Since lasers were introduced into the cosmetic industry, they have come a long way. Many types of lasers are available today for removing tattoos, removing hair, and resurfacing the skin. A unique feature of the Picoway Resolve laser is its extremely short bursts of energy (measured in picoseconds). Energy bursts target unwanted pigment, such as reddish or pink stretch marks, and break it up into tiny particles, which your body absorbs. The Picoway laser can also stimulate collagen production in your skin, resulting in smoother skin and fewer stretch marks. Laser treatments may not be as effective if your stretch marks do not have a lot of pigment. Increased collagen production, however, could still be beneficial.
