dc.description.abstract | Background: Postinflammatory hyperpigmentation is not a harmful condition, but
can affects appearance and quality of life. Postinflammatory hyperpigmentation
occurs due to increase melanin production after cutaneous inflammation. Sweet
orange (Citrus sinensis L.) is widely cultivated in North Sumatra. The peels, which
are industrial waste, contain bioactive components such as flavonoid which play a
role in improving pigmentation through antioxidant and tyrosinase inhibition
mechanisms.
Objetive: To determine the effect of 0.1% sweet orange peel extract cream (Citrus
sinensis L.) on axillary hyperpigmentation.
Methods: This pre-experimental clinical trial study was conducted with a pretestposttest
design on 32 subjects with axillary hyperpigmentation. Diagnosis was
made through history taking and clinical evaluation. Melanin index was evaluated
using Mexameter® MX 18 before and after the administration of 0.1% sweet orange
peel extract cream, carried out at weeks 0, 2, 4, 6, and 8. Clinical evaluation was
made using Physician Global Assessment. Side effects were recorded during study,
and level of satisfaction was assessed at the end of study. Friedman test was carried
out to see the difference before and after treatment with a p-value <0.05, is
considered significant.
Results: There was significant decrease in melanin index on axillary
hyperpigmentation (p<0.001) after eight weeks administration of 0,1% sweet
orange peel extract cream. Clinical improvement and no side effects were also
noted. All subjects were satisfied by the application of 0.1% sweet orange peel
extract cream.
Conclusion: The use of 0.1% sweet orange peel extract cream can improve
pigmentation and decrease melanin index in axillary hyperpigmentation with no
side effects and good satisfaction. | en_US |
