22 year old, my hands are super wrinkly as if dehydrated. I’m planning to get a chemical peel, is that right?

Thank you for your question and posting a picture.  Chemical peels will probably yield limited results.  Hyperpigmentation is something we see and treat every day in our practice.  We have been very successful using the PicoSure laser with the FOCUS and / or Flat Lenses with a series of treatments.  FOCUS lens treatments have the extra benefit of reducing fine lines and wrinkles.  Unlike the other treatments mentioned below, the PicoSure as almost no downtime.  This is one of our go to treatments for patients older than 40 and worried about the signs of aging.  This laser is safe for all skin types.  Start with sunscreen every day!  Once you have treated your hyperpigmentation to your satisfaction, you will probably need a follow treatment every 6 to 12 months depending your level of re-pigmentation.  Best of luck.
