CAS Number: 68-26-8
DESCRIPTION
What It Does: Retinol accelerates skin cell turnover, stimulates collagen production, reduces fine lines and wrinkles, fades hyperpigmentation, and helps normalize pore size.
Why It's Used: It is the most evidence-backed anti-aging ingredient available without a prescription. it provides comprehensive skin renewal benefits that no other single cosmetic ingredient can match.
How It Works: Retinol is converted in the skin to retinoic acid, which binds to retinoid receptors in cell nuclei. this activates gene expression changes that accelerate cell turnover, boost collagen synthesis, and inhibit matrix metalloproteinases (collagen-degrading enzymes).
Typically Found In: Night creams,serums,eye creams,targeted treatment products,anti-aging formulations

SCIENTIFIC NOTE
Retinol is approximately 20 times less potent than prescription tretinoin (retinoic acid) but significantly better tolerated. the conversion rate of retinol to retinoic acid in skin is the rate-limiting step in its efficacy.
