7% Ectoin + Hyaluronic Acid Milky Hydrating Serum

“One of the more recent launches from Paula’s Choice, their Ectoin 7% Booster features a potent dose of the eponymous, buzzy extremolyte, ectoin. What is an extremolyte, you ask? They’re powerful, naturally occurring protective elements found more and more frequently in soothing and hydrating skincare. These low-molecular-weight organic compounds are produced by extremophilic microorganisms to help them survive harsh conditions like high temperatures, UV radiation, and other environmental stressors. Read: deep hydration, moisture retention, and skin repair. Paired with multi-weight hyaluronic acid and glycogen, this milky, lightweight fluid is easy to layer and plays well with retinol or any other potent actives to help calm, hydrate, and soothe skin.”
