Retinol
Vitamin A, Vitamin A1
Cell-communicating retinoid that speeds cell turnover and stimulates collagen production.
Decades of RCTs confirm retinol and its esters reduce fine lines and improve texture; tretinoin remains the gold-standard comparator.
Avoid layering with AHAs, BHAs, and benzoyl peroxide in the same session; use only at night, always with daily SPF.
Directly supports collagen synthesis and epidermal renewal for firmer, smoother mature skin.
The Science Behind Retinol
Retinol is a vitamin A derivative that signals skin cells to turnover faster and build more collagen. It is the most studied pro-aging active we have. Start twice weekly at low strength, moisturize after, and never skip sunscreen — retinol makes skin more sun-sensitive.
