Blackheads and whiteheads occur when pores become blocked with oil and dead skin cells. They are common on the nose and chin and are not usually serious. Do not squeeze or pick them, because this may cause infection and scarring. The safest approach is gentle and regular skin care. Wash your face twice a day with a mild cleanser and avoid harsh scrubbing. A product containing salicylic acid can help clear blocked pores over time. A topical retinoid, such as adapalene, may also reduce new spots, but should be used as advised. Choose skincare and makeup labelled as non-comedogenic to avoid blocking pores. Avoid oily creams and wash off sweat after exercise. A balanced diet with less sugary food may help. If the problem persists or worsens, consult a dermatologist for more advanced treatment options.

Persistent pimples and dark marks on the face and back can happen when acne remains active for a long time, pores stay clogged, or the skin gets irritated from repeated breakouts, sweating, oily products, stress, or hormonal changes. Sometimes using multiple creams together without proper guidance can also irritate the skin and make marks take longer to fade. Tretin and skin-lightening creams may help some people, but improvement is usually slow and depends on the type of acne and skin sensitivity. Treatment should be taken only if prescribed by your doctor. A dermatologist may suggest a different acne routine, medicated face wash, chemical peels, or other treatments if current products are not helping. Try to wash the face gently twice daily, avoid squeezing pimples, keep pillow covers clean, and use sunscreen regularly because sunlight can darken acne marks further. Reducing oily junk foods, sleeping well, and managing stress may also support skin healing. If acne becomes painful, leaves scars, or keeps spreading, it is better to get a proper skin evaluation.
