Using sunscreen is a preventive measure to protect the skin from the harmful ultraviolet (UV) radiation of the sun. While sunscreen offers numerous advantages, such as preventing sunburn and premature aging, it also has certain drawbacks, including stickiness, potential skin irritation for certain skin types, and some ingredients being absorbed into the body, etc.

Avobenzone is a common ingredient in chemical sunscreens. Unlike other chemical sunscreen ingredients that only protect against sunburn-causing UVB rays, Avobenzone also shields the skin from UVA rays, which contribute to premature aging and skin cancer.
