Tattoo Removal and Skin Rejuvenation With Picosecond Lasers

Tattoo Removal and Skin Rejuvenation With Picosecond Lasers

Picosecond lasers are an exciting new addition to the world of tattoo removal and skin rejuvenation. These lasers deliver high energy, short pulse durations that are incredibly effective at treating pigmented lesions and tattoos resistant to traditional Q-switched lasers.

Increasingly, lasers have become an essential tool in treating various conditions that affect the appearance of the skin. From birthmarks to melasma to sun damage, these discolorations often present aesthetic concerns for patients.

Treatment with the picosecond laser is typically a non-invasive procedure that is performed in an outpatient facility. Using this technology, doctors can treat many different kinds of discolorations and even provide cosmetic enhancements in a single session with minimal risks.

The laser uses a neodymium-doped yttrium aluminum garnet crystal, such as 532 or 1064 nm (PicoWay Zoom by Quanta, USA). It is used to remove unwanted tattoos or to minimize the appearance of freckles, rashes and other skin imperfections.

When the laser is paired with a diffractive lens array or a zoom handpiece, it creates a thermal injury that triggers the body’s natural healing process to reduce the appearance of blemishes and restore a healthy glow to the skin. The heat generated during the laser treatment triggers a cascade of responses by the body, including triggering collagen synthesis and promoting skin remodelling.

These results are impressive and make the use of the picosecond laser a popular alternative to the Q-switched laser for treating pigmented lesions. This laser can also be used to reduce the appearance of melasma, and it has been reported that it is effective for the removal of solar lentigines as well.

Picosecond lasers also have the potential to improve precision and reduce thermal damage in certain surgical procedures. In particular, picosecond lasers can ablate endoluminal bowel lesions by reducing the cavitation bubbles and shock waves that are generated during laser-induced breakdown of tissue. This results in more precise ablation, less thermal damage to adjacent tissue, and a more accurate removal of the cancerous tumor.

The use of the picosecond laser for treatment of inflammatory hyperpigmentation is also showing promising results in a small study that was recently published. This study analyzed two cases of PIH treated with the combination of a 755-nm alexandrite picosecond laser and a diffractive lens array or zoom handpiece. A reduction of the size, intensity and color of PIH was observed after each treatment with the laser.
