Skin discolouration

The skin on my buttocks and under my breasts is becoming darker due to the friction from panties and bra. Kindly help to improve my skin colour.

 

The discoloration could be due to constant irritation or an allergy to somecomponent of the underwear. I would suggest wearing pure cotton undergarments for a few months and see if your skin color improves. Also, do not wear very tight fitting undergarments. You may try over the counter 1% hydrocortisone cream. If none of these work, please see a dermatologist.
