Can Exposure To Sun Cause Any Problem During Facial Neoderma Bio Peeling?

hi i am doing a facial Neoderma Bio peeling. I live in Cyprus which is very hot 24/7 and the sun is very strong. I am under a treatment which involves 12 sessions once every week. I asked by beautician and she said she guarantees that since it is bio the sun cant do any harm. I am worried however still since my face "exfoliates" (i dont know the exact expression- dead cells are removed). Please advice as i am in the middle of the treatment and i was told that if i stop now my spots will become worse than before i started it.

Please advice! Thank you very much in advance!!!!
