Zinc oxide is a physical UV filter, meaning it sits on top of the skin and acts as a barrier, reflecting and scattering ultraviolet (UV) radiation away from the skin. Unlike chemical sunscreens, which absorb UV rays and convert them into heat, zinc oxide works by blocking both UVA and UVB rays from penetrating the skin.
Physavie is specifically designed to protect against IR-A radiation. It works by reducing the production of heat-shock proteins (HSPs), which are triggered by heat and can lead to skin damage. By mitigating the effects of these proteins, Physavie helps prevent the breakdown of collagen and elastin, maintaining skin structure and firmness. It also has antioxidant properties that help neutralize these free radicals, protecting the skin from oxidative damage and maintaining its youthful appearance.

Niacinamide has potent anti-inflammatory properties, making it effective in soothing irritated skin. This is particularly useful in sunscreens, as UV exposure can trigger inflammatory responses in the skin, leading to redness, swelling, and other forms of irritation.
Dimethyl Methoxy Chromanol helps protect essential cellular structures, including lipids, proteins, and DNA. This protection is crucial in preventing the degradation of these molecules, which can result in premature aging, loss of skin elasticity, and the formation of wrinkles.
