The Gold Standard in Dermatology

Tretinoin (all-trans retinoic acid) is a highly potent prescription retinoid. It is clinically recognized as the gold standard for treating photoaging, fine lines, acne, and uneven skin texture.


How Retinoic Acid Rejuvenates Skin cells

Tretinoin works by interacting directly with retinoid receptors in your skin cell nucleus:

  • Accelerated Cell Turnover: Speeds up your skin's natural shedding cycle from 28 days to roughly 14 days, clearing dead skin and unclogging pores.
  • Collagen Synthesis: Stimulates fibroblasts to produce new collagen and elastin fibers, increasing skin thickness and elasticity.
