Product summary

We believe that "Piz Buin - Mountain Sun Cream SPF30 High Protection" can provide reliable sun protection based on the ingredients listed. 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).

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. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

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. The UV filters in this sunscreen are: tinosorb s 0.45% - 0.70%, avobenzone 1.60% - 1.90%, octisalate 4.70% - 5.80%, tinosorb m 0.75% - 1.10% and octocrylene 3.70% - 4.50%.

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 it to be medium. For a detailed overview of all potential irritants: click here

What can the product work for?

Sun protection

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.

butyl methoxydibenzoylmethane 1.6% - 1.9%

Irritation risk:

UVA I protection: UVA II protection: UVB protection: Photo stable: Ingredient type Organic

Avobenzone. An organic, or so-called "chemical" UV filter. Protects against both UVA and UVB rays. Needs to be combined with other filters in a formulation to be stable.

methylene bis-benzotriazolyl tetramethylbutylphenol 0.75% - 1.1%

Irritation risk:

UVA I protection: UVA II protection: UVB protection: Photo stable: Ingredient type Organic

Tinosorb M. A UV filter. Is effective against both UVA and UVB rays. It also provides some protection against visible light. It is photostable and can also be used to improve photostability of other sunscreen ingredients. Its physical properties help to create lightweight sunscreen formulations. It can leave a slight white cast. Unfortunately, it is not approved by the FDA (US) yet

octocrylene 3.7% - 4.5%

Irritation risk:

UVA I protection: UVA II protection: UVB protection: Photo stable: Ingredient type Organic

A weak sunscreen that protects against the sun rays that cause sunburn (UVB) and is somewhat effective against the UVA rays. It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen

Anti-aging

This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.

butyrospermum parkii butter 0.7% - 1.05%

Irritation risk: Comedogenicity: High

Concentration: Insufficient!

A 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

tocopherol 0.15% - 0.25%

Irritation risk:

Concentration: Insufficient!

Pure 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

Evens skin tone

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

What does the product description say?

Mountain Sun Cream SPF30 High Protection

Source: From product name

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

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).

trehalose 0.3% - 0.55%

Irritation risk:

Concentration: Effectiveness: HIGH

A sugar that attracts water to the upper layer of the skin

glycerin 2.5% - 3%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

cetearyl alcohol 0.25% - 0.45%

Irritation risk: Comedogenicity: Medium

Concentration: Effectiveness: MEDIUM

A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
