Sun protection

SPF 46 · 5 UV filters

Broad spectrum

SPF 46Broad spectrumChemical filtersNo white cast

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" sunscreen9%

HomosalateUVB Photo-stable A weak sunscreen that offers some protection against the sun rays that cause sunburn (UVB), but does not offer meaningful protection against 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. When used in low concentrations, helps to stabilize the product formulation7%

Butyloctyl SalicylateUVBA synthetic ester of salicylic acid that is used to help disperse pigments and boost effectiveness of sunscreen ingredients. It is able to absorb UV light (working as an organic, or chemical filter), but is not approved as a sunscreen ingredient on its own~5.7–7%

Anti-aging

Not advertised by the brand · Glycine soja seed extract, Tocopherol

Strong evidence

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.

Glycine soja seed extractEffect: LowAn emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.~0.75–1.1%

TocopherolEffect: Low, below effective dosePure 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~0.3–0.55%

Evens skin tone

Not advertised by the brand · Glycine soja seed extract

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).

Anti-oxidation

Not advertised by the brand · Haematococcus pluvialis extract, Glycine soja seed extract + 3 more

Moderate evidence

This product contains antioxidants (haematococcus pluvialis extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Moisturizing

Not advertised by the brand · Betaine, Fructose + 14 more

Good evidence

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: betaine, fructose.

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: glycine soja oil, c12-15 alkyl benzoate.

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~1.8–2.2%

InulinKey activeEffect: HighHelps attract water to the upper layer of the skin. Is claimed to support the growth of "good" bacteria in skin (as a "prebiotic"), but the research is lacking~0.45–0.7%
