i think you should try applying baby oil after taking bath,leave it for a while--then put a lavish amount of lotion..Sun exposure is a NO-NO..try using creams or whitening lotions with SPFs..try to use dove soaps,because it has moisturizers in it..taking a bath removes dirt--as well as natural oils in the body..so try to replace it with soaps,oils and creams..hope that could help you.
