Efficacy and Safety of a 1726-nm Sebaceous-Targeting Diode Laser for the Treatment of Fordyce Spots of the Lips: A Prospective Pilot Study

This is a prospective, single-arm pilot study evaluating the use of a 1726-nm diode laser that selectively targets sebaceous glands via lipid absorption. The device employs a temperature-guided, multi-pulse delivery system with continuous cooling and is FDA-cleared for the treatment of inflammatory acne.

Eligible participants with clinically evident Fordyce spots of the lips and/or vermilion border will receive 2-3 treatment sessions spaced four weeks apart. Outcomes include lesion count reduction, global aesthetic improvement scores, patient satisfaction, and safety assessments. Follow-up visits will occur at Weeks 4, 8, 12, 24. To better characterize durability and recurrence, participants will be invited (optional) to return for an additional observational follow-up at Month 12 (±4 weeks), without any additional study treatment. Participants who do not attend the Month-12 visit will be considered complete after the Week-24 assessment and will not be contacted further beyond routine clinical care. All analyses of efficacy and safety will be based on assessments through Week 24, with Month-12 data summarized descriptively as extended follow-up where available.
