Effect of interstitial low level laser stimulation in skin density
2016
As the interest in skin was increased, number of studies on skin care also have been increased. The reduction of skin
density is one of the symptoms of skin aging. It reduces elasticity of skin and becomes the reason of wrinkle formation.
Low level laser therapy (LLLT) has been suggested as one of the effective therapeutic methods for skin aging as in
hasten to change skin density. This study presents the effect of a minimally invasive laser needle system (MILNS)
(wavelength: 660nm, power: 20mW) in skin density. Rabbits were divided into three groups. Group 1 didn't receive any
laser stimulation as a control group. Group 2 and 3 as test groups were exposed to MILNS with energy of 8J and 6J on
rabbits' dorsal side once a week, respectively. Skin density of rabbits was measured every 12 hours by using an
ultrasound skin scanner.
