Beyond UV: Why 2025 Research Says Sunscreens Should Fight Blue Light and Infrared
Sun protection is expanding past UVA and UVB - a 2025 scientific review explains the blue-light and infrared gap your 'broad spectrum' label doesn't cover.
A 2025 scientific review on next-generation photoprotection argued that blue light (HEV) and infrared radiation contribute to photoaging and pigmentation, and that current commercial sunscreens largely fail to block infrared - calling for broader strategies that combine new UV filters, antioxidants, and biotechnology-derived ingredients.
Photoprotection researchers note that the term 'broad spectrum' addresses only the UV portion of sunlight, and that combining UV filters with antioxidants may be a more realistic route to covering visible and infrared exposure than UV filters alone.
Questions we get a lot
Does sunscreen protect against blue light?
Standard 'broad spectrum' sunscreen is rated for UVA and UVB, not visible blue light. A 2025 review noted that blue light (HEV) can contribute to pigmentation and photoaging, and that newer strategies pair UV filters with antioxidants and pigments like iron oxides to extend coverage. Check whether a product specifically claims visible-light protection.
Why don't sunscreens block infrared radiation?
According to the 2025 review, most current commercial sunscreens are formulated to absorb or reflect UV and largely fail to block infrared. The review argues that antioxidants and biotechnology-derived ingredients are being explored to address the infrared and visible-light gap.
What does 'broad spectrum' actually mean?
'Broad spectrum' is a UV-protection claim indicating a product guards against both UVA and UVB, not just UVB. It does not certify protection against visible blue light or infrared. The 2025 review highlights this gap and calls for broader photoprotection strategies.
