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.

OctocryleneUVB Photo-stable 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~3.7–4.5%
OctisalateEthylhexyl SalicylateUVBOctisalate. A UV filter. It offers some protection against the sun rays that cause sunburn (UVB), but does not protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen~3.3–4%
Uvinul TEthylhexyl TriazoneUVB Photo-stable Uvinul T. A UV filter. Effective against UVB rays. It is photostable. Can increase water resistance properties of the sunscreen. Unfortunately, not approved by the FDA (US) yet~2.6–3.2%
Tinosorb MMethylene Bis-benzotriazolyl TetramethylbutylphenolUVBUVA Photo-stable 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~4.8–5.8%

Evens skin tone
Not advertised by the brand · Ascorbyl tetraisopalmitate
Strong evidence

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).

Ascorbyl tetraisopalmitateUnder-dosedEffect: MediumA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.2–0.35%
Moisturizing
Not advertised by the brand · Glycerin, Trehalose + 9 more
Good evidence

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).

Product summary

Based on the ingredients included, we believe that "Uriage - BARIÉSUN 100 EXTREME PROTECTIVE FLUID SPF50+" can offer 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.

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

Sunscreen filters

This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. The UV filters in this sunscreen are: tinosorb s 1.70% - 2.10%, avobenzone 2.00% - 2.50%, octisalate 3.30% - 4.00%, uvinul t 2.60% - 3.20%, tinosorb m 4.80% - 5.80% and octocrylene 3.70% - 4.50%.

Irritation risk

This moisturizer contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this moisturizer to be low. For a detailed overview of all potential irritants: click here
