Welcome and thanks for posting your query to HCM.
It seems you have three problems dark skin, super-added with tanning
. Your doctor has rightly prescribed you clindamycin
and Retinoic acid
cream. But along with it you can use glycolic acid
and azealic acid creams under dermatological guidance. These will help you out in your all the three problem enumerated. Both glycolic acid and azealic acid creams are present in low and high strengths, so try using low strength first and then gradually can shift over to higher strength. On continuous usage of 3-4 weeks will give you visible results. These are safe for long term use also.
Do not to touch or squeeze and pinch your pimples as is one of the most common cause of deep scarring. Use best sun protection in form of umbrella or covering your body.
Besides this, use a water based sunscreen 2-3 times a day half an hour before moving out. Eat a lot of fruits, green leafy vegetables and salads which will act as natural sunscreen ( best for you) and drink at least more than 10 glasses of water per day
Hope this information will help you
