Detailed Description
Rosacea is a chronic inflammatory disorder which affects the cheek, nose, chin, forehead and eyes. It is typically characterized by cutaneous signs such as flushing, erythema, telangiectasia, papules, and pustules in the face. The pathogenic mechanism of rosacea is unknown, and there is no cure for rosacea. The therapeutic approaches include oral medicine, topical medicine and surgical interventions depending on the different subtypes of rosacea. The recent study demonstrates that combination therapy may be more effectively improved the symptoms of rosacea. Dian dao san is a topical herbal compound for reducing the features as flushing, erythema, papules, and pustules for years. The investigators hypothesize that dian dao san can be more beneficial in treating the patients with rosacea and improving the quality of life.

Outcome Measures
Primary Outcome Measures
- reduction of flushing, erythema, telangiectasia, papules, and pustules [6 weeks]
quantified by Investigator Global Assessment, IGA. IGA is used in the study for assessing the severity of rosacea ranging from 0 (clean) to 4 (most severe).
- absence of adverse skin reaction to topical medicine [6 weeks]
scored with Dyshidrotic Eczema Area and Severity Index (DASI index). The total score of the DASI results from the sum of severity grade score points of each of the four items (V = vesicles, E = erythema, S = desquamation, I = itch) multiplied by the affected area (A) score points: DASI = (pV + pE + pS + pI) × pA. The maximum possible score is 60. By the DASI, the dyshidrotic eczema is graded as: mild (0-15), moderate (16-30) and severe (31-60).
Secondary Outcome Measures
- improvement of life quality [6 weeks]
Dermatology Quality of Life Index, DQoL is the questionnaire which designed to measure the health-related quality of life of adult patients suffering from a skin disease ranging from 0(no effect at all on patient's life) to 30(extremely large effect on patient's life).
