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.

What the product description says
“Anti Oxidant Moisturizing Cream SPF30”
From product name

This product contains tocopherol. This ingredient help neutralize free radicals in skin. By doing so, they might be able to prevent early signs of aging (like fine lines and wrinkles), at least to some extent. These ingredients will not be able to "reverse" signs of aging. The biggest anti-aging effect in this product comes from sun protection. Sun damage is the main factor causing early signs of skin aging. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).

Butyrospermum parkii butterEffect: LowA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~2–2.9%
TocopherolEffect: LowPure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.15–0.55%
Lactic acidUnder-dosedEffect: MediumAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.2–0.75%

Good evidence

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: butyrospermum parkii butter, cocos nucifera oil.

Product summary

We are worried that "Kimberly Sayer - Anti Oxidant Moisturizing Cream SPF30" might not be able to provide reliable sun protection because it uses a single UV filter (zinc oxide) in a relatively weak concentration.

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

Sunscreen filters

This moisturizer 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

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here
