Various types of lasers and light treatments have been shown to be effective in improving pigment issues like sunspots or freckles. The downside, however, is that it usually takes several sessions to see the final results. A new study has found that combining a laser procedure with an optimized pulsed light treatment eliminates more excess pigmentation in just one application than when treated with the laser alone.

During the study, 26 patients received a nonablative, fractional laser treatment. Another 10 participants had the same laser treatment along with the pulsed light. The group that received both reported a 2.4 point improvement on a 1-to-4 scale. The laser-only group came in with 1.2 points, Chestnut Hill, MA, dermatologist Chung-Yin Stanley Chan, MD, reported during the American Society for Laser Medicine and Surgery annual meeting.

Dr. Chan used an Er:Glass laser to conduct the study along with the optimized pulsed light, and alternated which was performed first. Those who received the light first tolerated the total treatment better than those who got laser first. All of the participants also noticed a modest improvement in wrinkles, but those results didn’t vary much between the two groups.

As would be expected during a laser treatment, some of the patients reported flaking, itchy or red skin, or, on a rare occasion, post-inflammatory hyperpigmentation. However, all of the side effects resolved themselves within a month, the researchers found during follow-up examinations.

Some laser treatments can be painful, producing a snapping effect. Most light treatments simply warm the skin when administered. Would you be up for a dual-procedure like this?
