Hi Doctor, I am 27 yrs female , 5.4 height and 68 kg s weight. I have notices that due to in growth in my bum cheeks, I have faced dry skin and marks in the whole area. Although it does not itch or hurt. But, it looks really ugly. I have consulted a derma and she has suggested me to apply retina AC cream. Is that cream effective because she siad marks will reduce in 4-5 month of time but she didn t tell me whether they will completely go or not. Could you please suggest?. Thanks and Regards, Patient
