Title : Clinical evidence of innovative water-based sunscreen for acne prone and sensitive skin for indonesia women

Abstract:

Indonesia’s climate is hot and high humidity with temperature ranging between 22.8 - 30.2 deg C and humidity between 61 to 95% in average cities [1] and has a high prevalence of acne vulgaris (AV) skin disease[2]. The extreme climate conditions lead to the overproduction of sweat and sebum that make it uncomfortable to use sunscreen with heavy spreading and thick layers (oil or silicone-based). Excessive sun exposure can lead to acne worsen[3] and may cause sunburn and redness to sensitive skin. Hence, the need for light and watery sunscreen for acne-prone skin and sensitive skin is rising. In this study, we aim to prove the efficacy of two innovative water-based sunscreen formulations that are suitable for acne-prone skin in extreme climates using total acne solution technology. Total acne solution technology is an innovative technology in sunscreen that combines water-based sunscreen formulation with calming acne active for every stage of acne; before acne, during acne, and after acne. We also tested one water-based transparent physical sunscreen for sensitive skin with skin barrier improvement benefit. The clinical efficacies were conducted for 14 and 28 days under dermatology evaluation and instrument analysis for 30 subjects. The subjects of the test are Indonesian women with skin type between III - IV with acne skin (for acne sunscreen) and sensitive skin (for physical sunscreen) condition. The efficacy result of water-based acne sunscreen SPF 35 PA+++ proven to reduce comedones and acnes respectively by -11.84% (p<0.05) and -67.78% (p<0.05) at D28. For water-based acne sunscreen SPF 50 PA++++, the result of comedones and acne improvement starting since D14 by reduction at -18.93% (p<0.05) and -27.37% (p<0.05). The difference of anti-acne actives in sunscreen SPF 50 lead to faster comedo and acne improvement than sunscreen SPF 35. The physical sunscreen SPF 50+ PA++++ also showed improvement in skin barrier by reduction of TEWL -11.30% and -13.82% significantly at D14 and D28 and reduced skin erythema by Mexameter at -3.53% (p<0.05). In conclusion, the proposed water-based sunscreen for acne and sensitive skin were performing good clinical evidence and high satisfactory level.
