I am posting this to warn others that chemical peels can cause severe and lasting damage if not done properly. I did a TCA peel on myself several years ago in my early 20s...and several years later, the damage is apparent. I have streaks/hyperpigmentation markings, indented slashes, and various scars, all over my entire face. Please, if you must do an at home chemical peel, follow proper protocol. I was young, and ignorant about the process and now I suffer for it greatly.
