Sun protectionSPF 30 · 6 UV filtersBroad spectrum
This product offers a good level of protection against both UVB and UVA rays.
This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.
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.

Evens skin toneNot advertised by the brand · No ingredient credited for this claimStrong support

MoisturizingNot advertised by the brand · 10 ingredients credited for this claimGood support
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, butylene glycol.
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, c12-15 alkyl benzoate.

Product summary
The ingredient list suggests that "Piz Buin - Moisturising Sun Lotion - High SPF30" can provide reliable sun protection. It can protect from both UVA and UVB rays. This is great news because 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).
As a plus, this sunscreen uses some of the new generation UV filters (Tinosorb M). These filters are more stable and more gentle on the skin.
It also works as a moisturizer, so you do not have to use an additional hydrating product. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.
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.
