Avobenzone is a synthetic ultraviolet absorber, which is a good UV-A (>320nm) ultraviolet absorber. It can block UVA at full wavelength (320-400nm). It is an efficient broad-spectrum oil-soluble UVA filter. It can provide all UVA and UVB protection when combined with other UVB sunscreen agents to prevent skin cancer caused by light.
