How long does fractional laser treatment take to work for sun-damaged skin?

The laser creates controlled microscopic treatment zones in the skin. The surface first settles, then the skin repairs those zones and remodels collagen. Redness, swelling, dryness or peeling can make the skin look temporarily different before the underlying improvement is clear. Results depend on the laser settings, the extent of sun damage, skin type and whether more than one session is planned. Fine texture and uneven tone may change at different speeds.

Follow the aftercare plan for cleansing, moisturising and sun protection. Avoid picking peeling skin and pause irritating products until your clinician says they can be restarted. Take photographs in similar lighting if you want to compare progress. Attend review appointments, because your clinician can distinguish normal healing from irritation and decide whether another session is appropriate.

Contact the treating clinic if pain, swelling, warmth, blistering, oozing or redness is worsening rather than settling, or if you develop fever or a spreading rash. Seek prompt medical advice for eye symptoms after treatment near the eyes. A delayed result alone is usually a reason to arrange review, not to increase treatment intensity yourself.

Ask which changes are realistic for your type of sun damage, when your skin should be assessed, how many sessions may be considered, and which products or activities should be avoided during recovery.
