question: Hello Doctor, am 20 years old, am having a big problem with my skin, am a dark girl but my thighs are full of dry patches, pigments i would say, that turn to white when sratched.They dont itch in any way but make me feel uncomfortable. They normally tend to reduce when i use an anti-dry cream but eventually come back when usage is stopped. Please help me out in anyway and give me a solution that will help me get rid of them entirely so i can have a smooth skin thruoughout. My other body parts are very smooth with no pigments, no acne.Thank you very much
