For those seeking the highest level of potency, this prescription cream offers the most concentrated form at 0.1% for robust treatment of acne, hyperpigmentation, and early signs of aging. The active ingredient, tretinoin, is derived from Vitamin A in the form of retinoic acid and is renowned in the skincare industry as one of the most visibly effective treatments available. It mirrors the same type of Vitamin A naturally synthesized by the body for skin health and other vital functions. Tretinoin operates deep within the skin's layers, stimulating collagen production, regulating pigment production, and addressing the root causes of acne. Noticeable improvements are typically seen after consistent use for 6-12 weeks.
