I can't help from experience as I've never had fraxel but anything that traumatises your skin could have the potential to flare up acne. I have read of people getting blister like spots after fraxel, maybe your skin is too sensitive for the treatment? I know when I exfoliate to often and use harsher products on my skin that I tend to breakout more, your skin needs a lipid barrier to function properly and striping the skin of this can allow bacteria and irritants to flare up skin conditions. Try and stay calm I know it can be a frightening time when your skin has a major flare up, don't do anything further that will aggravate your skin and try to keep your skin as hydrated as possible. I find a bottled water spray like Aveene or Evian can help calm down redness and a good, basic moisturiser like e45, something with an emollient in it to keep in the moisture, the aquaphor is probably a good choice. It could also be the vinegar as it is acidic so will be exfoliating your skin and anything underneath will be coming to the surface, maybe try and dilute the vinegar more so it has less of a exfoliating effect on the skin. I hope things calm down soon x
the reason fraxel causes acne is that it brings all the oil to the surface of the skin. i've had a few of these treatments and the last one i got i had a ton of whiteheads pop up on my chin where i am the oiliest. the place i go to has me wash my face with my regular cleanser then use witch hazel toner to exfoliate the skin then after that i put on hydrogel and lastly ceramide cream. i do that 2-3 times a day post fraxel until my skin is healed.
also i start taking antibiotics 2-3 days before and stay on them about 7 days post fraxel. this really helps me not get any cystic acne breakouts.
one thing to note is that while your skin is healing do not pick touch or pick at any of the acne bumps because you could cause further scarring.
good luck to you and i hope you heal fast!
Thank you both so much for the information and suggestions! I called my dermatologist this morning but he didn't sound too concerned - said I could come by to see him Saturday morning. I'd really feel better with some antibiotics, hopefully I can convince him to prescribe some on Saturday and that it won't be too late to prevent a breakout. Whiteheads are still popping up like crazy today, I hope it stops there and doesn't turn into cysts.
