CO2 Fractional Laser Aftercare & Downtime Guide
CO2 fractional laser downtime is typically 5–10 days. Expect redness and a warm, sunburned feeling for the first 1–3 days, followed by bronzing and fine flaking as treated tissue renews. Strict sun protection, gentle cleansing, barrier repair, and avoiding makeup for 24–48 hours are the core of safe aftercare.
Day-by-day
Days 1–3: redness, swelling, oozing controlled by cold compresses and prescribed ointment. Days 4–7: bronzing, tightness, light peeling. Days 8–10: pink fresh skin, makeup usually OK. Full colour normalisation takes 2–4 weeks.
Aftercare rules
Cleanse gently, apply barrier cream, avoid picking, no active ingredients (retinol, AHA) for 2 weeks, sleep elevated, and use broad-spectrum SPF 50+ strictly for 3 months. No sauna, pool or exercise sweat for 48–72h.
Red flags
Spreading pain, pus, fever or dark scarring need prompt clinician review. Pre-treatment antiviral cover may be advised for cold-sore history.
