What does a patient experience during and immediately after the procedure?

[Carr]

The sensation of a laser is mild pinching or pricking. Healing is
almost immediate. Irregardless of how impressively this laser changes
tissue, it’s actually a low-level energy version, and is even safe for
use on infants. Side effects are rare, but when they do occur, it will
be bruising, blistering, swelling, or reddening, which goes away in a
few days.
