How long does laser skin resurfacing last?
Most laser skin resurfacing results last about 3–5 years with good sun protection, and deep ablative CO2 treatments can hold up for 10 or more years. Lighter non-ablative sessions fade sooner and are usually maintained with an annual touch-up. The type of laser, your skin, and your sun habits decide where you land in that range.

Why the Range Is So Wide
Laser resurfacing works by removing or heating the outer layers of skin so your body rebuilds them with fresh collagen — the protein that keeps skin firm and smooth. How long that improvement lasts depends mostly on which category of laser was used. Ablative lasers (CO2 and erbium) remove the surface layer entirely; they come with two to three weeks of real downtime, but a single deep treatment can keep skin noticeably smoother for a decade or more. Non-ablative lasers heat the deeper layers without breaking the surface, so recovery is minimal — the trade-off is gentler results, usually delivered as a series of 3–5 sessions spaced about a month apart, and refreshed yearly.
The second factor is you. The laser resets your skin, but it doesn’t stop it from aging — new sun damage and the natural slowdown in collagen production continue from the day you heal. People who wear broad-spectrum sunscreen daily and skip tanning routinely sit at the long end of the 3–5 year window; sun-seekers can erase their results in a season or two.
One honest caveat: resurfacing improves texture, tone, fine lines, and sun damage — it doesn’t lift sagging skin, and results on deep-set creases are partial. If firmness is your real goal, a skin-tightening treatment like Morpheus8 or a combination plan may serve you better than chasing repeat laser sessions.
