Different structures within our skin respond in a peculiar manner to different wavelengths of cosmetic laser. For instance, hair will respond to laser wavelengths differently than our blood vessels, or certain pigments would respond. As one grows in age, exposure to persistent of ultraviolet (UV) radiation from direct sunlight, impurities in the environment, toxins in our unhealthy diet and other unhealthy lifestyles like smoking all contribute to the reduction or destruction of collagen in the skin. As collagen is gradually lost, the skin tends to lose its natural texture and elasticity. It gets a wrinkled and sagging look.
Skin aging is invariably linked to loss of collagen. Skin surface changes like loose skin or dry, pigmented skin can be treated with cosmetic laser skin rejuvenation techniques. They act effectively on the damaged surface skin cells; remove pigment as well as dead thickened skin, to stimulate new and healthy-looking skin cells to resurface.
As the structures within human skin happen to absorb the laser energy, they get heated up and are gradually destroyed. Since different structures, as mentioned above, respond to a varying degree, medical experts can heat and thus destroy certain structures within the patient’s skin selectively without having any effect on the other healthy or least damaged skin structures.
