hi  You seem to have developed acne .  Before coming to the exact treatment, I would like you to follow certain precautions:  1. Avoid using any oily creams or lotions over face as much as possible. You can however use oil free moisturizers.  2. Wash your face frequently inorder to keep it dry . 3. Drink plenty of water . 4. Try to avoid eating dry fruits.  5.Avoid touching or squeezing of pimples.  6. Avoid Hair oil . 7. Always use a sunscreen (SPF 26) when going out in the sun.  Now as far as your condition is concerned, I would advise you might need to apply some antiacne medications like Clindamycin gel over the affected area twice a day.  You might need a systemic agent also to control acne ,so if the above medicines do not help you much, then see a dermatologist for the same. Your second problem is that of skin pigmentation due to tanning. Topical medications can definitely be of help to you in reducing the pigmentation to some extent. I would advice that you should use a lightening agent like kojic acid and vitamin c combination over the affected areas. This is a simple, harmless lightening agent which can be used for as long the blackish pigmentation is there. Also ,try not to touch the area too much.  Also ,try not to touch the area too much  Use proper sunscreen (spf 26) before going out in the sun so that the lesion doesn t darken any further  Take a diet rich in vitamin C and antioxidants like Citrus fruits and lots of salads  If after all the above measures, the pigmentation tend to persist, then i would advise that you should see a dermatologist as there are various other measures for the treatment of pigmented skin like the use of chemical peels, dermabrasion etc which a dermatologist can decide according to the type of scars..  Hope it helps  Dr Geetika Paul  MD ( Dermatology)
