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.

Moisturizing

Not advertised by the brand · 7 ingredients credited for this claim

Good support

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, caprylyl glycol.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

Product summary

Based on the ingredients included, we believe that "ISDIN - Photoprotector Hydro Lotion SPF50" can offer reliable sun protection. 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. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

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. The UV filters in this sunscreen are: tinosorb s 0.60% - 0.90%, avobenzone 2.10% - 2.60%, uvinul a plus 1.50% - 1.90%, uvinul t 1.40% - 1.70%, octocrylene 3.30% - 4.00% and ensulizole 1.20% - 1.40%.
