Best Laser to Treat Pigmentation on Indian Skin?

I would avoid the laser as this may worsen the pigment condition, and result in hypopigmentation or hyperpigmentation, both things you will not want.

If you have tried hydroquinone (fading cream) and retin-a (tretinoin), light chemical peels and sun avoidance, it may be time to look into laser treatment for your pigmented patch. We recently purchased a new Fraxel laser, called the Fraxel Dual. It has two wavelengths. The original Fraxel restore 1550 non-ablative resurfacing laser, and a new 1927 wavelength that seems to work really well for brown discoloration on ALL skin types. It is a brand new wavelength to skin treatments. I have treated 10 patients with melasma or other dyspigmentation and have had 50 to 75% improvement with just one treatment. I suggest that you continue with the fading cream as it will help a little - but look into the Fraxel Dual.

 
Deep Chemical peels and ablative CO2 and flat beam Erbium laser resurfacing and Photofacial or IPL risk causing post inflammatory hyperpigmentation when used on Indian skin.
The non-ablative fractional Erbium 1540 laser can be used safely on Indian skin when used by an experienced doctor at low power settings, to remove pigment.
Seek out a doctor who has experience treating dark skin with the laser. I use the Lux1540 non ablative Erbium laser.
