Quick Summary
The gold standard of anti-aging skincare — the only topical proven to reverse photoaging
Also called: Retin-A, All-trans retinoic acid, ATRA, Retinoic Acid
What is Tretinoin?
Tretinoin is the most evidence-backed topical skincare compound in existence. A prescription-strength vitamin A derivative (retinoid), it is the only topical agent with robust clinical evidence for reversing photoaging, reducing fine lines, improving skin texture, clearing acne, and increasing dermal collagen production. Dermatologists consider it the cornerstone of any serious skincare protocol. Studies show measurable improvements in skin thickness, collagen density, and elastin content within 12 weeks of consistent use (Kligman et al., 1986; Griffiths et al., 1995).
How It's Made
Tretinoin is all-trans retinoic acid, the active form of vitamin A. It is synthesized chemically and formulated in cream, gel, or solution vehicles at concentrations of 0.025%, 0.05%, and 0.1%.
