Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern.. As per your complain first thing that I would like to tell you is that it is possible to improve skin complexion that is darkened due to pigmentation that can be due to causes like sunburn, side effect of any cream or ointment etc.. But the skin complexion that you have since birth or in childhood is what you have acquired genetically and it cannot be changed.. So inorder to improve your complexion that has darkened due to pigmentation, you can wash your face with Salicylic acid and Glycolic acid containing facewash.. You can apply creams containing Kojic acid, Arbutin, Vitamin E & C.. Azelic acid creams are also helpful.. You can exfoliate your skin twice a week using a gentle scrub.. You can apply sunscreen lotion when exposed to sun and also try to limit sun exposure and cover your face with a scarf.. You should also take Vitamin C supplemets.. You can go for treatments like Microdermabrasion and chemical peeling.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
