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.

Product summary

We believe that "Peter Thomas Roth - Max Clear Invisible Priming Sunscreen Broad Spectrum SPF 45" can provide reliable sun protection based on the ingredients listed. 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 helps prevent early signs of aging.

Sunscreen filters

This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. These are the sun protection ingredients in this sunscreen: avobenzone 3.00% (declared), butyloctyl salicylate 2.70% - 4.00%, octisalate 5.00% (declared), homosalate 15.00% (declared) and octocrylene 10.00% (declared).

Irritation risk

This product does not contain known common irritants and is suitable for sensitive skin. We assess the overall irritancy of this sunscreen to be low. For a detailed overview of all potential irritants: click here
