Skin Knowledge

Background: Skin care for maintaining skin integrity includes cleansing, skin product use, and photoprotection. Inappropriate skin care can lead to skin problems.

Aims: To evaluate the knowledge, attitude, and practices in skin care among Thai adolescents.

Patients/methods: Questionnaire-based, descriptive, cross-sectional study.

Results: A total of 588 Thai adolescent students (mean age: 15.6 ± 1.8 years, 50.5% female) were included. Of those who responded, 99.5% knew the benefits of cleansing, and 95.9% knew the benefits of skin care products. Skin products, moisturizer, and sunscreen were used by 87.8%, 80.8%, and 71.5% of students, respectively. Female teenagers used moisturizers, cosmetics, and sunscreen significantly more than males (p = 0.001, p = 0.001, and p < 0.001, respectively). High school teenagers applied cosmetics more than junior high school teenagers (p = 0.004). Ninety-three percent of adolescents knew the effects of sunlight, but only 27.4% regularly applied sunscreenThe sources of knowledge were from person, online social media, print media, and television/radio in 88.5%, 77.5%, 30.7%, and 26.1%, respectively. Data from physicians and parents were trusted by 65.3% and 64.2%, respectively. Most (74.1%) adolescents searched for data from more than 1 source. Adolescent females and high school adolescents demonstrated significantly more accurate knowledge and practice in cleansing and photoprotection (p < 0.001) compared with adolescent males and junior high school adolescents. Knowledge and practices did not significantly correlate with underlying skin diseases or monthly allowance.

Conclusion: Gender and education level were found to significantly influence knowledge and practice in skin care among adolescents in Thailand.
