This is a functional sunscreen focusing on full-scenario light protection, achieving triple effects of UV protection, blue light blocking and antioxidant repair. For sun protection, it adopts SPF 50+ and PA++++ broad-spectrum formula, blocking more than 98% of UVA/UVB rays to meet outdoor sun protection needs. For blue light protection, it is added with highly active red algae extract, lutein and ergothioneine, which can effectively block high-energy visible light (HEV) emitted by electronic screens, neutralize free radicals induced by blue light, reduce skin dullness, yellowing, fine lines and photoaging caused by screen light, and improve the "screen skin" condition of people who face computers and mobile phones for a long time.The product has a watery lotion texture, melts into water upon application and absorbs quickly. After film-forming, it presents a refreshing matte effect without greasiness or stuffy feeling. The oil-free formula does not clog pores and is not prone to cause acne, suitable for oily, combination and normal skin. It is fragrance-free, alcohol-free, gentle and low-irritation, and can be used daily by sensitive skin. Apply evenly on the face and neck as the last step of morning skincare. It can not only provide sun protection during commuting, but also provide continuous light protection for more than 8 hours of screen exposure in the office. It is a full-scenario sunscreen suitable for urban office workers and people who stay up late.
