Hi doctor, i m a 25 year old female and i went to this dermatologist for active acne and she started me on isotretinoin nd combined chemical peel with salicyclic acid, my acne reduced a bit but i have developed dark hyper pigmentation on my cheek, i got really frustrated and then i checked he internet and i found out ur not supposed to combine peels with sotret. So i stopped going to the derm, rt now i m really frustrated the hyperpigmentation is worse, i stopped sotret its been a month, can u help me with this hyperpigmentation please.
