This product changed my life!  I have a lot of shallow scars, a few boxcar scars, and a lot of hyperpigmentation from old scars. I have tried dermaneedling for two years and didn't see much change and was going try laser resurfacing it but sounded too risky and expensive (since I didn't want to damage my the good parts of my skin).  I didn't think chemical peels would make a huge difference so I never thought much of it until I stumbled upon reading about different peels online. I bought and used the glycolic acid 40% two weeks earlier and that didn't do anything but make my face more smooth the next day.  I decided to try purchase the tca 20%  and and see if it would make a difference. I was hesitant after reading stories of people having bad experiences with tca peels but I finally got up the nerve to try it.  I have asian skin and read I should be more cautious which is why I stuck with 20% and nothing higher.  It wasn't bad at all compared to the burn with the glycolic acid 40% for some reason (maybe it prepped my skin)!<br /><br />I applied it after meticulously cleaning my face with diluted rubbing alcohol (to make the alcohol fumes more tolerable).  I then applied this product for about 3 minutes and only got to really light frosting and didn't continue with another layer since for my first time I wanted to be on the safe side. My skin got really tight feeling but wasn't red.  The next morning it didn't really look at all different than before I did the peel.  Since I only had one week before work started I didn't have much time to wait it out a week or so and see the results which I felt weren't going to be dramatic because I didn't really get a good frost.  I decided to apply the peel again the next afternoon (I researched and was convinced it was ok since I know my skin well and knew I could handle it--not everyone can handle this so this is not suggested!!) I left it on for the full 5 minutes and it burned more than the previous night. I also frosted morethan the previous night (but not completely white) and could see my scars turning a little red so I neutralized and rinsed with water. Surprisingly the second time it did not feel as tight. I applied aquaphor (kept it moist for at least 8 hours at time) for a week while it peeled and didn't have any discomfort. My skin turned darker during the healing process but looked fine otherwise. The fun part was to see it peel and see the fresh skin underneath.<br /><br />The edges of my shallow scars have softened and the hyperpigmentation is still there but has lightened in some areas. My skin looks so much more refreshed and softer.  This is the first time in the past fifteen years that I feel confident not wearing makeup. I'm only using some tinted sunscreen as a moisturizer and concealer in two or three spots.  I plan to do this peel in another two months. Cannot wait to the see the results! The scars haven't completely disappeared but it gave me a second chance and most of all taught me to not pick at my face so I don't ruin my results! So happy with the results so far. Life changer!
