Timing depends on the laser depth, whether the rhinoplasty was open or closed, skin type, swelling, and incision healing. Fully ablative or aggressive fractional CO2 treatment is generally deferred for several months, often at least 3 to 6 months, and longer if redness, swelling, numbness, or skin compromise persists. Gentler nonablative treatments may sometimes be considered earlier. Obtain clearance from your treating rhinoplasty surgeon before any energy treatment on the nose, and have an experienced dermatologist or laser specialist choose the device and settings. The skin must be intact and stable, with careful attention to pigment-change and scarring risk. Start conservatively and use strict sun protection; do not treat over a healing incision or an area with persistent redness or poor circulation.
