Laser therapy for skin rejuvenation is called "photo rejuvenation" and is used by many who have sun damage, hyper-pigmentation, large pores or rosacea. (Vanaman, 2010) Photo rejuvenation is not invasive and treats the areas of the skin that need help whilst leaving the tissue around the area untouched, which is one of the many benefits of the process. Treatment works by delivering a pulsating light through a filtered system so that the skin can receive the light energy of the photons in the laser or IPL and become stimulated in order to produce collagen and elastin. (Vanaman, 2010) .This helps the skin in its appearance. Skin tone and texture will both be improved through this process. LLLT or low laser light therapy, also known as "cold therapy" is used in periods from fifteen minutes to forty-five minutes depending on the area of the skin that needs to be covered.. Low level laser therapy is effective due to how cells respond to the laser treatment. Lasers are targeted at an area, for example a place on the face where there is a dermatological issue, and the focused beam of electron current is fired at the targeted areas. When the laser is applied to cells it is called photo-biostimulation. .Cells in the body are able to communicate to one another through the electric stimulation and the photo-biostimulation is able to initiate cell function to allow the beginning of rejuvenation and repairs. (Sunderland, 2011) A laser has the capacity to transmit approximately three inches below the skin although the goal here is to work with the top layers. Therefore a lower level of laser beam is needed. The photons from the beam of the laser hits mitochondria in the skin membranes that absorb the laser light and cause an increase in what is called adenosintriphosphat (ATP) production.(Sunderland, 2011). This chemical helps to rejuvenate cells. The more ATP that is release the healthier the cells become and collagen is also released so that skin rejuvenation can take place. (Horoshovitz, 2007) Photo-biostimulation also allows cell function that enhances collagen level increases and thus enzyme production and cell growth can occur. This also keeps skin from scarring as a result of low level laser treatment for skin rejuvenation. (Horoshovitz, 2007) Treatments for skin rejuvenation can take up to three or four weeks and are applied on the same area until the desired look is created from the treatment. There may be slight swelling at first but this will disappear within a short time and is only a temporary issue. Benefits to LLLT are that it targets only the skin pigment and blood vessels and other areas of the skin are left intact. Results are often seen after one treatment. (Vanaman, 2010). For those who may have some pain from the treatment a topical anaesthetic is available. Some bruising and swelling occur and occasionally some darkening can occur on age spots. On rare occasions there may be blistering or drainage.(Vanaman, 2010). Overall, LLLT is a highly successful way to achieve safe and effective skin rejuvenation. and is being used regularly with fantastic results. References Horoshovitz, J.
