Homosalate is a chemical compound commonly used in sunscreen products. It functions as a UV filter, helping to absorb and block harmful ultraviolet rays from the sun, thereby protecting the skin from sunburn and long-term damage. This ingredient is often combined with other UV filters to enhance the overall effectiveness of sun protection. While generally considered safe for topical use, some individuals may prefer to avoid it due to concerns about potential skin irritation or environmental impact. Always check product labels for specific ingredient information.
