Broad-spectrum UV filters
Broad-spectrum UV filters are ingredients in sunscreens and daily skincare that shield skin from both UVA and UVB rays. They help prevent visible signs of sun damage such as premature ageing, pigmentation and loss of firmness. In the UK they are a must-have for year-round protection, even on cloudy days.
How it works in skincare
In cosmetics and skincare, broad-spectrum UV filters work by either absorbing ultraviolet radiation and converting it into harmless heat or by reflecting and scattering the rays away from the skin. Formulators in the UK combine several filters to achieve balanced UVA and UVB coverage while maintaining elegant textures that blend invisibly. These ingredients are carefully regulated under UK and EU cosmetic law to ensure safety and efficacy in everyday moisturisers, primers, foundations and dedicated sun-protection products.

Where it comes from
Broad-spectrum UV filters are primarily synthetic mineral or organic compounds developed in laboratories. Some modern filters are inspired by or stabilised with naturally derived plant-based antioxidants, though the active filtering molecules themselves are created through precise chemical synthesis to meet strict UK and EU safety standards.
