TCA peels can be very strong. Most medium depth peels take up to two weeks to see skin "go back to normal". I am a licensed esthetician. TCA peels and any peel over 10% should NEVER be performed by an untrained novice. In some staes only medical professional can administer TCA peels. There are many contraindications with peels and if you are not knowledgable about skin anatomy you can damage skin permanently. People try to save $$$ by doing it themselves and end up not getting the most benefits from the peel or worse, permanently scarring themselves or someone else. My advice if your skin does not get better is to go to a dermatologist and find out what you did wrong. Good luck.
