Pimples and dark skin can be caused by acne, sun exposure, or clogged pores. Keep your skin clean, use a gentle cleanser, and apply sunscreen daily. Eating a balanced diet, staying hydrated, and consulting a dermatologist for proper skincare can help improve skin tone and reduce pimples.

Acne can recur due to hormonal changes, oily skin, stress, diet, or irregular treatment use. Some treatments control acne but do not permanently remove the root cause. A long-term, consistent plan guided by a doctor is often needed.

Black spots after pimples happen due to leftover pigmentation in the skin. Regular sun protection and gentle skincare can help them fade over time. A doctor may suggest specific creams or treatments if the marks persist.
