Understanding and respecting the Pico laser aftercare 72-hour rule is vital for optimal skin healing and visible results. The first three days post-treatment mark a critical phase of inflammation control and tissue regeneration. Gentle skincare, strict sun protection, and avoiding irritants help preserve the laser’s benefits and prevent complications like hyperpigmentation or infection. With proper aftercare, users can achieve clearer, smoother skin and extend the results of their Pico laser treatments.
