Since their 1958 discovery, lasers have become a powerful industrial tool, but it’s their application in modern medicine which have had truly revolutionary repercussions. Unlike conventional cutting tools, lasers used as surgical tools can cut through tissue without causing excessive bleeding. In fact, lasers actually can coagulate tissue to help stop excessive bleeding – something a knife simply can’t do.
The primary principle behind laser technology is selective photothermolysis (SPTL), the matching of a specific wavelength of light with a pulse duration to obtain optimal effect on a targeted tissue instead of causing damage to surrounding tissue. As such, lasers can cause specific localized damage by selectively heating desired target matter while not heating the rest of the skin. It does this by using the simple fact that light is absorbed by dark objects, so laser energy can be absorbed by dark material in the skin but with much more speed and intensity. To assist in targeting, dark target matter can be naturally occurring or artificially introduced.
The secret behind laser treatment’s ability to restore your beautiful, youthful skin appearance lies in collagen. Collagen is the principal protein of the skin, tendons, cartilage, bone, and connective tissue, which helps give the skin its texture. Natural aging, and factors such as sun damage and smoking, help break down the collagen layer so that the skin’s once smooth surface develops wrinkles. How does the treatment help? New, more youthful collagen actually forms after the procedure.
