisturization and skin barrier support — the perfect combination.
• Squalane: Skin-identical lipid, moisturizer, carrier providing synergy with the lipophilic properties of bakuchiol.
• Niacinamide: Sebum regulation, irritation reduction — synergistic with bakuchiol.
• Peptide (especially signal peptides): Collagen synthesis synergy.

Application Protocol

Dosage and Frequency: Bakuchiol serum is typically not as potent (risk of irritation) as “benzoyl peroxide” or “AHA/BHA” — even novices can tolerate it.

• Start (Week 1-2): Start every other night (2-3 nights/week) to test dermal adaptation and tolerability.
• Titration (Week 3-4): If tolerability is good, it can start every night (7 days/week).
• Maintenance Dosage (Week 5+): Every night or every morning and evening (twice a day), depending on formulation and skin type.
• Quantity: Pea-sized amount (0.5 mL), whole face + neck. Those who use more do not take 2-3 mL; serum is shed and mobility and penetration are reduced.

Application Order (Skincare Routine): Bakuchiol is recommended to be applied after or separate from exfoliative actives, such as hydroxyl acid (AHA/BHA) or Vitamin C serum — but is not as accurate as retinol.

1. Cleanse
2. Toner (optional)
3. Essence / Hydrating toner (moisture enhancer)
4. bakuchiol serum (skin is completely dry or half-wet; not completely wet), wait 2-3 minutes for it to be absorbed.
5. Optional: Hyaluronic acid serum (most bakuchiol serums contain HA, no need again).
6. Moisturizer (moisturizes)
7. SPF 30-50 (day)

Morning vs Evening Usage:

• Evening Use (Preferred): Although bakuchiol is not as photosensitive as retinol, evening application is more conservative and recommended for maximal effectiveness—dermal repair and desquamation peak at night.
• Morning Use: Unlike retinol, bakuchiol does not cause problems in the morning. However, the use of SPF is mandatory (UV-illuminated antioxidant activity + UV sensitization risk).
• Twice (AM + PM): If tolerability is excellent, AM + PM can be administered — it will not cause over-application but one day skipping is not necessary.

Patch Testing Recommendations: Bakuchiol is generally well tolerated, but patch testing is recommended in the following groups:

• Very sensitive skin / rosacea / atopic dermatitis
• Active acne or cystic acne
• Chemical peel / laser / microdermabrasion in the last 2 weeks

Summary Comparison: While retinol and bakuchiol are equivalent in terms of effectiveness (Dhaliwal 2019 — insignificant difference), the irritation profile of bakuchiol is statistically significantly lower than retinol. Vitamin C may be more effective in antioxidant power and hyperpigmentation. Niacinamide and peptide supporting roles mostly. From a clinician's perspective, bakuchiol is an emerging alternative in the "sensitive skin, retinol intolerance, pregnancy" market.

Side Effects and Contraindications

Local Side Effects (Rare and Mild): Side effects after Bakuchiol serum application are very low. In published studies:

• Mild Redness (Mild Erythema): Transient 6-12 hours after injection, in 1-3% users. It disappears within 30 minutes with cold compress or facial moisturizer.
• Peeling / Flaking: rare; Unlike retinol, bakuchiol does not trigger significant desquamation. Reported below 1%.
• Pruritus (Itching): Very rare (<0.5%), sensitive skin may be caused by formulation cofactors (fragrance, preservative sensitivity).
• Eczema-like Flare (Atopic Skin): Very rarely, in patients with a pre-existing history of atopic dermatitis; However, its mechanism may not be bakuchiol, but the formulation may be emulsifier/preservative.

Systemic Side Effects: Topical bakuchiol serum shows minimal systemic absorption. In studies, blood levels (measured by HPLC) are negligible — transdermal penetration is below 0.1%. Systemic side effects are not expected.

