Glycolic Peel for Hyperpigmented Asian Skin?

We are not big proponents of peels for the pigment you describe.
For pigment caused by sun damage, we would suggest q-stitched lasers. For Melasma (pregnancy mask) we would suggest hydroquinone bleaching programs.  Both of these programs will work better than chemical peels.

For hyperpigmented asian skin, we prefer topical creams such as Melarase followed by application of the Melapeel once monthly. Raffy Karamanoukian, Los Angeles

Glycolic peels for brown or hyperpigmented spots in Asian skin is a safe and often effective treatment. Talk to your dermatologist about this treatment, or potentially other treatment options such as cryotherapy, laser, and even topical bleaching creams, depending on the precise type of skin problem.
