Sun protectionSPF 50 · 8 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.
Evens skin toneNot advertised by the brand · 1 ingredient credited for this claimStrong support

MoisturizingNot advertised by the brand · 11 ingredients credited for this claimStrong support
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, butylene glycol.
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, c12-15 alkyl benzoate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, panthenol
Anti-blemishNot advertised by the brand · 1 ingredient credited for this claimStrong support
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

Product summary
Based on the ingredients included, we believe that "Altruist - Sunscreen Fluid SPF50" can offer reliable sun protection. 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).
This moisturizer should also be hydrating enough to use without an additional moisturizer during the day.
