This product does not offer good protection against UVA rays.

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.

Titanium Dioxide Mineral UVBUVA2 Photo-stable Works as a UV filter when used in high concentrations. It is photostable and is effective mostly against the UVB light, with some protection in the UVA range. In small concentrations, used for its ability to improve the color of cosmetic products. Is usually well tolerated by the skin~2–3%
Zinc Oxide Mineral UVBUVA Photo-stable A broad spectrum sunblock (protects from both UVA and UVB rays). Is suitable for most sensitive skins. In small concentrations, can be used as a colorant~1–1.5%

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.

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: isopropyl myristate, oenothera biennis oil.

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1.3–1.9%

Cucumis sativus fruit extractEffect: Low, below effective doseMight be somewhat helpful in reducing hyperpigmentation and neutralizing free radicals but its typical concentration in a product is too low for having an effect~1–1.5%

Product summary

We do not recommend "Coola - Mineral Matte SPF30 Cucumber" because it does not provide good UVA protection. UVA sun rays don't burn the skin, but they still lead to photoaging and hyperpigmentation.

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream.

Sunscreen filters

It is a mineral sunscreen. It uses titanium dioxide for sun protection. Titanium dioxide 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 it to be low. For a detailed overview of all potential irritants: click here

Price
