After CO2 laser treatment, it usually takes about 1 to 2 weeks for your skin to heal. Your skin will be sensitive during this time. So liberal use of sunscreen, moisturizer, and strict sun protection is a must. Don’t use saunas, swimming pools, baths, or hot tubs, and avoid shaving over treated areas for the next week. Avoid applying glycolic acid, retinols, salicylic acid, and similar medications for 1-week post-procedure. Use mild cleansers to wash your face and avoid touching the treated area again and again.
