Sun protectionSPF 50 · 5 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.

This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).
Anti-agingNot advertised by the brand · No ingredient credited for this claimStrong support
This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.
MoisturizingNot advertised by the brand · 7 ingredients credited for this claimGood support
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": sarcosine, sodium hyaluronate.
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 "ACO - Ultra Light Sun Face Fluid SPF 50+" 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 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).
Sunscreen filters
This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. The UV filters in this sunscreen are: tinosorb s 1.40% - 1.70%, uvinul a plus 3.60% - 4.40%, octisalate 2.60% - 3.10%, uvinul t 1.70% - 2.00% and tinosrob a2b 2.40% - 2.90%.
