Discoloration from Erbium Laser Resurfacing

The risk of delayed postinflammatory hyperpigmentation is nontrivial for ethnic skin, e.g. Latino, Asian skin. Ideally, there should have been pre-treatment with topical retinoid and/or hydroquinone prior to laser resurfacing for ethnic patients. The good news is with appropriate medical treatment by a board-certified dermatologist experienced with ethnic skin, the pigmentation typically will improve in 2-3 months. Q-switched Nd:Yag laser such as Spectra laser can be considered as the new gold standard for post-inflammatory hyperpigmentation.

It is not clear if you are having post-inflammatory pigmentation or less likely-a provocation of melasma. There are many excellent treatments which dermatologists know. These include topical creams with Berry, soy, azelaic acid, mild steroid creams, Vitamin C, Kojic acid etc.

From your history I assume you had flat beam Erbium laser resurfacing.
Newer fractional Erbium laser resurfacing is less likely to cause post inflammatory hyperpigmentation.
I agree with the use of topical bleaching regimes mentioned below and microdermabrasion.
If the pigment is not removed after 2-3 months of topical skin care there are other alternatives.
Low intensity non-ablative 1540 fractional Erbium treatments can help.
