one thing im confused about is regular exoderm included with the chemabrasion or is it just the peel alone. when i read bad reviews i dont know if they are talking about just exoderm or phenol chemabrasion
Exoderm is another name for a phenol peel, of which there are several types. Phenol chemabrasion uses a weaker concentration of phenol and adds the dermabrasion, so there's a difference.
It's still a pretty hard procedure to do in terms of recovery and you have a HIGH risk of pigmentation problems. According to the study ~40% of people had pigmentation issues afterwards. If you're willing to accept the risk then go for it - I'm sure it will give you as good as/better results that other treatments.
"Fulton feels that deep acne scars are best treated by combining CO2 laser with dermabrasion."
The possibility of hypopigmentation is something to take into account, then, particularly for darker skin types. I have fair skin so it's less of an issue. As for CO2 and dermabrasion, based on reviews it seems the key is to find a doctor who will be aggressive enough to penetrate deeply enough into the skin to level the depressed areas as much as possible with the surrounding skin. If the doctor isn't invasive enough, there will only be superficial results. With the phenol procedure at least we're obviously penetrating deeply -- perhaps too deeply for some people.
