1. How does a Picosecond laser work?
A picosecond laser delivers extremely short pulses, typically in the picosecond range. The rapid energy delivery creates a strong mechanical/photoacoustic effect that breaks tattoo ink into very small particles.
Because the pulse is extremely short, there is less time for heat to spread into surrounding tissue. This makes picosecond technology particularly attractive for:
• Multicolor tattoos
• Stubborn tattoo pigments
• Dense or professional tattoos
• Small and fine pigment particles
• Clients looking for an advanced tattoo-removal option
However, treatment results still depend on the ink color, tattoo depth, ink composition, skin type, tattoo age, treatment parameters and individual healing response.
2. How does a Q-Switched laser work?
A Q-switched laser uses high-energy pulses in the nanosecond range. It has been widely used for professional tattoo removal and can effectively target tattoo pigments through selective absorption and pigment fragmentation.
Common wavelengths include:
• 1064nm – commonly used for black and dark pigments
• 532nm – commonly used for red, orange and some warm-colored pigments
• 755nm – useful for selected blue/green pigments
• 1320nm – available on some multifunctional systems for additional skin applications
A Q-switched system can therefore be a practical choice for salons, aesthetic clinics and distributors that want a versatile and commercially accessible tattoo-removal platform.
| Feature | Picosecond Laser | Q-Switched Laser |
|---|---|---|
| Typical pulse duration | Picoseconds | Nanoseconds |
| Main effect | Strong photoacoustic effect | Photothermal + photoacoustic effect |
| Pigment fragmentation | Very fine particles | Larger pigment fragments |
| Treatment efficiency | Often faster for resistant pigments | Proven and widely used |
| Black tattoos | Excellent | Excellent |
| Multicolor tattoos | Very good, depending on wavelength | Good, depending on wavelength |
| Difficult pigments | Often advantageous | Can require more sessions |
| Skin impact | Generally less thermal diffusion | More heat may be generated |
| Treatment sessions | May reduce sessions for some tattoos | Often requires more sessions |
| Machine cost | Usually higher | Usually more affordable |
| Clinic positioning | Premium tattoo removal | Professional, cost-effective tattoo removal |
Which is better: Picosecond or Q-Switched?
There isn't one universal winner.
Choose Picosecond technology when:
You want to position the clinic around advanced tattoo removal, particularly for difficult or multicolor tattoos, and the higher equipment investment is acceptable.
Choose Q-Switched technology when:
You want a reliable professional tattoo-removal system with multiple wavelengths, broad pigment applications and a more accessible equipment cost.
For a distributor or clinic, the decision should also consider wavelength configuration, maximum energy, spot sizes, repetition rate, cooling system, handpiece design, service support and local regulations-not pulse duration alone.
For a professional tattoo removal machine
A strong commercial configuration can combine multiple wavelengths so practitioners can select the appropriate wavelength according to the tattoo pigment. For example, a 532/755/1064nm multi-wavelength system can provide broader treatment flexibility than a single-wavelength device.
