how does laser tattoo removal work?

The traditional laser removal method has long been “Q Switched” lasers with nanosecond pulse durations— that’s  bursts of light in one billionth of a second increments. After years of research and advancement in laser technology, the PicoSure Pro was developed and released in 2022. This machine produces picosecond pulse durations — one trillionth of a second — that has the capability of removing tattoos faster, more efficiently, and in a fewer treatments than the traditional Q Switched.

 

While the Q Switched lasers use heat to remove ink (and cause more damage to the skin in the process), the FDA approved PicoSure Pro uses these exceptionally short laser pulses to target the ink particles beneath the skin with a massive amount of pressure. This intense pressure causes the pigments to break apart and fragment into tiny particles which are then absorbed and disposed of by the body’s lymphatic system.

 

Before the recent advancements in technology, picosecond lasers were not as effective at removing stubborn pigments like yellow, orange and red ink when compared to the traditional laser methods. However, scientists were recently successful in improving the picosecond laser method wavelength to remove all ink colours in every skin tone.

 

This new advancement, implementing a 523nm (nanometer) wavelength,  is perfect for targeting those tough pigments. When incorporated with the standard 755nm laser in the PicoSure Pro, this combined system delivers a peerless ability to eliminate unwanted ink across the colour spectrum, regardless of skin tone.

PICOSURE PRO

The World’s 1st 755nm Picosecond Laser

The PicoSure Pro device delivers 755nm energy in picoseconds; the delivery is so quick that it spares the skin from high thermal damage while optimally targeting unwanted pigment, wrinkles, acne scars and pores with less downtime than traditional lasers.

​

​The PicoSure Pro laser makes tattoo removal even easier. The 755nm wavelength is able to target black, blue, and green tattoo inks, while the 532nm wavelength offers effective treatment of “sunset colors”—red, yellow and orange—which are typically hard to correct

​

Reth.ink is one of the first & only laser clinics to offer Picosure PRO in Canada. 

​

Picosure Pro was released in 2022 and can:

  • Remove unwanted pigment safely and effectively in all skin types; the only picosecond device FDA-cleared to treat melasma pigment, nevus of Ota and Hori’s nevus

  • Reduce wrinkles, fine lines, acne scars and pore size with no downtime

  • Improve overall skin tone & texture; providing patients with lighter, brighter and more radiant complexion

  • Remove ALL colours of tattoo ink in ALL skin tones 

​

With over 1 million treatments performed and 100% patient satisfaction*, this has become a popular and trusted treatment worldwide.
