Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain acne can occur due to a number of causes like oily skin, clogged pores, bacterial infection, inflammation and hormonal imbalances.. The acne marks seems to be due to post inflammatory hyperpigmentation caused after resolution of pimples.. I would suggest you to consult a Dermatologist and get evaluated and a thorough clinical evaluation and investigations can be advised.. You can be advised to start washing your face with Salicylic acid and Glycolic acid containing facewash.... You can be advised to apply creams containing Benzoyl peroxide and Clindamycin.. You can also apply Adapelene gel at night.. Do cool compresses over the pimples.. Exfoliate your skin twice a week with a gentle scrub.. For scars you can apply depigmentation creams containing Kojic acid, glycolic acid and arbutin.. You can also apply Vitamin E gel.. Take Vitamin C supplements.. In case if there are deep scars like deep craters or holes on face you can get for treatments like Microdermabrasion, dermal rollers, excision with elevation etc depending upon type of scars.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
