As a daily protection, Solar Rx is designed to offer the maximum physical protection from UVA and SPF 30 for UVB burning rays without using a chemical sunscreen. Keys Solar Rx carries a UVB (UV Burning) rating of SPF 30+ and a UVA (UV Aging) of four stars using the EU rating system. It is important to note that 90% of all visible skin aging comes from UVA.

Solar Rx is both moisturizer and sunblock. It combines the healing soothing properties of Keys` Luminos moisturizer and adds a 20% concentration of uncoated nano-zinc oxide to provide a physical UVA and UVB blocking to protect against UV triggered Melanoma and Skin Cancer. Their nano-zinc oxide (ZnO) is uncoated to provide healing therapies associated with zinc oxide. The uncoated zinc has also proven to be anti-bacterial and antimicrobial and can reduce redness, rosacea, age spots and melasma. Solar Rx carries a EWG Skin Deep Rating of 0 (0 to 10 scale where 0 is best).