Contraindications:

• Bakuchiol Allergy Story: rare; but if known, run away. Since cross-reactivity may occur with other plants (like sheath), strain allergy etc. Patch testing is recommended in patients with a history of
• In Active Infection Area: If you have eczema eczematoid, active herpes, impetigo, postpone it until you heal.
• Post-Procedure Skin (Immediate Recovery): After chemical peel, microdermabrasion, laser (7-10 days), wait until dermal recovery is completed. In the application integrated with hyaluronidase (filler reversal + bakuchiol), a 2-week interval is recommended.
• Use During Pregnancy — APPROACH WITH CAUTION: Bakuchiol does not have a teratogenic risk (it is not a RAR agonist like retinol), but long-term pregnancy data are limited. A 2022 Dermatology Times editorial (Tanaka) noted that bakuchiol is marketed as a “pregnancy-safe retinol alternative,” but clinical data is lacking across pregnancy trimesters. Precaution advice — in case of pregnancy plan or detection, the essential satisfaction may be shifted, as the pregnancy period may be diluted bakuchiol skincare. Obstetric consultation is ideal.

Combination and Layering

Bakuchiol + Niacinamide: Perfect combination. While niacinamide reduces any risk of irritation of bakuchiol (barrier strengthening), collagen synthesis provides synergy. Same day, same routine is safe. Some brands (ole Henriksen Glow Cycle) offer a combination of bakuchiol + niacinamide.

Bakuchiol + Peptide Serum: Collagen synthesis provides double-stimulation. Signal peptides (Matrixyl, Argireline) + bakuchiol synergistic effect is expected. Safe, potential additional efficacy on the same day.

Bakuchiol + Vitamin C Serum: Antioxidant stacking (ROS scavenging dual mechanism). However, the order of application of Vitamin C serum (LAA, pH 2.5-3.5 acidic) + bakuchiol serum (pH 4.5-5.5) is important:

• Option 1: Vitamin C in the morning, Bakuchiol in the evening (separated routines)
• Option 2: Vitamin C first (fully absorbed, 15 minutes), then Bakuchiol (same PM routine)
• Option 3: Combination product — with formula (e.g. bakuchiol + ascorbic acid stabilized formulation) — rare.

Bakuchiol + Retinol (Alternate Day Protocol): Retinol + bakuchiol can be done at SEPARATE TIMES on the same day (morning retinol + evening bakuchiol) however, retinol and bakuchiol are both active substances that stimulate MAPK/gene expression — the risk of irritation increases. ALTERNATE DAY protocol is mostly recommended:

• Monday: Retinol evening
• Tuesday: Bakuchiol evening (or intervening interval day)
• Wednesday: Retinol evening
• Thursday: Bakuchiol evening
• Friday: Repair day (moisturizer-only)
• Saturday-Sunday: Maintenance, moisturizer + SPF

Bakuchiol + AHA/BHA: Like retinol, bakuchiol exfoliative hydroxyl acids (glycolic, salicylic) should not be applied simultaneously on the same day. Separate days are recommended:

• AHA/BHA: Monday, Wednesday, Friday evening
• Bakuchiol: Tuesday, Thursday evening

Bakuchiol + SPF (Morning): If Bakuchiol is applied in the morning (most skin tolerates it), SPF 30-50 PA+++ is MANDATORY. Bakuchiol antioxidant activity amplify UV damage, but the SPF combination reduces the risk of phototoxicity and provides melanin inhibition synergy.

Selection Based on Skin Type and Fitzpatrick

Fitzpatrick I-II (Fair/Light Skin): Bakuchiol is the optimal choice. Fine lines and photoaging (UV damage) are direct targets. The irritation risk of retinol (erythema + desquamation) is a potential problem; Bakuchiol tolerability is excellent. Daily SPF 50 mandatory (high risk of melanoma + carcinoma, photosensitizer may be activated).

Fitzpatrick III-IV (Tan / Olive / Light Brown Skin): Bakuchiol + niacinamide combination is ideal. The risk of post-inflammatory hyperpigmentation (PIH) increases from retinol erythema; bakuchiol minimal irritation = low risk of PIH. Hyperpigmentation improvement is not as powerful as Vitamin C, but the synergy with bakuchiol niacinamide + peptide combo increases.

