What is PiQo4?
Laser Treatment: PiQo4
Best For: removing dark pigmentation
Downtime: redness for a few hours
The PiQo4 laser uses energy specifically aimed at a spot of discoloration of concern, and delivers it so fast that the pigment is immediately shattered with minimal heat generated. "That makes them safer for those with melasma and darker skin tones," notes Dr. Herrmann. This non-ablative picosecond laser is specifically designed for removing pigment, which can include everything from sun damage to melasma to post inflammatory discolorations from acne to birthmarks to discolored scars. It's also the go-to for removing tattoos.
The PiQo4 laser is actually pretty revolutionary — instead of using heat like most lasers, this one uses acoustic or sound energy to obliterate discolorations of the skin. According to Dr. Herrmann, the PiQ04 laser is the only laser in the US that has four different wavelengths and the ability to deliver pulses in picoseconds (one trillionth of a second!), meaning it targets just the unwanted pigment and leaves the normal surrounding skin alone. Once dissipated, the pigment naturally gets disposed by your body's lymphatic system.
You'll notice that during the procedure, there is a popping sound that comes with each laser pulse — but not to worry, this is just the photo-acoustic effect. Most people find the pain levels pretty tolerable, and you'll probably feel like you have a sunburn on the affected area after the treatment.
