ABSTRACT
Gold microparticles are indicated as an accessory to 1064 nm lasers to facilitate photo-thermal heating of sebaceous glands for treating mild-to-moderate inflammatory acne vulgaris (Sebacia Microparticles, Coronado Aesthetics LLC, Southlake, TX). The following study assessed the safety and clinical benefit of gold microparticles/laser therapy when used together with commercially available topical acne products. Healthy patients, 12 to 45 years old with mild-to-moderate inflammatory facial acne were prescribed a topical pre-treatment retinoid for 3 to 4 weeks. The gold microparticle suspension was then applied to the entire face and massaged into the skin. The laser procedure was performed with commercially available 1064 nm NdYAG lasers with fluence in the 20 to 35 J/cm2 range, a 30 ms pulse duration, and direct cooling. Among participants completing the study (N=52), the mean percent change in inflammatory lesion counts (ILC) was -55% at month 2, reaching -68% at month 12. At that time, 86% of participants achieved a 40% decrease in ILC and 75% achieved a 60% decrease in ILC. Mean Investigator's Global Assessment (IGA) Scale scores decreased by 41.6% from 2.4 at day 0 to 1.4 at month 12. The percentage of participants with clear or almost clear skin increased from 7% at day 0 to 59% at month 12. Acne therapy with topically applied gold microparticles followed by 1064 nm laser irradiation is an effective treatment for moderate to moderately severe acne. The treatment was well-tolerated with a high degree of participant satisfaction. J Drugs Dermatol. 2023;22(11)1088-1094 doi10.36849/JDD.7744.
