Aha bha exfoliate dark spots

Start by clarifying your skin type, the severity of the spots, and your tolerance for irritation. AHAs like glycolic acid target surface texture and pigmentation, while BHAs like salicylic acid help with oily or clogged pores. For sensitive skin or first‑time use, opt for lower concentrations and gentler formulations such as toners or serums. Remember to wear sunscreen daily to protect new skin after exfoliation.

Concentration and pH determine how strong the exfoliation will be. A lower pH increases acid activity, and higher concentrations deliver deeper exfoliation but raise irritation risk. For beginners, start with milder options and gradually build tolerance, especially if you have sensitive or reactive skin. Always pair with sunscreen during the day to protect new skin.

Beginner users with sensitive skin should start with a mild formulation and patch test before increasing frequency. Experienced users can handle higher strengths, may layer with moisturizers to minimize irritation, and can adjust frequency based on tolerance. Avoid using multiple strong actives at once and stagger application times to reduce irritation. Build a routine that suits your skin, not the other way around.

Patch test a small area for 24 to 48 hours before full use. Apply after cleansing and before moisturizer, and limit use to evenings. Always wear sunscreen during the day when you exfoliate. If you experience burning or persistent redness, slow down or discontinue use and consult guidance from a dermatologist.

Look for formats that fit your routine, such as serums, toners, or creams that carry AHAs or BHAs. Choose fragrance-free formulas if you have sensitive skin and select reputable brands known for skincare actives, such as The Ordinary, Paula's Choice, or La Roche-Posay. The format you pick should match how you prefer to apply the product and how your skin responds to ongoing use.

If you notice persistent irritation, burning, or redness, stop using the product and consult a dermatologist. If there is no improvement after several weeks, or if spots darken or spread, seek professional advice. Avoid aggressive or unsupervised mixing of actives, and adjust your routine under medical guidance. A professional can assess whether to combine treatments or explore alternative options.
