<s>[INST] Hi.. My whole body complexion is becoming darker. Parts of my body not exposed to sun were very fair before. But now my whole body has turned darker and is becoming darker day by day. I would like to know what might went wrong and how to get back my previous skin tone [/INST] Hello,Thank you for posting on HCM.Generally, in my patients of sun tanning I would advise then to get series of microdermabrasion followed by chemical peeling. Microdermabrasion is a procedure that removes the superficial deas layers of skin and it is done with a help of machine. Then after a week or same day itself I would carry out another procedure called chemical peeling. Chemical peeling is again a similar procedure where superficial layers of skin is removed but here the effect is more profound and it stimulates new skin generation in much better way thus giving you more youthful and radiant skin.Several options are available in chemical peels like glycolic acid, salicyclic acid, TCA but my personal favorite is retinol peel or also known as Yellow peel.The rationale of combining these procedure is to get better and long lasting effects.I am sure 6-8 sessions will bring out a pretty gratifying results.At home the results can be maintained with antioxidant tablets like Antoxid HC once daily in morning(It can be safely taken for months together) and night application of cream containing mixture of glycolic acid , arbutin and Kojic acid. In morning you can apply a good quality sunscreen with additional skin lightening ingredients (NILTAN SPF).Use a good quality facewash like Fash facewash gel.Take plently of fresh fruits and vegetables in your diet and indulge into regular exercise for healthy skin and body.Hope this was useful.Let me know if I can be of any more assistance.Thank you and take care,Dr Hardik PitrodaM.D Dermatology </s>
