Postinflammatory hyperpigmentation and Melasma can be treated with a combination of treatment modalities.
Hyperpigmentation can be very difficult to treat especially in type IV through VI skin types. Aggressive treatments sometimes make the problem worse. For those patients that do not responds to simple treatments with bleaching agents, the best treatment that I use is the Cosmion Iontophoretic Mask with a preservative-free gel containing, Ascorbic Acid, Phytic Acid, Arbutin and enzyme. I often combine this with a gentle nanosecond 1064/755 laser or PicoSure 755 fractional or full-beam treatment to break up the pigment. On some cases, I use the Fraxel Dual Laser or the Palomar 1540nm Laser. Not all abnormal pigment responds well to the same treatment. Epidermal melasma responds differently that dermal melanoma. It is critical to always use a shoulder-to-shoulder hat, an excellent UVA/UVB sunblock like Laroche Possay Anthelios 60 and a good bleaching agent such as Obagi Nuderm especially while undergoing treatment.
Hyperpigmentation and chemical peels
Chemical peels can be a great option for reducing some causes of hyperpigmentation such as sun spots, sun damage, melasma, and post-inflammatory pigmentation. It is important to see a physician to be evaluated as to the cause of the pigmentation prior to initiating any therapy. Caution should especially be advised in patients with melasma as incorrect chemical peels can exacerbate the problem. See a Board-certified dermatologist for evaluation of the brown spots as these could be age spots known as seborrheic keratosis which would not respond to topical therapies.
Pleas post a photo to help you. It sounds as if you have Melasma which would definitely get worse from lasers. I would recommend you seek an expert in the field of cosmetic dermatology and consider chemical peels or Cosmelan treatment. Best, Dr. Green
