This product offers broad spectrum sun protection, but it is weak. We recommend to use a broad spectrum sunscreen with at least SPF 30.
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.

“Keep skin safe in the sun with Piz Buin Hydro Infusion Sun Gel Cream SPF 15 , a water-resistant sun lotion formula that works to protect and hydrate sun-stressed skin.”
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: dimethicone, glycine soja oil.

Product summary
"Piz Buin - Hydro Infusion Sun Gel Cream SPF 15" offers broad spectrum protection. It means that it protects from both UVA and UVB rays (you can remember UVB as "burning" sunlight - they cause sunburn. You can remember UVA rays as "aging" - they do not lead to sunburn, but they cause photodamage and contribute to early signs of skin aging and hyperpigmentation). On the negative side, the SPF of this moisturizer is not high enough. We recommend to use a sunscreen with at least SPF 30 daily.
This moisturizer should also be hydrating enough to use without an additional moisturizer during the day.
Sunscreen filters
This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. Here are the exact UV filters in this sunscreen: tinosorb s 2.00% - 2.40%, avobenzone 3.10% - 3.80%, homosalate 6.30% - 7.70% and octocrylene 4.40% - 5.40%.
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here
