WIMJ summary
This product offers a good level of protection against both UVB and UVA rays.
This sunscreen uses organic sunscreen filters. Organic fitlers usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.
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.
Organic filters
| Ingredient | UVB | UVA I | UVA II | Stability |
|---|---|---|---|---|

| homosalate | | | | |

What does the product description say?WIMJ summary
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, caprylyl glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: beeswax, squalane.
Potential irritants
| Ingredient | Irritancy | Skin Benefit |

| homosalate | | |

Avobenzone. A broad spectrum sunscreen meaning that it can protect against both UVA rays. Currently, it is the only sunscreen ingredient available in the US (approved by the FDA) with the peak absorbance within the UVA I range. It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen. When used in low concentrations, helps stabilize the product formulation
