Sun Bum Signature SPF 30 Sunscreen Lip Balm
Works for
Sun protectionSPF 30 · 1 UV filter · Broad spectrumWeak protectionLow zinc dose
This product uses a single UV filter (zinc oxide) in a relatively low concentration and might not be able to provide a reliable sun protection.
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.
MoisturizingSide benefit · Prunus amygdalus dulcis seed, Simmondsia chinensis seed oil + 9 moreWorks
This product can help soften the skin and reduce its moisture loss with emollients and occlusives: butyrospermum parkii butter, caprylic/capric triglyceride.
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
Based on the ingredient list, we assess that "Sun Bum - Signature SPF 30 Sunscreen Lip Balm" can provide reliable sun protection. 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).
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. Here are the exact UV filters in this sunscreen: avobenzone 2.00% (declared), octinoxate 7.50% (declared), octisalate 5.00% (declared) and homosalate 15.00% (declared).
Irritation risk
There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of it to be high. For a detailed overview of all potential irritants: click here
