Comprehensive Guide to CO2 Fractional Laser Aftercare
Frequently Asked Questions
When can I wash my face after CO2 laser treatment?
You should avoid washing your face for the first 24 hours unless specifically instructed by your provider. After 24 hours, you may gently cleanse the skin with sterile saline or a mild, non-foaming cleanser like Vivier HEXAM. Avoid scrubbing, hot water, or washcloths.
When can I start using makeup again?
Most patients can resume wearing makeup around day 10, once peeling has fully stopped and the skin has re-epithelialized. Only use mineral-based or non-comedogenic makeup to avoid irritation. Always check with your provider first.
Is peeling and flaking normal after CO2 laser?
Yes. Peeling and flaking typically begin around days 3–5 and may last until day 7–10. This is a natural part of the skin renewal process. Do not pick or peel the skin manually, as this can cause scarring or pigmentation issues.

When can I go back to the gym or exercise?
Avoid exercise and any activities that cause sweating for at least 5–7 days post-treatment. Sweat can irritate healing skin and increase the risk of infection. Only resume physical activity once your provider has cleared you.
What should I do if I experience redness or swelling for more than a week?
Mild redness can persist for up to 2–4 weeks, especially in fair or sensitive skin types. Swelling typically resolves within the first few days. If redness worsens, becomes painful, or is accompanied by discharge or fever, contact your provider promptly.
Can I go in the sun after my CO2 treatment?
Absolutely not in the first 7–10 days, and ideally not for several weeks. Direct sun exposure can cause hyperpigmentation or delayed healing. Use SPF 50+ daily starting around day 7 (or when your provider approves) and wear protective clothing and hats when outdoors.
