Avobenzone (UVA filter) and octocrylene, octinoxate and octisalate (UVB Filters)
Avobenzone is a UVA filter. Unlike most other organic UVA filters, it provides broad-spectrum protection, including the longer wavelength UVA-I (340—400 nm).
Most UV radiation that reaches Earth is in the form of UVA. Damaging UVA rays penetrate the epidermis and dermis more deeply than UVB rays. Clinical studies have demonstrated that chronic exposure to UVA can cause structural cell damage and possibly even lead to cancer. UVA rays damage the collagen and elastic fibres that give skin its shape, definition and suppleness. Exposure to UVA rays leads to wrinkling and, eventually, premature skin aging.
When combined with UVB filters, it is possible to formulate a skin care product that provides broad-spectrum skin protection and helps prevent the formation of fine lines, wrinkles, age spots and potential skin cancer.
