Please for the love of god don't start with anything higher than 12.5%. One bottle of the 12.5% will last you 4-5 peels. Spread them out about 2-3 weeks apart, no sooner. Understand that it isn't an instant cure. You're putting acid on your face, so your skin has to regrow and all that. I didn't really notice results until my 3rd peel (of the 12.5). In my opinion (been an acne sufferer for years, now just deal with scars and occasional blackheads), tca peels are a LONG TERM treatment. You dont just buy a bottle, put some on, and expect results. I plan on doing several peels over the next year. You have to think long term if you are looking for dramatic results. You can speed this up by going higher %, but youll have the flaking, peeling, horrible downtime that people talk about. I have a job so I can't hide for 3 days at a time. With 12.5, you dont get this, but it obviously takes more treatments to get the desired results..

Pros:

• It does even out your skin, period. Its an acid, its not like there's much room for it to not work. Over time, will reduce scarring, period.

Cons:

• Slight down time (for higher concentrations) and the possibility of not following the instructions and messing your face up. Can't be in the sun for 2-3 days after for risk of serious burning. (they aren't kidding about this, even @ 12.5%
