Fibroblasts are skin cells which produce collagen and elastin fibers, necessary for the skin’s support and elasticity. In time, fibroblasts tend to degenerate and as a result skin aging, wrinkles and slackness occur. Also the skin gathers years and hours of sun exposure and photo-aging occurs even in young people. A distinctive example is that of a farmer, whose hands, face and neck were always exposed to sun, their skin is totally aged. While the skin in the rest of her body is more youthful.
Laser treatment aims at fibroblasts in order to activate them by producing collagen and gradually decrease the wrinkles. Other lasers use the method of fractional photo-thermolysis, that is they create controlled invisible micro-injuries so as to activate the mechanisms of physical skin rejuvenation. Skin tightening that is achieved through the use of lasers can be combined with other non-invasive methods such as injectable implants, offering alternative solutions against lifiting and plastic surgery.
