Abstract

Objective: To evaluate the results of health education communication on improving knowledge and skin care practice in patients with acne vulgaris. Methods: A pre-post intervention study was conducted at Hanoi Dermatology Hospital (Apr–Oct 2022) on 196 acne patients (mean age 20.5±3.7 years; 51.5% female). At baseline, patients’ knowledge and self-care practices were assessed by questionnaires. The intervention consisted of three weekly educational sessions and distribution of skin care materials. One month later, knowledge and practice were re-assessed. Results: After intervention, the mean knowledge score (out of 15) increased from 7.04±4.96 to 12.29±3.14 (74% increase, p<0.001). The percentage of patients with “good” knowledge increased from 23.0% to 62.8%, while “poor” knowledge dropped from 47.4% to 6.1% (p<0.001). The mean practice score increased from 28.69±5.95 to 34.53±4.54 (p<0.001). All six subcategories of care practice improved significantly, especially hygiene habits (4.86±1.79 to 6.87±0.88, p<0.001). Conclusion: Health education communication significantly improved patients’ knowledge and self-care practices regarding acne. This approach is effective for enhancing patient outcomes in acne management.
