TFC006 Development and clinical efficacy of a sunscreen containing Spiraea ulmaria extract

Resumo

In tropical countries, like Brazil, due to high temperatures and humidity, most of the population has oily skin, as well as being more intensely exposed to UV radiation from the sun, because of the geographical location. Therefore, the skin of Brazilian needs a high UV protection, include UV A and UV B protection, for the prevention of sunburn, free radicals, skin cancer and early aging. But, people with oily skin, due to excess sebum production, have difficulties in using products containing high content of oil, such as sunscreens with high SPF. Thus, this study aimed to develop a stable sunscreen with high UV protection and a nice touch, supplemented with extract of Spiraea ulmaria, which mainly consists of gallic acid and tannins and works in three ways to fight excess sebum: it inhibits the activity of the enzyme which amplifies the androgen signal responsible for hyper-seborrhea, contracts dilated pores and limits bacterial proliferation.
