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.

Evens skin tone
Side benefit · No ingredient credited for this claim
Works well

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).

Moisturizing
Side benefit · Ethylhexyl palmitate, Caprylic/capric triglyceride + 3 more
Works

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

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 assess that "Sun Bum - Signature SPF 50 Sunscreen Lotion" can provide reliable sun protection based on the ingredient list. 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).

Its formula is also hydrating, so you might not need an additional moistruizer during the day. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

Sunscreen filters

This is a "mixed" sunscreen in the sense that it uses both mineral and organic (so-called "chemical") sun filters. Here are the organic filters this product uses: octinoxate, octisalate and octocrylene. As for the mineral filters, this sunscreen uses zinc oxide.

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 moisturizer to be medium. For a detailed overview of all potential irritants: click here
