For the first few days after your treatment, your skin will begin to flake and peel. Your face may also feel tight, hot and slightly red. Post-treatment, avoid sun exposure and make sure to use a broad spectrum SPF. It is also best to avoid other treatments or procedures (including peels, facials, or microdermabrasion) on the treated area for 30 days. While maintaining on Cosmelan homecare, discontinue its use for 5 days before waxing, and do not restart treatment until 3 days after waxing.
