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 the product description says

“It is a physical sunscreen for daily use that is filled with 70% of water and covers your skin with a moist and clear layer, and the cream applies very uniformly and smoothly on the skin.”

Source: Walmart

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, butylene glycol.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: madecassoside, niacinamide

Asiatic acidKey activeEffect: HighAn active compound of Centella Asiatica plant extract. In combination with other active compounds of Centella Asiatica extract (asiaticoside, madecasosside and madecassic acid) asiatic acid has been shown to be helpful in wound-healing, restoring skin barrier function and supporting collagen production in skin. It can, however, itself be irritating~0.15–0.65%

AsiaticosideKey activeEffect: HighAn active compound of Centella Asiatica plant extract.

It can, however, itself be irritating~0.2–0.8%

It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

Concentration of 4-6% is better for helping with acne and balancing the sebum production~1.5–2.3%

Product summary

We assess that "PURITO - Comfy Water Sun Block" can provide reliable sun protection based on the ingredient list. 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.

Sunscreen filters

This product 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
