Acupuncture for Refractory Rosacea: A Study on Its Effectiveness and Safety

January 28, 2026 updated by: Xiangya Hospital of Central South University

A Randomized, Multicenter, Single-blind, Sham-controlled Clinical Trial on the Efficacy and Safety of Acupuncture in the Treatment of Refractory Rosacea.

This study is a randomized, multicenter, sham-controlled clinical trial designed to evaluate the efficacy and safety of acupuncture for patients with refractory rosacea. A total of 104 participants will be enrolled and randomly assigned in a 1:1 ratio to the acupuncture group or the sham acupuncture group (52 participants in each group, regardless of sex). The primary aim is to determine whether acupuncture can effectively alleviate facial erythema and flushing episodes compared with sham stimulation.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants in the acupuncture group will receive electroacupuncture treatment using continuous waves at a frequency of 1 Hz, delivering microcurrent intensity comparable to human bioelectric levels for 20 minutes per session. Participants in the sham group will receive noninvasive stimulation with blunt-tipped needles that do not penetrate the skin. The study duration is 17 weeks in total, consisting of a 1-week baseline observation period, an 8-week treatment phase (16 treatment sessions in total), and an 8-week follow-up phase. Five in-person assessment visits will be conducted at weeks 0, 4, 8, and 12, followed by an online follow-up at week 16. The study will assess improvements in rosacea symptoms and monitor treatment safety throughout the study period.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: acupuncture group
Device: Acupuncture
The acupuncture sites are primarily located on the face, neck, and proximal limbs along major blood vessels. The specific acupoints include Jiquan (HT1), Yinlian (LR11), Weizhong (BL40), Chize (LU5), and facial Ashi points. The needles are inserted to a depth of 2-3 mm, retained, and stimulated with continuous waves at a frequency of 1 Hz for 20 minutes. Electrical stimulation is not applied to the facial Ashi points, where needles are retained only. The treatment course lasts for 8 weeks, with two sessions per week, for a total of 16 sessions.
Sham Comparator: sham acupuncture group
Procedure: Sham Acupuncture
Use blunt-tipped acupuncture needles to deliver sham stimulation. The blunt needles do not penetrate the skin. The treatment sites, needle retention time, and electrical stimulation frequency are identical to those in the acupuncture group. The treatment duration and frequency are also the same as in the acupuncture group.
