Sebacia announces positive results for gold microparticle, laser treatment of acne

Sebacia has announced positive results from two European clinical studies investigating the use of the company’s microparticles in combination with lasers for the treatment of acne.

The microparticles are made of gold and silica and are specially designed to be activated by the light from hair-removal lasers when placed in a suspension designed to penetrate sebaceous follicles, according to a press release. The microparticles then create a focused photothermal effect in the sebaceous gland and follicle to reduce the activity of the gland and inflammatory lesions that cause acne.

Ninety-seven people with acne were included in the randomized studies. In the first study, the control cohort used over-the-counter face wash, whereas in the second study, controls used a suspension without microparticles and laser treatment.

In both studies, there was significant reduction in inflammatory lesion and Investigator’s Global Assessment scores in the patients treated with the microparticles compared with the control cohorts. There was an approximately 60% reduction in lesions at 6 months after baseline.

Side effects included mild erythema and mild edema, according to the release.

“As a simple, two-step, in-office treatment, Sebacia treatment could provide an essential alternative to the daily use of topical and systemic drugs that are currently available for acne,” researcher Witold Owczarek, MD, said in the press release.

Study data were presented at the Five-Continent Congress in December in Hong Kong, according to the release.
