There can be several causes why your skin would turn dark or you may get pigmentation. Sun tan, overweight, pigmentation disorders like acanthosis nigricans or melasma, nutritional deficiency etc are some conditions. Unless someone examines you, we cannot know the cause. Unless we find out the cause it is difficult and pointless to treat. Please send photos with detailed history using online consult option for examination and proper treatment.,

Hello , I would suggest going In for chemical peels in combination with Q switched Nd Yag lasers. Combination treatments only will work for lightening the skin and dark circles especially . At Dr Karishma Aesthetics, we also do Eye Cell Repair serum infusions with microdermabrasion which could help. Once a week sittings are done with home based Vit C creams .

Undergo glutathione therapy.... Otherwise, few creams also available.. contact me by direct online consultation for treatment.