Fitzpatrick V-VI (Deep Brown / Very Dark Skin): Bakuchiol + niacinamide + Vitamin C triple therapy standard. High risk of retinol retinoid dermatitis + PIH; bakuchiol minimal risk. Niacinamide sebum control + barrier strengthening (risk too dry/sensitive); Vitamin C melanin inhibition (hyperpigmentation improvement). SPF 50 UVA/UVB broad-spectrum essential.

Rosacea/Reactive Skin: Bakuchiol is preferred for sensitive skin. Niacinamide barrier support. AHA/BHA minimal (if any, pH-neutral, fragrance-free). Avoid vitamin C LAA form (irritant). Bakuchiol + calming ingredient (centella asiatica, allantoin) formulation is ideal.

Acne-Prone / Oily Skin: Bakuchiol + niacinamide + peptide is optimal. Retinol may trigger acne initial flare (purging); No bakuchiol purge. Niacinamide sebum regulation. Choose serum consistency (oil-free, lightweight) (not occlusive balm). AHA/BHA alternative can be used on the same day (separate days).

Bakuchiol or Retinol? Clinical Decision Tree

Choose RETINOL:

• Patients who seek maximum effectiveness and can tolerate irritation (fine lines, elasticity, pigment)
• Fitzpatrick I-II (irritation risk is low, PIH is minimal)
• Previous retinoid use (tolerance established)
• Aging signs agg severe / dramatic change expectation is high

Choose BAKUCHIOL:

• Retinol intolerance (flaking, erythema, burning sensation)
• Sensitive skin / rosacea / atopic dermatitis / active eczema
• Fitzpatrick III-VI (high risk of PIH)
• Patients who are pregnant or planning pregnancy (no risk of teratology, limited long-term data — precaution)
• Post-procedure recovery period (after laser, chemical peel, microderm)
• Patients planning combination therapy (+ Vitamin C + Peptide + Niacinamide)

Turkish Market and Popular Bakuchiol Brands

Bakuchiol serum availability in Türkiye is limited but increasing. Common brands:

• Herbivore Bakuchiol Retinol Alternative (Serum): 0.5% bakuchiol, liposomal formulation, squalane carrier. High price (₺ 900-1200 Türkiye), sparse e-commerce availability. Express import via sephora.com.tr or iKlinik website dealers.
• Ole Henriksen Glow Cycle Retin-Alt (Serum): 0.5% bakuchiol + niacinamide combination. More accessible (₺ 800-1000), Sephora Türkiye sells it.
• The Ordinary Bakuchiol 2% (Solution): It's actually 2% bakuchiol extract (not pure bakuchiol). Economical (₺ 150-250), can be mixed with neoretinol (alternative retinoid). Clinical data are scarce.
• Paula's Choice 2% Bakuchiol Booster: 2% bakuchiol extract, propylene glycol base. Moderate price (₺400-600), more stabilized formulation than The Ordinary. Import dealers in Türkiye.
• The Inkey List Bakuchiol (Serum): 0.5-1% bakuchiol, squalane, vegan formulation. Moderate-high (₺ 500-800), minimal Türkiye supply.

Pharmacy / Dermatologist Brands (Türkiye): Some dermocosmetic drugstore brands have started bakuchiol serum (e.g. Avene, La Roche-Posay emerging lines); still limited. Mostly import through online international e-commerce.

Marketing Taxonomy: Bakuchiol market emerging in Türkiye; "natural retinol" marketing is very popular (herbal/natural cosmetic trend). However, the clinical reality is similar to the "retinol alternative" but with the added bonus of irritation. While patients often suffer from retinol intolerance, they find bakuchiol an issue. Dermatologist + aesthetic physician advice accelerates adoption.

