I am suffering from hyperpigmentation after CO2 laser for stretch marks

Hyperpigmentation can be improved with a combination of Cosmelan, lasers, Aerolase, microneedling/prp, skin lightening, peels, and skin care. Sun protection is essential. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

Thank you for your question.  It sounds like you might have Post Inflammatory Hyperpigmentation (PIH).  It may fade on its own over time.  Topical fading creams may also help.  We have been very successful using the PicoSure laser with the FOCUS and / or Flat Lenses eliminating hyperpigmentation with a series of treatments.  FOCUS lens treatments have the extra benefit of reducing stretch marks.  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.  I hope this helps.
