Therapeutic skincare distinguishes itself by using active ingredients at studied concentrations, with consistent daily use being as important as product choice. For dry or sensitive skin: look for ceramides and colloidal oatmeal. For blemish-prone skin: zinc-based and salicylic acid formulas. For uneven skin tone: niacinamide, azelaic acid, and vitamin C. Introduce new active products gradually to allow the skin to adjust, and give products at least four weeks before assessing results.
