To treat both active pimples and the dark spots they leave behind, you can use targeted over-the-counter active ingredients. For acne, look for a gentle face wash containing salicylic acid to clear pores, or a gel with benzoyl peroxide or adapalene to apply directly to pimples. For the dark spots, creams containing azelaic acid or niacinamide are excellent because they gently fade pigmentation while preventing new breakouts. Always apply a broad-spectrum sunscreen daily, as sun exposure can worsen dark spots. Introduce these products gradually to avoid irritation, and consult a dermatologist if your condition persists.
