StemFactor Growth Factor Serum

Hyped exosome gimmick with unproven concentrations and irritating lemon oil that doesn't justify the premium price. Efficacy score of 2.8 calculated from promising growth factor media (Human Stem Cell and Fibroblast Conditioned Media) claiming 600+ factors and 2.8 trillion exosomes per bottle, but massive deductions for unknown concentrations (listed mid-formula after water), lack of clinical concentration data, no encapsulation proof beyond marketing, and suboptimal water-based formula without pH stabilizers for growth factor stability; lemon oil risks irritation without synergy bonuses like Vitamin C+E+F.[2][5][9] If you're looking for vegan skincare, this is worth evaluating.

This is a fragrance free skincare formula, making it suitable as fragrance free skincare for sensitive skin. no S Tier gold-standard actives were detected. Benzyl Alcohol is present — a formulation-base ingredient with rare sensitisation reports, not a documented irritant.

OSMOSIS StemFactor Growth Factor Serum has a safety score of 4.2/5. The only ingredient flagged is Benzyl Alcohol, a formulation-base ingredient with rare, low-frequency sensitisation reports. It is not a concern for most people, but worth knowing if your skin is reactive. As a fragrance free moisturiser suitable for sensitive skin care, it avoids common triggers for reactivity.

Based on its formulation, OSMOSIS StemFactor Growth Factor Serum is best suited as a moisturizer for sensitive skin.

DemythSkin recommends: SkinMedica TNS Advanced+ Serum — Clinically proven growth factors at optimized concentrations with peptide synergy, superior stability.. NeoStrata Bioactive Skin Repair Serum — High-efficacy growth factors and antioxidants in stable formula, better value without irritants.. The Ordinary Multi-Peptide + EGF Serum — Affordable peptide/GF blend mimicking repair without unverified exosome hype or fragrances..

Based on DemythSkin's INCI analysis, no fragrance, parfum, or essential oils were detected in OSMOSIS StemFactor Growth Factor Serum's formula. This makes it a strong candidate as a fragrance free moisturiser for dry skin or fragrance free skincare for sensitive skin care routines. Always cross-check the current label as formulas can change.

DemythSkin scores every product out of 5.0 on two separate axes: Efficacy (does the formula deliver its claims?) and Safety (will it irritate?). Ingredients are graded S Tier (gold standards, high clinical proof), A Tier (reliable), B Tier (supporting), C Tier (overhyped | marketing) and D Tier (documented irritants — added fragrance, drying alcohol, essential oils). Preservatives, emulsifiers and thickeners are shown as formulation base and count as neither good nor bad.
