A Ret 0.05% Gel works by delivering Tretinoin, a vitamin A derivative, deep into the skin where it speeds up cell turnover and promotes the shedding of old, dead skin cells. This helps to unclog pores, reduce acne breakouts, fade dark spots, and stimulate collagen production, which improves skin texture and reduces fine lines. Over time, it leaves the skin looking clearer, smoother, and more even-toned.
