Co2 laser is safe in the right hands. You have to go to someone very experienced for treatment. There are many other options including microneedling and fraxel as well. See an expert for treatment. Best, dr EMER.
Co2 laser can certainly be done on Asian skin if preformed by the right person. I recommend that you have a consultation with either a facial plastic surgeon or a dermatologist with Co2 experience.
Please keep in mind, that depending on the severity of the scarring there is also less evasive options that you can use as well. For example: Erbium pixel resurfacing.
It can be done, but be sure that you seek consultation with a facial plastic surgeon, plastic surgeon, or dermatologist with laser experience. In general Asian patients carry a higher liklihood of developing postinflammatory hyperpigmentation (darkening of the skin following treatment). Because of this, there are certain ways to prepare your skin in the weeks prior to treatment, certain settings that need to be adjusted on the laser during the treatment, and different ways to care for your skin post-treatment. As an alternative, there are different resurfacing modalities including peels and dermabrasion, but I would caution you about pigment changes with any resurfacing treatment. I wish you well!
