Tretinoin is the most evidence-based prescription skincare medication — a topical retinoid that accelerates cell turnover, boosts collagen, and treats acne, fine lines, hyperpigmentation, and photoaging. YourMD partners compound custom concentrations and combination formulas not available off-the-shelf.
Commercial tretinoin comes in a handful of fixed concentrations (0.025%, 0.05%, 0.1%) and a limited range of bases (cream, gel, microsphere). Compounding allows your physician to prescribe:
Tretinoin accelerates the natural cell turnover cycle from roughly 28 days to 14–17 days. This pushes newer, healthier skin cells to the surface while stimulating collagen production in deeper layers. Over months, the result is smoother texture, fewer fine lines, reduced acne, faded dark spots, and more even tone. It is the only topical with clinical-trial evidence for all three: acne, photoaging, and hyperpigmentation.
