The gold standard retinoid. 50+ years of evidence for anti-aging, acne, hyperpigmentation, and skin texture. The one product dermatologists actually use themselves.
Tretinoin (all-trans retinoic acid) binds to retinoid receptors in the nucleus, directly modifying gene expression to accelerate cell turnover and stimulate collagen synthesis. It's not a symptom mask—it literally rebuilds skin at the cellular level.
Tretinoin has the most robust evidence base of any topical anti-aging ingredient. Five decades of clinical research consistently demonstrate efficacy across photoaging, acne, and pigmentation.
Consult with a dermatologist to start tretinoin therapy tailored to your skin.
