Lasers are widely used for different application in medicine and one predominant usage is Cosmetic surgery. This is due to reproducible property and effective management of cutaneous related disorders. Lasers are used in cosmetics by involving microsurgery technique to treat specific area present in tissue and this process is called photo thermolysis. It involves light absorption by destroying specific cells that are targeted and transfer energy. There is wide range of applications of used lasers cosmetic and it includes-
Treatment of wrinkles and lines thus enhances resurfacing and tightening of skin, improvement of scar, removal of hair and tattoo and resurfacing the skin. Laser application in removal of hair is very popular mainly due to efficacy and speed. However the efficacy is determined based on experience and skills of operating individual and technology used. Carbon dioxide laser is generally used for wart and tag removal.
Cosmetic laser therapy enables the production of collagen and it helps in control and growth of skin injury and also for skin tightening process. Lesions that are associated with pigment for example age and sun spots are treated by using fractional and pulsed dye laser treatment. Ablative and Erbium lasers were used for removal of growth of precancerous cells for example Actinic Keratoses were removed. Laser application in cosmetics uses light source and currently there are different modalities which include LED, radiofrequency and Infrared based technologies. Cosmetic based lasers are of different varieties and are determined based on delivery mode and wavelength. Cosmetic lasers can be modified by combining with metals, gases and stones.
Used lasers cosmetic are meant for treating skin for healing process and it involves penetration of ablative laser into deep layer of skin and treatment procedure is specific and it is based on type and condition of skin. Carbon dioxide laser beam is considered as effective device for cosmetic related surgery and it is mainly used for incision and its effect of homeostasis is unique in comparison with other methods. Cosmetic laser treatment is productive but it has some risks with regard to treatment procedures and also risks for patients involved in therapy. Some examples include prolonged skin redness, skin burns and injury due to excess heat from laser, pain or discomfort, prone to microbial infections, pigmentation changes and scarring. There are different types of cosmetic lasers and determination of laser type for a patient is based on type and condition of skin.
