Generic Retin-A Micro Gel contains tretinoin, a retinoid derived from vitamin A. This active ingredient works by increasing cell turnover, promoting the shedding of dead skin cells, and stimulating collagen production.
Mechanism of Action
Tretinoin binds to retinoic acid receptors in the skin. This binding triggers a cascade of cellular events that lead to increased skin cell renewal. The result is smoother, clearer skin with reduced appearance of fine lines and wrinkles, acne lesions, and hyperpigmentation. The “micro” in Retin-A Micro Gel refers to the formulation’s smaller tretinoin particles, allowing for better penetration and reduced irritation.
Composition Details
Besides tretinoin, the gel also contains inactive ingredients that contribute to its texture and stability. These vary slightly depending on the manufacturer, but common examples include water, alcohol, and various polymers to control viscosity and ensure even application. Always check the specific inactive ingredient list on your product packaging for potential sensitivities.
Important Note: While generic versions are bioequivalent to brand-name Retin-A Micro, subtle differences in inactive ingredients might affect individual tolerability. Consult your dermatologist before switching brands.
