Do old scars still respond to laser treatment?

What a scar actually is

When skin heals in a hurry, it prioritizes closure over craftsmanship. The collagen laid down in a scar is denser and less organized than the basket-weave structure of normal skin, which is why a scar catches light differently, sits above or below its surroundings, and keeps doing so indefinitely. Left alone, that tissue is stable; it neither worsens nor meaningfully improves after its first year or so.

Stable is the important word. The scar is not degrading or expiring, but it is also not going anywhere on its own, which is precisely why a fifteen-year-old scar and a three-year-old scar are both still candidates for the same treatment.

Remodeling, not removal

Laser scar treatment works by prompting the scar to rebuild itself better. Targeted laser energy stimulates the tissue to reorganize, gradually replacing dense, disordered collagen with structure closer to normal skin, while surface texture and tone even out alongside. Sessions are comfortable, run 20 to 30 minutes, and carry minimal downtime, with improvement accumulating progressively across a series.

The honest framing matters: the goal is a scar that is visibly softer, flatter, and blended toward the surrounding skin, not an erasure. Anyone promising invisibility is selling. What remodeling reliably delivers is a scar that stops being the first thing light finds on your face.

Acne scars, surgical scars, same principle

Atrophic acne scarring (the indented icepick, boxcar, and rolling types) and surgical scars (typically linear and sometimes raised) are different architectures of the same underlying problem, disorganized repair tissue. The treatment addresses both; the plan simply adapts to the scar's type, depth, and location. Safety across skin tones holds here too, since Aerolase's gentle, selective delivery was designed for every complexion.
