18309 The impact of a photoprotection product and the effects of seasonality on photo-aged Chinese women

Abstract

Skin aging is mainly driven by daily environmental exposure especially from UV and pollutants. Research has shown that clinical signs of aging are worsened linearly with age but at a higher rate found in sun-exposed subjects compared with those who regularly avoid sun exposure1. The present study is to evaluate the ability of a daily photo-protection product, with high UVA and UVB protection reinforced with antioxidants, to allow skin better correct itself by protecting it from sun exposure over 6-months. A 6-month, single-center, randomized clinical study was conducted on 118 non–sunscreen using Chinese women aged 35-65 with mild to moderate signs of photodamaged facial skin and have been living in their respective city for at least 10 years. Subjects were randomized into the sun-protected or the control group. The sun-protected group was given the test product to be used once daily in the morning with their normal facial routine. The control group maintained their normal routine. Both cells were balanced with the numbers of sun exposed and sun avoiding subjects. Clinical evaluations were conducted, photographs and questionnaires were captured at baseline, months 3 and 6. Results Results of the clinical grading showed statistically significant improvement in hyperpigmentation, wrinkles, skin tone evenness and dark spot intensity across both cells at months 3 and 6 compared with baseline. The sun-protected group showed statistical significant outperformance over the control group on all the mentioned attributes and time points. The test product was also well regarded by the subjects.
