This study was a single-center, case-by-case, bilateral facial comparison study. A total of 15 patients were included. On the day of enrollment, after the completion of the test items, treatment was carried out (full face gold micro-needling + 30% salicylic acid on the half face), and on-site follow-up was conducted 1 week later, 2 weeks later follow-up was conducted and the second acid brushing treatment was performed, 4 weeks later follow-up was conducted and the third acid brushing treatment was performed, on-site follow-up was conducted at the 8th week and the 12th week, and the follow-up contents included: Visia photography, camera photography, non-invasive skin testing, questionnaire assessment, etc. The study duration was 12 weeks.
This study is a single-center case-control study with half-side face as the control group. According to the inclusion and exclusion criteria, 15 patients with rosacea (erythema and telangiectasia type) were included. Before and after treatment, various skin indicators of the patients were evaluated and followed up. Through screening, subjects who met all the inclusion criteria and did not violate any of the exclusion criteria would be included in this study. The researchers measured and evaluated the various skin indicators of the patients. On the day of enrollment, the project was completed and treatment was carried out (full face gold micro-needling + 30% salicylic acid on half-side face), and then on-site follow-up was conducted 1 week later, 2 weeks later, 4 weeks later, 8 weeks later, and 12 weeks later. The follow-up contents included: Visia photography, camera photography, non-invasive skin detection, questionnaire assessment, etc. The study duration was 12 weeks.

Follow-up visits were conducted at 1 week, 2 weeks, 4 weeks, 8 weeks, 12 weeks. The follow-up contents included visia photography, camera photography, non-invasive skin examination, questionnaire assessment, etc. The study duration was 12 weeks.
Device: Gold micro needles
On the day of enrollment, the treatment was carried out after the completion of the detection items (gold microneedle + 30% salicylic acid on half of the face). A site follow-up was conducted one week later, and then follow-ups were conducted every two weeks for the second and third acid brushing treatments. Follow-up visits were also conducted every four weeks at the 8th and 12th weeks. The follow-up contents included: Visia photography, camera photography, non-invasive skin examination, questionnaire assessment, etc. The study duration was 12 weeks.

The range, quantity and degree of facial erythema
After cleansing the face with Visia, take a rest for 30 minutes at room temperature of 25 degrees Celsius and then take frontal and lateral images.
Time frame: Before the first treatment, 1 week, 2 weeks, 4 weeks, 8 weeks, 12 weeks
Erythema score
Assessment of lesion morphology score: No visible erythema under natural light = 0 points; Mild erythema can be observed under natural light, presenting as pale red, not obvious at a distance of 50 cm, and can be covered by simple makeup or beard covering = 2 points; Moderate erythema can be observed under natural light, presenting as red, obvious at a distance of 50 cm, and simple makeup or beard covering is not sufficient to cover = 4 points; Severe erythema can be observed under natural light, presenting as bright red, still obvious at a distance of more than 50 cm, and simple makeup or beard covering is insufficient to cover = 6 points. Weighted coefficient for the number/area of lesions: 1-10/5%-10% = 1, 11-20/11%-20% = 2, \>20/20% = 3. Total score of lesion severity = Morphology score × Weighted coefficient. Based on the score, calculate the therapeutic index, therapeutic index = (Total score before treatment - Total score after treatment) / Total score before treatment × 100%
