If your face has acne and uneven (unfair) skin tone, you can improve it by washing your face twice daily with a gentle cleanser, using a light oil-free moisturizer, and applying acne treatments like Adapalene at night to clear pimples and Niacinamide in the morning to reduce marks and even skin tone; avoid picking pimples, limit oily and sugary foods, use sunscreen daily, and stay hydrated, and if acne or dark spots persist, consult a dermatologist for proper treatment.
