Hyperpigmentation after chemical peel sun exposure. Will combination chemical peel or microdermabrasion help?

Thank you for your question.  You can get similar effects of microdermabrasion from doing a scrub at home.  You hyperpigmentation is much deeper.  Chemical peels will probably yield limited results.  The trauma from microneedling can actually cause more damage.  Hyperpigmentation is something we see and treat every day in our practice.  Depending on your skin type, you may be a candidate for a series of IPL treatments.  It should only be done on Skin Types I-III with no sun exposure.  Summer is probably not the best time to start IPL treatments.  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.
