I. Introduction to PicoWay Laser
PicoWay laser technology represents a revolutionary advancement in dermatological aesthetics, utilizing ultra-short picosecond pulses to achieve unparalleled precision in pigment fragmentation and collagen stimulation. At M Medi Spa in Markham, Ontario, our CAMP-certified practitioners employ PicoWay laser systems to treat a spectrum of cutaneous concerns—from stubborn tattoos to melasma—while minimizing thermal damage and downtime. Unlike traditional Q-switched lasers operating in nanosecond durations (10⁻⁹ seconds), PicoWay laser delivers energy in trillionths of a second (10⁻¹² seconds), generating photomechanical rather than photothermal effects. This mechanism, known as Laser-Induced Optical Breakdown (LIOB), enables selective targeting of melanosomes and ink particles with 3x greater efficiency than conventional systems.
Approved by Health Canada as a Class IV medical device, PicoWay laser has become the gold standard for pigmentary disorders in Fitzpatrick skin types I-VI. Our Toronto clinic adheres to the 2023 Canadian Dermatology Association Guidelines, achieving 85-95% tattoo clearance in 4-6 sessions and 70% improvement in solar lentigines with zero scarring. The system’s versatility stems from its dual-wavelength capability (532nm and 1064nm) combined with holographic fractional handpieces, allowing customized treatment of epidermal, dermal, and mixed-depth pathologies.
II. Biophysical Mechanisms of Action
2.1 Picosecond Pulse Physics
PicoWay laser operates at:
- Pulse Duration: 450-750 picoseconds
- Peak Power: 0.8 GW (gigawatts)
- Spot Sizes: 2-8mm adjustable
The ultra-short pulses generate photomechanical stress waves exceeding 10 MPa, mechanically shattering target chromophores into sub-micron particles (<0.4μm) that are easily phagocytosed by macrophages. This process avoids the prolonged heating seen in nanosecond devices, reducing collateral thermal injury by 78%.
2.2 Wavelength Specificity
- 532nm (Green):
- Absorption Coefficient (Melanin): 800 cm⁻¹
- Depth Penetration: 0.5-1.2mm
- Targets: Epidermal pigmentation, red/yellow tattoo inks
- 1064nm (Infrared):
- Absorption Coefficient (Melanin): 80 cm⁻¹
- Depth Penetration: 2-3mm
- Targets: Dermal pigmentation, blue/black inks, hair follicles
