Which ingredient is commonly used to absorb UV radiation in cosmetics?

Zinc oxide is commonly used in cosmetics as a physical sunscreen ingredient that effectively absorbs and reflects UV radiation. It plays a crucial role in protecting the skin from the harmful effects of both UVA and UVB rays. As a mineral-based ingredient, zinc oxide forms a barrier on the skin, which not only absorbs UV radiation but also helps to prevent sunburn and potential long-term skin damage.

While sodium lauryl sulfate is primarily a surfactant used for its cleansing properties, talc is known for its absorbent qualities and is often used in powders, and magnesium carbonate serves as a drying agent. These ingredients do not have the capability to absorb UV radiation effectively, making zinc oxide the appropriate choice for this function in cosmetic formulations.
