Skin tightening is another popular aesthetic procedure that is often performed as a standalone treatment for wrinkle removal or else to tighten loose skin after a liposuction procedure. Now this time, we want the laser light to go below the skin and heat up the tissue underneath called collagen. This is done by a clever method called fractional resurfacing. Tiny microscopic holes are opened in the top layer of the skin using a carbon dioxide laser. Then the skin is irradiated with light from diode lasers at a wavelength around 1550 nm (which is also useful coincidentally in fiber optic communication!) This light passes relatively benignly through the tiny holes and then gets absorbed nicely in the collagen just underneath. This causes heating and tightening of the collagen, and voila, the collagen pulls the skin tighter and smoother.
That’s how it works folks. But don’t think we’re pushing you to go out and get one of these procedures. We think you look great just as you are.
