I applied the TCA 25% solution, quickly and I fear not evenly. In less than 1 min. my left cheek started to frost and I had too take it off, It burned very, very, badly. My left cheek turned brown as soon as I rinsed off the solution. The procedure was done 24 hours ago. Is it normal for my skin to turn brown so fast? My right cheek bone today is brown as well. I am keeping Emu oil and A&D ointment on my face. I will start with the vinegar rinses tom. Thanks in advance for your time~
