This product can help soften the skin and reduce its moisture loss with emollients and occlusives: dimethicone, cyclopentasiloxane.
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).

Same as oxybenzone. Protects in the UVB and short UVA range. In small concentrations, used to stabilize product formulation. Can be irritating. Is shown to be harmful to coral reefs - consider avoiding bathing in coral reef areas when wearing a product with this ingredient. It can penetrate the skin and get absorbed into bloodstream faster than other popular filters available in the US. The study that produced this finding did not address any potential health effects of the absorption

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