These problems are melanin or pigment. The 570 is an excellent choice for strictly brown spots on most skin types, except very dark skin. The Dye VL is the treatment of choice when the sun damage includes “reds”. Most sun damage has a background red hue & even surface blood vessels which literally disappear after 1-2 treatments with Dye VL. This handpiece is revolutionary in that it is “in-motion”. A patient’s back/arms/shoulder/chest/neck & face can be treated fast & efficiently in 45 minutes or less. An amazing improvement from the old IPL treatments, with virtually no pain.
