Definition
A laser that heats tissue beneath the skin's surface to stimulate collagen without removing or destroying the outer layer, resulting in little to no visible peeling.
Non-ablative lasers pass through the top layer of skin (the epidermis) to deliver heat into the deeper dermis. The surface stays intact, so there's no open wound, scabbing, or significant peeling — just mild redness and tightness that fades within a couple of days. The trade-off: results build gradually over a series of sessions instead of one dramatic treatment.
Collagen
The most abundant protein in the body, responsible for skin's firmness, elasticity, and structural integrity. Production declines with age.
ResurFX
A non-ablative fractional laser by Lumenis that resurfaces skin by creating microscopic columns of heat deep in the dermis to stimulate new collagen.
Fractional Laser
A laser that delivers energy in a grid of tiny columns rather than treating the entire skin surface at once, allowing faster healing while reaching deep skin layers.
