Laser treatments for acne can deliver results that last from several months up to a year or more, depending on the type of laser, your skin condition, and how well you care for your skin afterward.[1][5][7]
Many people start seeing changes soon after treatment. For example, with fractional CO2 lasers, you might notice quick improvements in skin texture within two to three weeks, followed by steady progress over the next six months as collagen builds up.[2] Other lasers, like UltraClear, show peak effects around five to six weeks, with skin looking smoother and scars less visible.[5] Active acne often improves in four to six weeks, as the laser reduces inflammation and kills bacteria.[4]
The full benefits come from a series of sessions, usually three to six, spaced four to eight weeks apart.[1][3][6] Mild acne or surface marks may need fewer treatments, while deeper scars require more.[1] Results build over time because the laser stimulates your skin to produce new collagen, which fills in scars and evens out texture.[3]
How long the smooth skin lasts varies. Some treatments, like Aerolase, keep skin clear for months after the full series.[7] CO2 laser effects can hold for a year or longer with good habits.[5][8] Factors that help include daily sunscreen to block UV damage, gentle cleansing, and staying hydrated.[1] Without maintenance sessions every six to twelve months, new acne or aging can bring back some issues.[5][6]
Everyone’s skin responds differently based on type, age, and lifestyle. Darker skin tones might take longer to fade marks, and sun exposure can shorten results.[3] Always talk to a dermatologist to match the right laser to your needs.
