| dc.description.abstract | Introduction. Melasma is a common hyperpigmentation disorder among women,
particularly those with darker skin tones or Fitzpatrick skin types IV-VI. Genetic
factors, hormonal influences, and UV exposure are the primary causes of melasma.
UV radiation can cause skin damage, increase melanin production, and exacerbate
melasma. In Indonesia, the majority of the population has Fitzpatrick skin types IIIIV,
which are prone to darkening from sun exposure, leading to a higher incidence of
melasma. Therefore, the use of sunscreen is essential as an effective preventive
measure to reduce the occurrence of melasma. Objective. To determine the
relationship between sunscreen use and sun exposure on the incidence of melasma
among women in Denai Sub-district, Medan Denai District, Medan City. Method.
This study employs an analytical observational design with a cross-sectional
approach. Data were collected through questionnaires and analyzed using Kendall's
tau-b statistical test. Results and Discussion. Among the 62 respondents, the largest
age group was 46 – 50 years (43.5%), which also had the highest incidence of
melasma with 21 respondents. The majority of respondents used sunscreen in the
moderate category (37.1%). In terms of sun exposure, most respondents fell into the
high exposure category, with 32 respondents (51.6%). The relationship between
sunscreen use and melasma incidence showed a p-value of 0.001. Similarly, the
relationship between sun exposure and melasma incidence also showed a p-value of
0.001. Conclusion. There is a significant correlation between sunscreen use and the
incidence of melasma, characterized by a strong. Similarly, there is a significant
correlation between sun exposure and the incidence of melasma, characterized by a
very strong. | en_US |
