A-Ret 0.025% Gel is a widely used topical formulation for mild to moderate acne. Its principal active ingredient is Tretinoin—a derivative of Vitamin A—known for its powerful effects on skin cell behavior. Tretinoin unblocks pores and allows oil glands to function properly, decreasing the formation of blackheads and spots. It also improves skin texture, reduces acne, and minimizes fine lines and wrinkles. Tretinoin should be applied carefully with proper techniques and precautions. It also hastens the speed at which surface skin cells are replaced and aids in the dispersion of pigment (melanin).