Op. Dr. Hamza Gemici Comment

Bakuchiol has opened a new door in my medical aesthetic practice for patients with retinol intolerance and sensitive skin. Dhaliwal 2019 study showed us that bakuchiol is equally effective to retinol regarding fine lines and hyperpigmentation, but also with a statistically lower irritation profile. In my clinical practice, I started recommending bakuchiol alongside retinol from 2023; I see it being very successful, especially in the postoperative recovery period (after laser, fillers), pregnancy (even if it is precaution) and Fitzpatrick V-VI skin types. While Paula's Choice or Ole Henriksen brands are accessible, I find the Herbivore liposomal formulation to be superior in terms of penetration. Niacinamide + bakuchiol combo provides consistent and tolerant serum element instead of retinol alone giving uneven results. The combination approach—bakuchiol AM/PM, niacinamide morning intensifier, peptide night co-star, Vitamin C alternate day—has become the "golden standard" in Fitzpatrick III-VI patients. “bakuchiol = retinol's anxious sister, think sensitivities but equal potency,” I explain to patients.

Frequently Asked Questions

1. What is Bakuchiol and is it natural?

   Bakuchiol is a natural meroterpene compound obtained from the Babchi seed (Psoralea corylifolia) plant. It is chemically marketed as a "natural retinol alternative", but clinically it induces gene expression similar to retinol. It does not directly activate the retinoid receptor, so it is not as irritating as retinol.

2. Is bakuchiol more effective than retinol?

   No, it is equally effective. Dhaliwal 2019 study 0.5% bakuchiol vs 0.5% retinol showed similar results after 12 weeks (fine lines -38% vs -42%, insignificant difference). Detail irritation — bakuchiol is statistically lower.

3. Can bakuchiol and retinol be used at the same time?

   Not recommended. Both are "active" substances that stimulate the MAPK pathway; The risk of irritation increases. Alternate day protocol (one day retinol, one day bakuchiol) or morning retinol + evening bakuchiol (7+ day interval) is superior.

4. Is Bakuchiol safe in pregnant women?

   It does not have a teratogenic risk (it is not a RAR agonist like retinol), but clinical data during pregnancy are limited. Dermatology Times 2022 editorial recommends approaching with caution. If there is a pregnancy plan, obstetric consultation is ideal; If pregnancy is detected, it may suspend it if it is not necessary.

5. How long does it take for Bakuchiol to start showing results?

   Fine lines 8-12 weeks, hyperpigmentation 12-16 weeks. Timeline similar to retinol. Tolerability is established in the first 4 weeks (minimal redness/flaking, even on unlucky skin); Visible results are expected in 6-8 weeks.

6. Is Bakuchiol safer for sensitive skin?

   Yes. SCORAD irritation score bakuchiol 2.1, retinol 5.8 in Dhaliwal 2019 (p <0.001, significant). Bakuchiol is preferred for rosacea, atopic dermatitis, reactive skin. There is no flaking, burning or erythema like retinol.

7. Can bakuchiol be used with niacinamide?

   Perfect combination. Niacinamide barrier strengthening + sebum control; bakuchiol collagen synthesis. Same day, same routine free. Brands like Ole Henriksen offer bakuchiol + niacinamide combo.

8. Is Bakuchiol compatible with Vitamin C serum?

   Yes, but separate times are recommended. Vitamin C in the morning (UV photoprotection), bakuchiol in the evening (repair). If you want combination, fully absorb Vitamin C (15 minutes), then bakuchiol; pH compatible formulation is ideal.

9. Is swelling/redness on the bakuchiol head normal?

   rare; Reported below 1%. If you have mild erythema, start with dampening moisturizer/cold compress for 30 minutes. If persistent or allergic (hives, throat tightness), conclude that skin testing is necessary; The formulation may have cofactors (fragrance, preservative).

10. Is the Bakuchiol brand available in Türkiye?

    Limited; Sephora Turkey sells some brands (Ole Henriksen, Herbivore). International e-commerce (Sephora.com, yeeshop.com, iKlinik) can import. Dermocosmetic pharmacy brand has started but is not widespread. It is practical to order online according to dermatologist recommendation.
