This product uses a single UV filter (zinc oxide) in a relatively low concentration and might not be able to provide a reliable sun protection.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: cera alba, cocos nucifera oil.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).
