Expert advocates single pass CO2 laser resurfacing

NEWPORT BEACH, CALIF. – Facial CO₂ laser resurfacing deserves a comeback, according to Victor Ross, MD, director of laser and cosmetic dermatology at the Scripps Clinic in San Diego.

The practice fell out of favor in the late 1990s because of long recovery times, hypopigmentation, and the risk of keloid scars, among other issues. Physicians were just being too aggressive, doing multiple full-field passes in one session, he said at the Summit in Aesthetic Medicine, held by Global Academy for Medical Education.

It turns out that doing one pass very conservatively – with maybe a second pass around the mouth for deeper wrinkles – delivers a lot of the benefits with none of the downsides. It takes maybe 45 minutes, and “we get very nice results, I think better than fractional [laser] results,” Dr. Ross said. The wrinkle-smoothing effect may not be as potent or durable as the old-school approach, “but it’s a more natural look and [there’s] much faster recovery. Patients go pink instead of red,” and can wear makeup sooner. “You don’t get delayed hypopigmentation.”

The general trend in cosmetic dermatology is to do multiple procedures in one office visit instead of spacing them out over several appointments. For instance, lentigines on the hand could be targeted with intense pulsed light and then hand crepiness could be treated with a fractional laser. You “can get a lot done and a very nice result in one” session, but it makes sense to dial settings back maybe 15%-20% when different devices are used on the same area, he said.

I keep several lasers in one room” and sometimes “go back and forth, back and forth like a mad chef,” he said.

Companies are helping further the approach. One company, for instance, has added a nonablative fractional laser to its intense pulsed light platform. Others are combining ablative and nonablative fractional lasers. It’s all about “allowing you to have more flexibility in how you deliver energy,” Dr. Ross said.

Meanwhile, another newer kid on the block, the picosecond laser, has helped a bit with tattoo removal, but “we are still not really hitting a home run. There’s no doubt that picosecond lasers are more efficient than nanosecond lasers, but they’re maybe 20%-30% better,” he said. The problem is that most commercially available picosecond lasers have pulse durations on the order of 500-800 picoseconds, which is not optimal for the smallest pigment particles. If pulse durations are too short and energies too high, “you get this kind of white plasma in the skin, which doesn’t” help.

Industry hasn’t solved the problem yet; for now “I would give us a C-plus on tattoos,” he said.

Dr. Ross had some advice for dermatologists looking to outfit a new cosmetic practice. Right off the bat, “you will need something for red and brown spots, because you are going to see a lot of that.” An intense pulsed light device or a large-spot potassium titanyl phosphate (KTP) laser fills the bill, he said.

He added that he would have a device for resurfacing, and as the third device, “I would get maybe a Q-switch laser for tattoos,” he said.

So armed, a dermatologist could handle much of what’s likely to come through the door.
