Our SPF Formulations offer sophisticated solar and environmental protection. Designed with every complexion in mind, these advanced Formulations imbue polished protection for a brilliant appearance.
What is Zinc Fusion Technology?
RATIONALE's proprietary Zinc Fusion Technology delivers sophisticated solar and environmental protection. When combined with Melanin and Iron Oxides, this powerful trio amplifies natural luminosity within the skin, helping to reduce the appearance of redness for a more even complexion.
Do RATIONALE’s SPF Formulations feature chemical or mineral UV Filters?
We have moved away from chemical UV Filters in our SPF Formulations as they can contribute to skin sensitivities. Rather, our SPF Formulations feature mineral UV Filters, which are known for their soothing properties.
What are the benefits of layering SPF?
Research indicates that 80% of facial ageing is caused by the sun. Therefore, we can never have enough protection. Laying various forms of protection—such as UV Filters, Antioxidants and Minerals—provides protection from the multiple wavelengths of light that accelerate skin damage.
What is the Solar Constant?
The Solar Constant refers to the total output of the sun’s energy that reaches Earth. It comprises Visible Light, which we can see; Infrared Radiation, which we feel as heat; and UV Radiation, which we can neither see nor feel.
Do I need to use all Formulations in #3 The Brilliance Collection?
We recommend using at least one Formulation from each of the Essential Six Collections for remarkable skin luminosity. However, those experiencing signs of solar and environmental damage may like to use more than one from The Brilliance Collection.
