Picosecond Laser: Tattoos and Skin Rejuvenation.

Picosecond laser technology was cleared by Food and Drug Administration in 2012 and enhanced our ability to clear both benign pigmentation and dermal ink through a photomechanical impact created in the tissue. This impact created is greater than comparative nanotechnology and can be accomplished with lower fluences and smaller pulse durations. The addition of a diffractive lens array (FOCUS lens) has created a new category in skin rejuvenation by stimulating elastin and collagen through photomechanical and photoacoustic effects and not only through traditional photothermal tissue effects.
