Is chemical peel safe for the skin?

The place I am going for photo facials suggests I do a chemical peel between IPL sessions. The Melbourne skin clinic I am going to suggests packages of chemical peels and photo facials. They started me with a microdermabrasion, then a photo facial, then 2 weeks later a chemical peel and 2 weeks after that another photo facial. I am not sure of the results I am seeing yet and wanted to know if this was a normal course to get best results?

I’m 27 and about 5 years ago I ordered a TCA peel online all over 6 months. I did about 6 peels (I know way too many), and I have completely damaged my skin. I have really bad scars, especially under my eyes. I am starting to wrinkle under my eyes and my skin is just disgusting and uneven, I never had a problem with acne before. Now I wake up every day with new pimples and I have bad cystic acne, how can I repair my skin? Would dermarolling be useful? Does emu oil really thicken damaged skin?
