Benzophenone-5

Benzophenone-5 is a synthetic chemical compound used as a UV absorber in skincare formulations. It works by absorbing ultraviolet (UV) radiation and converting it into heat, which is then released from the skin. This mechanism differs from physical (mineral) UV filters, which sit on the skin's surface and scatter UV rays.As a chemical UV filter, benzophenone-5 is designed to integrate into the skin's upper layers, allowing for a more cosmetically elegant finish compared to mineral sunscreens. It is commonly found in broad-spectrum sunscreen products and sun protection formulations.

Benzophenone-5 functions as a chemical UV absorber by absorbing photons of ultraviolet light. When UV radiation strikes the ingredient, electrons within its molecular structure become excited to a higher energy state. The ingredient then releases this energy as heat, effectively dissipating the potentially damaging UV energy before it can harm skin cells.Because it works through absorption rather than reflection, benzophenone-5 integrates into the skin's stratum corneum (outer layer), creating a protective layer that requires even distribution across the skin for optimal effectiveness.

Apply benzophenone-5-containing sunscreen generously and evenly across all sun-exposed areas of the face and body at least 15 minutes before sun exposure. Reapply every 2 hours, or more frequently if swimming or sweating. For optimal protection, use in conjunction with other sun protection measures such as protective clothing, hats, and seeking shade during peak UV hours (10am–4pm).

Benzophenone-5 is generally well-tolerated in skincare formulations. Some individuals with sensitive skin may experience mild irritation; patch testing is advisable if you have a history of fragrance or sunscreen sensitivity.
