Circadia Light Day Sunscreen Broad Spectrum SPF 37
Circadia Light Day Sunscreen Broad Spectrum SPF 37 is a lightweight, fast-absorbing daily sunscreen that offers broad-spectrum protection with a non-greasy finish.
Its formula includes antioxidant ingredients such as Lipochroman-6™, Preventhelia™ and grape cell extract, which help defend the skin against environmental stress and the visible effects of sun exposure.
It is made for every skin type and for every day.
Why we love it
The best sunscreen is the one you actually put on every morning. Light Day absorbs quickly and leaves no greasy film, so it disappears into your routine. We like the antioxidants in the formula, which add a second layer of defence on top of the broad-spectrum protection.
