30% TCA Facial Patch Test

I did a patch test with a 30% TCA chemical peel solution because I want to do a deep peel in a couple of weeks, but I need to see how a large area of my facial skin will react to this high a percentage of TCA chemical peel. 

After cleansing with Cetaphil (no alcohol prep this time) I swabbed three quick layers on one temple where my hair always falls so I can do the patch test without downtime. I let the solution work for one (1) minute, then I applied shea butter. I followed it about 15 minutes later with a very thin layer of Cu3 complex. 

Surprisingly, it didn’t hurt at all until about 20 minutes after the application! And then it HURT! So, I had to find out why. This is what I found on the John Hopkins Medical site

“Anesthesia is not usually required for TCA peels because the chemical solution acts as an anesthetic.” This makes total sense now: I’d wondered why my 50% spot treatments didn’t hurt…

Here are pictures from before to after the 3rd layer of 30% TCA chemical peel application.  I’ll post more pictures this week as it progresses.
