LASER is a special type of light whose wavelength and amplitude is controlled to deliver therapeutic benefits. Scientists and engineers process the energy of light to be able to penetrate various depths of skin and deliver heat. This heat, produced during LASER treatment, is absorbed by target tissue and imparts the therapeutic benefits often called as Photofacial.
There are two types of LASERS used in facial rejuvenation. Ablative and non ablative. Ablative lasers are CO2 and Erbium YAG. These vaporise tissue. Vaporising tissue initiates a healing process which lays down younger and healthy tissue, newer collagen and more elastic fibres. Non ablative lasers are of different wavelengths, which only deliver heat which is absorbed selectively by. The tissue gets destroyed and cleared by our white cells. In the process, new younger and rejuvenated tissue is laid down. This works best to replace the old inelastic collagen ( protein fibre) to new elastic collagen, which improves the elasticity of skin. Pigmentation is cleared by non ablative lasers in a similar way. A combination of ablative and non ablative lasers helps in rejuvenating the skin.
