Clinical erythema Score (CEA)

Clinical erythema score (CEA) was divided into no, mild, moderate and severe according to the severity of rosacea, corresponding to 0,1,2,3, respectively.

Time frame: Patients were followed up on the day of treatment and at 1, 2, 3, 4, 6, and 8 weeks after treatment.

Global Aesthetic Improvement Scale Score (GAIS)

The Global Aesthetic Improvement Scale (GAIS) score was evaluated by the treating physician and divided into four levels: very improved corresponding, substantial improvement, improvement, no change; Corresponding to the best beauty effect, significant improvement but not the best, significant improvement, no change;

Time frame: Patients were followed up on the day of treatment and at 1, 2, 3, 4, 6, and 8 weeks after treatment.

Melasma Area and Severity Rating (MASI)

The melasma Area and Severity Rating (MASI) is used to evaluate the severity of melasma. Melanin deposition was quantitatively evaluated from three aspects: area, color depth and color uniformity. Area weight: Forehead 30%, left cheek 30%, right cheek 30%, mandibular 10%, color plaque proportion (A) \< 10% recorded 1 points, 10% \~ 29% recorded 2 points, 30% \~ 49% recorded 3 points, 50% \~ 69% recorded 4 points, 70% \~ 89% recorded 5 points, 90% \~ 100% recorded 6 points; Color depth (D), color uniformity (H) scores range from 0 to 4 points, no score 0 points, slight score 1 points, moderate score 2 points, obvious score 3 points, maximum score 4 points. MASI score = forehead \[0.3A (D+H)\]+ right cheek \[0.3A (D+H)\]+ left cheek \[0.3A (D+H)\]+ mandibular \[0.1A (D+H)\], score range 0 \~ 48, score was positively correlated with melanin deposition.

Time frame: Patients were followed up on the day of treatment and at 1, 2, 3, 4, 6, and 8 weeks after treatment.
