Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that the pimple spots are due to post inflammatory hyperpigmentation, secondary to pimples and the treatment that can be done is a combination of topical depigmentation creams and certain techniques.. As far as chemical peeling is concerned it is a commonly employed technique to reduce pigmentation and you need to consult a Dermatologist who will assess your skin conditions and will advise you accordingly.. You can start washing your face with Salicylic acid and glycolic acid containing facewash.. You can apply creams containing Kojic acid, glycolic acid and arbutin.. Vitamin E and C containing creams can help.. Creams that are rich in licorice extract and grapeseed extract can be helpful.. Always apply a sunscreen lotion to reduce photosensitivity effect.. You should exfoliate your skin twice a week with a gentle face scrub.. Treatments like chemical peeling, Photofacial, Microdermabrasion, dermal rollers etc can be helpful.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
