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.

Strong evidence

This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).

Moisturizing

Good evidence

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: dimethicone, dimethiconol.

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

Based on the ingredients included, we believe that "CoTZ - Face Natural Skin Tone SPF 40" can offer reliable sun protection. We love that it can protect from both UVA and UVB rays (not all sunscreens with SPF ratings give UVA protection. UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

Sunscreen filters

This sunscreen is a mineral sunscreen. It uses titanium dioxide and zinc oxide for sun protection. Both titanium dioxide and zinc oxide almost never irritate even the most sensitive skin and eyes, but 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 sunscreen to be low. For a detailed overview of all potential irritants: click here
