Treating PIH in Asian Skin?

Dark pigmentation on the skin can be caused by genetics, hormones,
and sun exposure. I would use a carefully curated protocol of laser
therapy, fractional ablation, Covalent peels, and topical creams. The
most important step is first starting Melarase creams for at least 6 to 8
weeks.

In experienced hands, asian skin can be treated with almost any laser, as long as the settings are titrated accordingly to the precise texture, tone, and pigment of your specific skin. In your case, I would not recommend Fraxel laser for your post-inflammatory hyperpigmentation. Though it could certainly help with other common skin issues, such as large pores, scars, wrinkles, etc, I think you may want to either wait longer for the hyperpigmentation to decrease on its own, or expedite the process with a lightening cream containing hydroquinone. You must also be vigilant about sun protection. Hope this helps. 

With most Post Inflammatory Hyperpigmentation which is brown  I suggest a home Glycolic Acid lotion program. However, your problem is red and pink. So in your case I would do a couple of tests pulses with Photofacial (IPL). Then I would wait a couple of weeks to make sure you don't have a reaction to the IPL. If you tolerate the test pulses you could benedit from Photofacial.
