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: beeswax, butyrospermum parkii butter.

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).

Product summary

We are worried that "Salt & Stone - All Natural Sunscreen Lip Balm SPF of 3" might not be able to provide reliable sun protection because it uses a single UV filter (zinc oxide) in a relatively weak concentration.

Sunscreen filters

This lip product is a mineral sunscreen. It uses zinc oxide for sun protection. Zinc oxide almost never irritates the skin or stings eyes, but it can leave a white cast.

Irritation risk

This product does not contain known common irritants and is suitable for sensitive skin. We assess the overall irritancy of this lip product to be low. For a detailed overview of all potential irritants: click here
