INCI - Full Breakdown
Zinc Oxide is a great physical sunscreen, meaning it deflects the UV rays. It’s the only natural mineral sun protector recommended by the FDA for babies. It’s good for sensitive skin because it’s less irritating than chemical sunscreens.
It has very nice spectrum protection. It helps to protect from UVA I, UVA II, and UVB and nowadays it’s the broadest range of sunscreen used in cosmetics. In other words, it’s brilliant in its league.
The negative side is that it can feel heavy on the skin. It can leave a slight whitish tint on the surface of the skin and some people may not like this. Keep in mind that it’s relatively easy to wash off, so it’s better to use water-resistant sunscreens if you are swimming.
Octinoxate is an effective sun protector that absorbs UV-B rays mostly. That means it can help to protect the skin from burns and from cancer. It’s also a solvent for other sunscreen components. This helps manufacturers to make products less oily.
Calendula Officinalis Flower Extract is used in medicine for hundreds of years. A small study shows that it can make skin firmer and more hydrated. There was also a slight improvement in elasticity of the skin. The component also heals wounds.
Ascorbyl Palmitate is a derivative of ascorbic and palmitic acids. It's a fat-soluble form of Vitamin C. It penetrates into the skin through cell membranes. Acts as an antioxidant. Due to its antioxidant properties, it is considered a rejuvenating vitamin. Controls the production of collagen in cells. Non-irritant at neutral pH.
