I had a few chemical peels 20 years ago which went well. I am looking to get CO2 laser resurfacing next year with the Lumenis Ultrapulse for acne scars, lines and a better tone. However the last year or two my face tingles and feels sensitive and I seem to have aged all of a sudden. I have been using salysic acid, tea tree oil, vitamin c and retinol. Unknown to me I may have damaged my ph level. Can I still get CO2 laser in the future? Can I do anything over the next year to prepare my skin?
