After a CO2 laser treatment, healing usually follows a predictable timeline. Day 1–2: skin is red, swollen, and may feel warm or tight. Days 3–5: peeling, crusting, and flaking begin as damaged layers shed. Days 5–10: most crusting resolves, but redness and sensitivity persist. By 2–3 weeks, new skin starts looking smoother, and pigmentation evens out gradually over 4–6 weeks. Daily care includes gentle cleansing, frequent moisturization, avoiding sun exposure, and using prescribed ointments or barrier creams; harsh scrubs, makeup, or active acids should be avoided until fully healed. Consistent sun protection afterward is essential to maintain results and prevent hyperpigmentation.
