<s>[INST] Hi I m a 21 year old black male from Germany, and I have some questions concerning my skin problem. Sadly after my puberty , I have noticed that my face became 3 shades darker than the Rest of my body. I have tried many health products to cleans my face, but all failed to recover my skin. My question is, do i have some kind of health disease? Cause its only face that became much darker [/INST] Hi..thanks for your query. You don not seem to suffer from any health disorder.You can follow the steps below to lighten your skin tone by a few shades: 1)Use a sunscreen with SPF more than50 2)Take oral vitamin c supplements and antioxidants 3)Apply a mild Glycolic acid based or Kojic acid based skin lightening cream every day. 4) Take chemical peels like Glycolic Acid peels every 15-30 days.These are latest and safest methods of skin lightening when done under the supervision of trained dermatologists.They frequently produce optimum results after 4-6 sittings. hope this helps. take care! </s>
