After mild chemical peel, I forgot to put on sunscreen the 1st day but was indoor the whole time. Is my skin permanently damage?

Hi, I got a mild chemical peels a few months ago. I completely forgot to put on sunscreen the first day but I was working at home in a computer the whole day without no exposure to direct sunlight . I didn’t realized it until the evening that I missed this very important step. Could I have permanently damage my skin? I am asking this question now because I started to.m noticed a lot of fine lines in my lower check when I smiled and they were never there before. I am 42 years old. Thanks so much
