Can Erbium fractional resurfacing make a red surgical scar worse?

I'd like to speed up my surgical scar healing and have an appt for YAG Erbium resurfacing. The scar still has some redness and I've been advised by a dermatologist to wait until the redness completely resolves. I know CO2 ablative laser could make it look worse if there is still PIE redness, but is this also the case with Erbium fractional laser? As the scar is facial I want it to resolve asap as I'm very self conscious about it, but I also don't want to make it worse.
