hi . I was using depiwhite advanced as recommeneded by a doctor after i got hyperpigmentation after laser hair removal session in bikini area. after applying the cream for a month , i got contact dermatitis .
i applied fucicort cream for a week . the redness and burning sensation was gone . but then after another week i found that the area around the lips became red again so i applied fucicort for another week . then i stopped . now i still got a burning sensation and the area around the lips has darkened.
i put now aloe vera gel to relieve the burning sensation. what should i do ?
