刺青除去用レーザー　 PicoWay®

結晶性台車上ピコ秒

Overview
PicoWay® is an advanced picosecond laser device designed for non-invasive medical and aesthetic treatments. The system delivers ultra-short picosecond pulses (trillionths of a second) and high peak power to produce a photoacoustic effect that fragments pigment and tattoo ink while minimizing thermal damage to surrounding tissue.

Key Benefits

• Low to no downtime: Typical 15–20 minute treatment sessions; epidermis remains intact for faster recovery.
• Photoacoustic mechanism: Ultra-short pulses reduce heating and limit collateral tissue damage.
• Minimized risk for darker skin types: Picosecond pulses reduce risk of hypopigmentation and scarring versus slower nanosecond lasers.
• Patient comfort: Resolve applicators stimulate collagen and elastin with quick, comfortable sessions.
• High clinical improvement rates reported: examples include 94% improvement in acne scars, 92% in wrinkles, 96% in benign pigmented lesions, and 86% in tattoo removal across cited studies.
• High configurability: Adjustable wavelength, beam delivery, energy, spot size and repetition rate for customizable treatments.

Applications
Advance your practice with PicoWay treatments for tattoo removal, benign pigmented lesions, melasma, acne scars, wrinkles and other pigmentation concerns.

Indications by Wavelength and Handpiece

• Zoom 532 nm: Red, yellow, and orange tattoo removal (Fitzpatrick I–III); benign pigmented lesions (I–IV); melasma (I–IV); Café au lait macules (CALMs) (I–IV); lentigines (I–IV).
• Zoom 1064 nm: Black, brown, green, blue, and purple tattoo removal (Fitzpatrick I–VI); benign pigmented lesions (I–IV); melasma (I–IV); Nevus of Ota (III–IV).
• 730 nm: Blue and green tattoo removal (II–IV); benign pigmented lesions (I–IV); lentigines (I–IV).
• 785 nm: Blue and green tattoo removal (II–IV); benign pigmented lesions (I–IV).
• Resolve 532 nm / 532 nm HE: Benign pigmented lesions (I–IV); wrinkles (I–IV).
• Resolve 1064 nm: Benign pigmented lesions (I–IV); wrinkles (I–IV); melasma (I–IV); acne scars (II–V).
• Resolve Fusion 532 nm: Benign pigmented lesions (I–IV).

PicoWay Applicators and Delivery Options
The device offers multiple handpieces and beam delivery technologies to support a wide variety of clinical needs:

• Zoom — full beam delivery; wavelengths: 532 nm and 1064 nm (single applicator); treatment spot sizes: 2–10 mm.
• 730 nm — full beam; treatment spot sizes: 2, 3, 4 mm.
• 785 nm — full beam using Ti:sapphire crystal; spot sizes: 2, 3, 4 mm.
• PicoWay Resolve™ — micro-beam delivery; wavelengths: 532 nm and 1064 nm (two applicators); treatment spot size: 6×6 mm.
• PicoWay Resolve Fusion™ 532 nm — micro-beam with surrounding diffuse ring; wavelength: 532 nm; treatment spot size: 6×6 mm.

How it Works
The PicoWay laser uses ultra-short picosecond pulses to target and shatter pigment or tattoo ink particles via a photoacoustic effect. Fragmented particles are then cleared by the body’s natural processes. For acne scars and wrinkles, PicoWay fractional/Resolve handpieces create controlled microscopic vacuoles (LIOB—laser induced optical breakdown) that stimulate new collagen and elastin formation beneath the epidermis without ablating the surface.

Performance and Features

• Four true picosecond wavelengths and pulses for treatment customization.
• Wide variety of beam delivery technologies: full-beam, micro-beam (Resolve), and micro-beam with fusion ring (Resolve Fusion).
• Large and variable spot sizes for faster coverage and deeper penetration.
• High peak power enabling efficient treatments.
• Enhanced articulated arm option for extended reach, improved stability and beam alignment.
• Linked, easy-to-use user interface; zoom handpieces permit direct dial control visible on the system screen.
• Fast initiation time (ready to use in under 2 minutes) and Pulse-on-Demand for long flash lamp life.

Clinical Outcomes & Usage Notes
Clinical studies and internal data cited on the device report strong improvement rates across acne scars, wrinkles, benign pigmented lesions and tattoos. Typical tattoo removal often requires multiple sessions (commonly reported range: 4–10 sessions spaced 6–8 weeks apart), with variation depending on tattoo size, ink density, colors, and skin type. The 1064 nm Nd:YAG wavelength is highlighted as an option for treating darker skin types due to deeper penetration and reduced epidermal melanin absorption.

System Highlights / What You Can Treat

• Treat the widest range of tattoo colors, including challenging blue and green inks.
• Reduce and eliminate unwanted pigmented lesions: sunspots, age spots, freckles, lentigines, Café au lait Macules, Nevus of Ota.
• Reduce wrinkles and improve acne scars through Resolve fractional treatments.
• Address melasma and other pigmentary disorders with appropriate handpieces and protocols.

Regulatory & Clearance Notes
PicoWay has FDA clearances and other regional regulatory clearances (as cited by the manufacturer) for multiple indications including tattoo removal, benign pigmented lesions, melasma, acne scars and wrinkles.
