What They Treat: Moderate sun damage, melasma, minor scars

How They Work: Here were talking surface-sparing fractional lasers, and picosecond lasers outfitted with something called a diffractive lens, which essentially fractionates, or breaks up, the beam. (These tools cover widespread areas, not lone spots, and are appropriate for most skin types.) "Their main role is to refresh and rejuvenate by building new collagen, helping to smooth the skin, and eliminating some of the pigment that comes from sun damage," says Chapas.

Engineered to curtail downtime, fractional lasers hit the skin in a pixelated pattern, with some columns receiving a dose of light, and others going untouched. Picosecond devices deliver varying intensities of energy across the skin, "creating a vibration [rather than heat], which triggers cell signaling and the production of new collagen," Anolik explains.
