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 · Butyrospermum parkii butter
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.

Moderate evidence

This product contains antioxidants (chitosan, vaccinium macrocarpon seed oil) 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.

Good evidence

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: beeswax, butyrospermum parkii butter.

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 "KLENSKIN - Broad Spectrum SPF 50 Reef Safe Lip Balm" 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).

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. Here are the exact UV filters in this sunscreen: avobenzone 2.30% (declared), octisalate 4.30% (declared) and homosalate 9.20% (declared).

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
