PICO Laser: How It Works
PICO laser technology represents a quantum leap in laser treatments, delivering ultra-short pulses measured in picoseconds (trillionths of a second) for superior results with less downtime.
What Makes PICO Different?
Pulse Duration Comparison:
- Traditional Nanosecond Lasers: 5-50 nanoseconds
- PICO Lasers: 300-750 picoseconds (1000x faster)
How PICO Laser Works
Photomechanical Effect
Unlike traditional lasers that rely on heat (photothermal effect), PICO lasers use ultra-short pulses to create a photomechanical effect:
- Rapid Energy Delivery: Picosecond pulses deliver energy so quickly that target tissue shatters rather than heats
- Particle Fragmentation: Ink particles or pigment break into microscopic fragments
- Natural Removal: Lymphatic system easily removes ultra-fine particles
- Minimal Heat: Reduced thermal damage to surrounding tissue
Clinical Applications
1. Tattoo Removal
PICO lasers excel at tattoo removal:
- Treats all ink colors including stubborn blues and greens
- Fewer sessions required (30-50% reduction)
- Minimal scarring risk
- Less pain and downtime
2. Pigmentation Treatment
Effectively treats:
- Melasma
- Age spots and sun damage
- Post-inflammatory hyperpigmentation
- Freckles
3. Skin Rejuvenation
Stimulates collagen production without surface damage:
- Reduces fine lines and wrinkles
- Improves skin texture
- Minimizes pore size
- Evening of skin tone
Advantages Over Traditional Lasers
| Feature | Traditional Laser | PICO Laser |
|---|---|---|
| Treatment Sessions | 10-15 | 6-8 |
| Downtime | 7-10 days | 1-3 days |
| Pain Level | Moderate-High | Low-Moderate |
| Scarring Risk | Moderate | Very Low |
Treatment Experience
What to expect during PICO laser treatment:
- Duration: 15-30 minutes per session
- Sensation: Rubber band snapping feeling
- Immediate After: Mild redness and swelling
- Recovery: Normal activities within 24 hours
