Picosecond Laser Technology at Elyzea
Ultra-short pulses (trillionths of a second) — photoacoustic, not thermal
Picosecond lasers (PicoSure, PicoWay, PicoQ and similar) marked a generational leap over traditional Q-switched systems. Shortening pulse duration from nanoseconds to picoseconds (1000× shorter) changes the primary mechanism: instead of heat fragmenting pigment, it's a pressure wave (photoacoustic effect). The clinical consequences: less thermal damage, less inflammation, safer on darker skin.
Technical data
| Pulse duration | Picoseconds (10⁻¹² s) — typically 300–450 ps |
| Wavelengths | 532 nm (red/yellow/pink), 755 nm (dark ink, melasma), 1064 nm (blue/green/dark tattoos on darker skin) |
| Primary mechanism | Photoacoustic (pressure wave) |
| Certifications | FDA (USA), CE (Europe), DIGEMID (Peru) |
| Indications | Sun spots, melasma, lentigines, PIH, tattoos, micropigmentation, rejuvenation |
| Safe phototypes | I to VI (one of the safest lasers on darker skin) |
| Downtime | 1–3 days mild redness |
Why we chose picosecond
Minimal thermal damage
Pulse 1000× shorter than traditional Q-switched. Ink fragments mechanically, not from excess heat that could burn the skin.
Safe on darker skin
Less heat = less risk of post-inflammatory hyperpigmentation. One of the few lasers where phototype IV-VI doesn't significantly limit use.
Multiple wavelengths
532/755/1064 nm treat different pigments and depths. Single-wavelength clones limit indications.
Fewer sessions
Simple spots: 1–3 sessions (vs 5–8 with Q-switched). Tattoos: 30-50% fewer sessions than traditional lasers.
How it's configured
Dra. Geldres selects wavelength, fluence, and spot size per case:
- ✦ Sun spots: 532 nm or 755 nm, medium fluence, 1–3 sessions
- ✦ Melasma: 1064 nm, low fluence, 4–6 sessions (avoid over-stimulation)
- ✦ Black tattoos: 1064 nm, high fluence, 4–10 sessions per ink
- ✦ Micropigmentation: 755 nm or combination, 3–5 sessions
