Does tanning before Fraxel result in hyperpigmentation?

You need to wait at least a month after sun exposure to do any laser.  The reasoning is that the sun creates inflammation and the laser does as well.  Those two together can increase your risk of pigment changes or a burn. We usually apply a small amount of Vit C serum after laser, but certainly not a whole bottle of anything.  Good luck with your treatment.

As instructed by your Specialist, tanning is not a good idea before any laser either Fraxel, microneedling or other energy based devices. Avoid 4 weeks before and 6 weeks after. All the best, Dr Davin S. Lim, Laser dermatologist. Brisbane Australia.
