Lancaster Beauty Sun Protective Water SPF50
Works for
Sun protectionSPF 50 · 7 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.
Anti-agingSide benefit the brand mentions · Tocopherol, Lactic acidWorks well
“The fine mist delivers broad-spectrum protection, helping to defend against the sun’s UVA and UVB rays.”
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.
Evens skin toneSide benefit · Bifida ferment lysate, Lactic acidWorks well
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-oxidationSide benefit · Dimethylmethoxy chromanol, Bifida ferment lysate + 1 moreWorks well
This product contains antioxidants (dimethylmethoxy chromanol) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
MoisturizingSide benefit the brand mentions · Diisopropyl sebacate, Diisopropyl adipate + 7 moreWorks
“The perfect pool-side companion, this lightweight and refreshing ‘water’ leaves skin feeling intensely moisturised and smooth (never greasy or oily!) with glycerol, while the brand’s Tan Activator Complex harnesses buriti oil to safely boost natural melanin production in preparation for a faster, longer-lasting tan.”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin.
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
We believe that "Lancaster - Beauty Sun Protective Water SPF50" can provide reliable sun protection based on the ingredients listed. 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).
It contains good moisturizing ingredients and can double as a hydrating day cream. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.
