Product summary

We assess that "Sun Bum - Signature SPF 30 Sunscreen Face Stick" 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).

It contains good moisturizing ingredients and can double as a hydrating day cream. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.

Sunscreen filters

This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. The organic filters in the product are: octinoxate, homosalate and octocrylene. As for the mineral filters, this sunscreen uses both titanium dioxide and zinc oxide.
