If you have had acne for 4 years and now have dark spots, you likely have post-inflammatory marks, which fade but need consistent care. If the marks are very dark or keep increasing, consult a dermatologist.

Brownish acne marks are usually post-inflammatory hyperpigmentation, and they fade with the right skincare routine. Use a gentle face wash, apply a vitamin C serum in the morning, and always use sunscreen, because sunlight makes brown marks darker. Avoid picking or squeezing pimples, and give the treatment at least 6 to 8 weeks to show visible results. Consult a dermatologist if the marks are very dark or old.

Dark patches on the cheeks that look like melasma can improve with gentle, consistent care. Start by protecting your skin from the sun every day using sunscreen. Use a broad-spectrum sunscreen SPF 30 or higher. Avoid harsh scrubbing and heat exposure, as these can worsen melasma. Consult a dermatologist for a specific treatment plan based on your condition.

To reduce pimple marks on your face, keep your skin clean and use simple treatments that fade dark spots over time. Always use sunscreen during the day, as sun exposure makes marks darker. Avoid picking pimples, drink plenty of water, and keep a gentle skincare routine. If marks are very dark or old, consult a dermatologist for treatment.

Dark skin on the knees is common and usually happens due to dryness, friction, or past irritation. You can lighten it gradually by keeping the area well-moisturised with a thick cream, gently exfoliating 2 to 3 times a week, and applying lightening creams at night if advised by the doctor. Always use sunscreen on your knees when going out, as sun exposure makes the darkness worse, and try to avoid kneeling on hard surfaces. If the darkening is stubborn, a dermatologist can help with stronger treatments.

If you have pimples and acne, keep your routine simple. Wash your face twice a day with a gentle cleanser, use a light oil-free moisturiser, and apply an acne treatment at night as advised by your doctor. Avoid picking pimples, drink plenty of water, and keep your pillowcases clean. If acne is painful, leaves marks, or keeps coming back, consult a dermatologist.
