Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain Betnovate C and although it gives good results initially but the results are not ever lasting and you get darkening of skin once the use of the creams is stopped and along with it there are also severe side effects of this cream like inflammation and pigmentation of skin, skin thinning, rashes, photosensitivity, facial hair growth, dilatation of veins under skin.. It is better to stop using this cream and just keep patience even if your face become dark and let the skin to get healed gradually.. You can apply creams containing Kojic acid as it is safe for long term use as is mushroom extract.. You can use facewash containing Salicylic and glycolic acid that helps in easy peeling away of dead cells and it will help in formation of new cells .. Creams containing Arbutin and glycolic acid should be used. Apply Vitamin E oil at night.. Take Vitamin C supplements.. Wash your face multiple times a day with cool water. Limit sun exposure as it can cause more darkening due to Photosensitivity effect of the steroid.. You can also go for photofacial, galvanic facial, chemical peeling or microdermabrasion. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora..
