Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern.. As per your complain it seems that there is post inflammatory hyperpigmentation due to continuous inflammation caused by bleaching cream lading to formation of pigmented scars.. The first thing that you need to do is to completely stop using the bleach as it is very high in chemicals.. You should apply depigmenting creams that are not harmful and suitable for long term use like creams containing Kojic acid glycolic acid and rbutin.. You can also use azelic acid creams and vitamin E lotions or gels.. Take Vitamin C supplements.. You should also avoid sun exposure as it can lead to Photosensitivity and darken the scars.. You can also apply a sunscreen lotion when exposed to sun.. Use mild facewash to wash your face and salicylic acid preparations are helpful.. Exfoliate your skin weekly with gentle scrub.. Drink plenty of water.. You can also go for regular facials, chemical peeling and microdermabrasion and dermal rollers.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora..
