I had the "whisper" erbium nonablative laser peel done twice the last 2 months. The first one involved hardly noticeable heat feeling, no redness and mild peeling for one day. I was not pleased with the minimal results and the spa agreed to do it over for free.
The second time was moderately hot and I turned very red the 2nd day. 3rd day I had an onion peel skin and blotchy. 4th day I peeled a lot and looked very crinkly and make up made it look worse. I peeled until the 6th day and redness gone. Results were minimal. Not tighter, not much improvement on wrinkles or brown spots. I think a cheap peel would have done the same. I used expensive creams the whole 2 months and that may have improved my skin.
The pros: it can help people under 40 or with oily acne skin.
The con is the one week down time, won't remove blemishes, minimal wrinkle improvement, no tightening.
