PicoWay Picosecond Laser
246-250ps photoacoustic effect for precise pigment & tattoo removal
이 치료에 대해
PicoWay by Candela is a next-generation picosecond laser system with industry-leading 246-250ps pulse width. The powerful photoacoustic effect shatters melanin and tattoo ink into fine particles. Three wavelengths (1064nm, 532nm, 730nm titanium sapphire) address pigmentation, melasma, tattoo removal, and skin rejuvenation. Fractional mode promotes dermal collagen remodeling. FDA-cleared device.
작용 기전
The 246-250ps ultra-short pulse generates a photoacoustic effect on target pigments, unlike nanosecond thermal effects. Powerful shockwaves fragment melanin and ink particles with minimal thermal damage. Macrophages naturally clear the fragmented particles. The 730nm titanium sapphire wavelength is particularly effective for blue/green tattoo inks. The fractional handpiece promotes LIOB-mediated dermal collagen remodeling.
