Sun protectionSPF 45 · 4 UV filtersBroad spectrum
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.

“Water Drench Hyaluronic Hydrating Moisturizer SPF 45”
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, saccharide isomerate.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, argania spinosa kernel oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: caprooyl phytosphingosine, caprooyl sphingosine, ceramide ap, ceramide eop, ceramide eos, ceramide np, ceramide ns
Anti-agingTocopherol, Ascorbyl palmitateStrong evidence

Product summary
We assess that "Peter Thomas Roth - Water Drench Hyaluronic Hydrating Moisturizer SPF 45" 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 also works as a moisturizer, so you do not have to use an additional hydrating product. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
