With the summer sun blazing and days under the rays getting longer, its not uncommon for our skin to feel tighter and dryer. Luckily, Three Ships best-selling Radiance Grape Stem Cell + Squalane Day Cream ($35) is back in stock now to help fight the summer-skin blues. The sustainable skin-care brand’s day cream has sold out seven times and boasts a 5-star rating amongst over 400 reviews. Here is all you need to know about the beloved beauty essential.

The cream’s formula is 100-percent plant-derived, vegan and certified cruelty-free, making it safe for sensitive skin. Derived from natural sugar cane and featuring grape stem cell extract, squalene and bark extract blend, the product combines natural ingredients to quench thirsty skin and enhance moisture retention long-term.

Grape stem cell extract, derived from the Gamay Teinturier Freaux grape, contains the powerful antioxidant anthocyanin, which inhibits free radicals while protecting the skin cells of the epidermis. The popular skin-care ingredient, squalane, boosts skin radiance by replenishing the skin’s natural lipid barrier and protecting the skin from external pollutants and irritants. Bark extract blend combines four different types of upcycled tree bark which promotes long-lasting hydration and enhanced skin elasticity through the use of powerful polyphenols.

As if the five-star ratings and all-natural formula weren’t enough, a customer testing survey revealed that 100-percent of participants said their skin felt hydrated after using and they would recommend to a friend, and 96-percent of participants said the cream absorbs into their skin with ease. Application is simple, too: Apply one pump of Radiance to clean, dry skin every morning.

From the carefully curated formula and the raving customer reviews, Three Ships Radiance Grape Stem Cell + Squalene Day Cream is undoubtedly a must-have for summer. But, you better add this product to cart now before it sells out again.
