Formula review

WIMJ summary

This product offers a good level of protection against both UVB and UVA rays.

It is a mineral sunscreen. In other words, it contains non-organic UV filters. It will probably not sting your eyes but might leave a white cast.

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.

What does the product description say?
"What’s more, Artemisia Cailaris Extract acts as an effective defence against other external aggressors such as fine dust."
WIMJ summary

This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.

These ingredients in the product might also be helpful for reducing and preventing fine lines, wrinkles, and skin elasticity, even though there is no conclusive evidence for their effectiveness: centella asiatica extract.

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: cyclomethicone, glycerin.

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: cyclomethicone, isododecane.

WIMJ summary

This product contains antioxidants (centella asiatica extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
