How Does Pico Laser Work? Let’s Deep Dive
Pico Laser works by delivering picosecond pulses at 1 trillionth of a second to shatter pigment and stimulate collagen using photoacoustic effect. Picosecond technology creates pressure waves that break melanin and ink into tiny dust-like particles without excess heat.
How Does Pico Laser Work Step by Step
Pico Laser uses ultra-short pulse duration to target pigment with minimal thermal damage.
Step | Process | Pulse Duration | Biological Effect |
|---|---|---|---|
| Laser emits picosecond pulse | 300-750 picoseconds | Light absorbed by pigment |
| Pressure wave generated | 10^-12 seconds | Shatters pigment into micro particles |
| Macrophages remove fragments | 2-8 weeks | Pigment, tattoo ink clears via lymphatic system |
| LIOB effect in dermis | With fractional lens | Creates micro-injuries to boost collagen |
| New collagen forms | 1-3 months | Improves acne scars, pores, texture |
Picosecond technology is 1000x faster than Q-switched nanosecond lasers. Faster pulse = more photoacoustic impact, less heat.
How Does Pico Laser Work on Pigment and Tattoo
Pico Laser works by selective photothermolysis using specific wavelengths to target pigment.
Wavelengths and targets:
- 532nm: Red, orange pigment. Epidermal pigmentation like freckles, sun spots.
- 755nm: Black, blue, green pigment. Dermal pigmentation like melasma, Hori’s nevus.
- 1064nm: Black, dark blue pigment. Deep dermal pigment, tattoos. Safe for Fitzpatrick IV-VI.
How Pico Laser works on tattoos:
- Ink particles absorb picosecond pulse.
- Pressure wave fractures ink into nano fragments.
- Body’s immune system clears fragments faster than nanosecond laser.
- Requires 30-50% fewer sessions vs Q-switched.
How Does Pico Laser Work for Acne Scars and Rejuvenation
Pico Laser works using Laser Induced Optical Breakdown LIOB with fractional handpiece.
Mode | How It Works | Treats | Downtime |
|---|---|---|---|
Pigment Mode | Full beam shatters melanin | Melasma, PIH, sun spots | 0-1 day redness |
Tattoo Mode | High fluence breaks ink | Professional, amateur tattoos | 1-3 days |
Fractional Mode | Micro-lens creates LIOB | Acne scars, pores, wrinkles | 1-3 days pinkness |
Carbon Peel | Carbon lotion + 1064nm | Oil control, brightening | 0 days |
LIOB creates plasma bubbles in dermis without ablation. This triggers collagen and elastin remodeling for scar revision and skin tightening.
Picosecond Technology vs Q-Switched Nanosecond
Factor | Pico Laser | Q-Switched Laser | How Pico Laser Works Better |
|---|---|---|---|
Pulse Duration | 300-750 picoseconds | 5-20 nanoseconds | 1000x faster = less heat |
Mechanism | Photoacoustic + photothermal | Photothermal only | Breaks pigment by pressure |
Heat Damage | Minimal | Moderate | Lower PIH risk in Asian skin |
Tattoo Clearance | 4-6 sessions avg | 8-15 sessions avg | 40% faster clearance |
Acne Scars | Yes with LIOB | No | Stimulates collagen without heat |
Downtime | 0-3 days | 3-7 days | Faster recovery |
How Pico Laser works makes it safer for Fitzpatrick III-VI skin. Less heat means lower risk of post-inflammatory hyperpigmentation vs nanosecond lasers.
