Reducing redness after treatment comes down to staying out of the sunlight and wearing broad-spectrum sunscreen for several weeks before and after a CO2 laser procedure. You should keep applying that sunscreen for three months after your procedure. Think of it like a maintenance period. If you end up exposing yourself to too much sunlight then you risk that redness turning into hyperpigmentation or darkening of the skin. If redness after your resurfacing procedure is your biggest concern because you have a vacation or event coming up, we can always perform the treatment on lighter settings with the understanding you’ll have more of a short-term improvement.
