Avobenzone
Avobenzone is a key organic compound widely used as a broad-spectrum UVA filter in sunscreens and cosmetic products. Its primary function is to absorb harmful UVA rays (320-400 nm), which are responsible for skin aging, wrinkles, and long-term DNA damage. Unlike UVB blockers, avobenzone specifically protects against deep-penetrating UVA radiation, making it an essential ingredient in many sun protection formulations. To ensure effectiveness, it is often combined with UVB filters like octinoxate for full-spectrum defense and stabilized with compounds like octocrylene or antioxidants to prevent photodegradation. Beyond sunscreen lotions, avobenzone is incorporated into daily skincare products such as moisturizers, foundations, and anti-aging creams to provide consistent UV protection. While generally recognized as safe by regulatory bodies like the FDA and EU, it can degrade when exposed to sunlight unless properly stabilized and may cause irritation in sensitive individuals. For improved photostability, modern formulations frequently pair avobenzone with advanced filters like Tinosorb or Mexoryl.
