PHOENIX – Ever since PicoSure became the first picosecond laser cleared by the Food and Drug Administration for the treatment of unwanted tattoos and pigmented lesions in 2012, new uses for this technology continue to expand.
Now, These include PicoWay, PicoSure, Enlighten, PicoPlus, PiQo4, and Quanta Pico, among others.
“PicoWay technology has integrated nicely into my practice in Houston, the most ethnically diverse city in the country, with its ability to safely treat a number of various benign, congenital, and acquired epidermal and dermal pigmented lesions with ultrashort pulse duration and low thermal impact, which greatly reduces the risk of postinflammatory hyperpigmentation even in darker skin types,” Paul M. Friedman, MD, director of the Dermatology and Laser Surgery Center, Houston, said at the annual conference of the American Society for Laser Medicine and Surgery.
He emphasized the importance of therapeutic clinical endpoints, noting that with q-switched lasers, “you’re looking for immediate whitening, whereas with picosecond lasers, your endpoint is slight whitening or slight darkening depending on wavelength, indication, and skin type. The ability to fractionate picosecond pulses has also allowed us to utilize this technology for photoaging as well as acne scarring.”
The PicoWay system includes a 730-nm picosecond titanium sapphire handpiece, which is FDA cleared for treatment of benign pigmented lesions and blue and green tattoo removal. Dr. Friedman said that he has seen good clinical results using the handpiece for café-au-lait macules, particularly in skin of color.
In an abstract presented at the ASLMS meeting, he and his colleagues presented a retrospective review of 12 patients with café-au-lait macules with Fitzpatrick skin types III-VI who were treated with the PicoWay 730 nm handpiece between April 2021 and January 2023. Patients received a mean of 3.1 treatments at intervals that ranged from 5 to 40 weeks. Clinical photographs were graded by three board-certified dermatologists using a 5-point visual analogue scale.
Overall, patients were rated to have a mean improvement of 26%-50%. Two patients achieved 100% clearance after four to five treatment sessions. “Café-au-lait macules with smooth borders responded less well to laser treatment, confirming prior studies at our center,” he said. “We often educate parents that café-au-lait macules may recur over time, especially with repeated sun exposure.”
Treating melasma
Dr. Friedman’s go-to devices for melasma include the low-density, low-energy 1,927-nm fractional diode laser; the 1,064 nm picosecond Nd:YAG, the low-fluence 1,064 nm Q-switched Nd:YAG with a nanosecond pulse duration, and the 595-nm pulsed dye laser for lesions exhibiting underlying vascularity. He said that combining therapies that target pigment and vasculature may be ideal to prevent relapses. “Melasma is a multifactorial condition so by improving patient education and expectation alongside advances in laser treatment of melasma, we have ultimately improved our ability to treat this condition,” he said.
“We’re approaching it from all angles, with ultraviolet photography and spectrocolorimetry, behavioral modifications, topical skin-lightening agents, broad spectrum sunscreens with protection against visible light, and oral tranexamic acid in advanced cases. Then, we intervene with these energy-based modalities, and the bottom line is, less energy and density is more, with lengthened treatment intervals. In 2023, we’re better than we’ve ever been in terms of our ability to safely and effectively improve melasma.”
Novel lasers
Dr. Friedman also described the UltraClear, a novel ablative fractional 2,910-nm erbium-doped glass fiber laser that delivers a customized blend of ablation and coagulation based on the patient’s condition, skin type, and tolerability for down time. He provided an overview of the versatility of what he described as highly customizable technology for conditions such as photoaging and dyschromia in patients of various skin types, making it a very versatile platform in his practice.
The AVAVA MIRIA system is a “next generation” laser “where you’re able to use a focal point. Basically, you’re treating the skin from the inside out in a 3D manner and you’re able to focus intradermally up to 1 mm with high energy 1,064 nm or 1,550 nm,” he said. “It’s a unique conical geometry that spares the epidermis, combined with sapphire tip cooling and images the skin at the same time with the potential for personalized treatments of dyschromia and photoaging in all skin types. It’s truly remarkable where the technology is heading.”
Dr. Friedman disclosed that he has received consulting fees from Allergan, Galderma, Acclaro, Merz Aesthetics, Solta Medical, and Cytrellis. He has conducted contracted research for Sofwave and is a member of the speakers bureau for Solta Medical and Candela.
