Experience instant and long-lasting hydration that lasts up to 72 hours with the Skinstitut 1% Hyaluronic Complex Serum.

Starring four types of hyaluronic acid with different molecular weights, the formula works to minimise feelings of dryness and tightness. This nourishing effect is amplified with panthenol and pentavitin. Hosting protective properties, the treatment defends the skin barrier against environmental aggressors such as cold weather, heat and pollution, while simultaneously smoothing the appearance of fine lines.
