Avobenzone works by absorbing UVA radiation and converting it into less harmful infrared radiation (heat), which is then released from the skin. This conversion process helps prevent the penetration of UVA rays into the skin, thereby reducing the risk of skin damage and other related health issues. However, avobenzone is known to degrade when exposed to sunlight, losing its effectiveness over time. To counteract this instability, formulators often combine it with other ingredients that can stabilize it, such as octocrylene.
