Circadia Light Day Sunscreen SPF 37 is a lightweight, non-comedogenic daily sunscreen built for people who want broad-spectrum UV protection without the heavy, pore-clogging texture that makes most sunscreens feel like a burden. It absorbs completely clear on all skin tones, works as a seamless base under makeup, and delivers far more than basic sun protection. This formula carries a subtle, citrus-adjacent scent from its botanical extracts.
Key Benefits
Broad-Spectrum UV Defense A chemical filter trio of avobenzone (3%), octinoxate (7.5%), and octocrylene (2.8%) absorbs both UVA and UVB rays, shielding skin from the two main drivers of photoaging and sun damage.
Enhanced UV Filter Stability SolaStay technology stabilizes avobenzone, which is known to degrade with sun exposure, keeping the UV filters performing consistently throughout the day rather than losing efficacy within hours of application.
Triple Antioxidant Defense Against Free Radicals Lipochroman (dimethylmethoxy chromanol) is a powerful antioxidant shown to neutralize oxygen, nitrogen, and carbon-centered free radicals, addressing a broader range of environmental oxidative stress than vitamin C or vitamin E alone.
DNA-Level Photoaging Defense Diaminopropionoyl tripeptide-33 helps reinforce the skin’s response to UVA-induced damage, supporting the processes that protect against long-term photoaging at the cellular level.
Antioxidant Botanical Complex A blend of grape fruit cell extract, citrus peel extracts, apricot fruit extract, and rosewood extract delivers additional antioxidant support, helping to buffer skin against pollution and blue light oxidative stress throughout the day.
