How many microns deep does laser resurfacing need to be to cause scarring?

Asked By:nearlynatural in Los Angeles, CA

I had resurfacing of eyelids a few months ago. The doctor claims it was fully ablative Erbium laser 20 microns dialled in 10 hz, and then fractional co2 core 5% 80 mj, 3 passes. Skin peeled when I gently washed off my makeup at 3 weeks. Painful to touch for a long time. Developed hypertrophic and atrophic scarring, and have had vbeam and 5fu / steroid to treat. I read 20 microns is a weekend peel depth and that is doesn't reach the dermis. Is this information consistent?
