The ultra-short laser pulses surpass the outer layer of the skin to break up pigment beneath the surface or stimulate collagen and elastin in the dermis depending on the treatment plan. PicoWay® uses different handpieces and laser wavelengths to address sun damage, freckles, acne scars, wrinkles, and skin texture. The Zoom handpiece is designed to target dark spots and pigment (it is also used for tattoo removal). The Resolve handpiece treats acne scars, wrinkles and boosts collagen production.
