I had a tca peel and now my face us very red after the old skin peelled off. Is this normal

What percentage did you have applied to your skin?
Redness can be part of the peeling process and usually wears off after a while and make sure you use a very good moisturizer preferably one with not too many active ingredients or scented because that can sting.

Redness is perfectly normal. It'll fade back to normal in just a few weeks and you'll look great.
