Avobenzone (Cat No.: A000883) is a chemical sunscreen agent used in skincare products to absorb and block UVA rays, which contribute to skin aging and cancer. As a broad-spectrum filter, it protects the skin from long-wave ultraviolet radiation (320–400 nm). Avobenzone is often combined with other UV filters to enhance stability and effectiveness, as it can degrade when exposed to sunlight. It is commonly found in creams, lotions, and sprays. Generally well-tolerated, avobenzone may occasionally cause skin irritation or allergic reactions in sensitive individuals.
