Hyaluronic Serum

A concentrated hyaluronic acid serum that pairs high and low molecular weight molecules with purslane extract to provide immediate hydration and antioxidant protection. It’s a famously minimalist formula that sinks in instantly without any stickiness, making it an easy layer under heavier creams or makeup. The inclusion of purslane—a signature Sturm ingredient—helps soothe irritation, which is great for calming things down after a long flight or a day in the sun.
