SPF 50Broad spectrumChemical filters

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.

Anti-aging
Not advertised by the brand · 1 ingredient credited for this claim
Strong support

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.

Tetrahexyldecyl ascorbateUnder-dosedEffect: HighBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~0.15–0.65%

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).

This product contains antioxidants (camellia sinensis extract, punica granatum 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

Good support

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, dimethicone.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Product summary

We believe that this product can provide reliable sun protection based on the ingredients listed. 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).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

Sunscreen filters

This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. The organic filters in the product are: polysilicone-15. As for the mineral filters, this sunscreen uses both polysilicone-15.

Irritation risk

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this sunscreen to be low. For a detailed overview of all potential irritants: click here
