How long do laser resurfacing results last?

The common mistake is to treat laser results as a single outcome that lands on one day and stays forever. The timeline is slower and less certain than that.

The timeline my.clevelandclinic.org gives

The page at my.clevelandclinic.org says skin may continue to improve for up to a year and the improvement may last for several years. Both halves use the word "may." That is a range of possibilities, not a promise.

Why a range needs a caution attached

The source does not say how your own skin will respond, and no article can. The Aesthetic Society's page on laser skin resurfacing and the guide on how dermatologists treat sun-damaged skin are good places to compare descriptions. Hold any provider's promised timeline up against them.

Judging your own healing

Judging whether your skin is improving or healing poorly takes a trained eye. Take your questions to the licensed clinician who treated you, and do not rely on photos, forums or a stranger's before-and-after set.

Ask where "several years" comes from

"Several years" is not a guarantee, and anyone who gives you an exact number without examining you is guessing. Ask what they base it on.
