PO:DL Barley Hyal-Some Water Bomb HydroMask(4ea) | 20-Layer Deep Hydration with Hyaluronic Acids & Liposome Technology | 100-Hour Moisture Retention | Non-Irritating, EWG Green Grade, Fragrance-Free

A two-piece hydrogel mask built almost entirely around hydration — ten different forms of hyaluronic acid, which is not an exaggeration but a count. Sodium hyaluronate, hydrolysed hyaluronic acid, plain hyaluronic acid, sodium hyaluronate crosspolymer, hydroxypropyltrimonium hyaluronate, potassium hyaluronate, hydrolysed sodium hyaluronate and sodium acetylated hyaluronate all appear in the list. They sit at different molecular weights, which is the point: smaller fragments travel further into the upper layers, larger ones hold water at the surface. Around them: niacinamide high in the formula, madecassoside and dipotassium glycyrrhizate for soothing, panthenol, adenosine, shea butter and barley seed extract. Water appears twice — once as water, once as glacier water, which the brand highlights. The cooling sensation comes from methyl diisopropyl propionamide, a cooling agent rather than a menthol derivative, which is why it feels cold without stinging. No fragrance, no essential oils, no acids, no actives that sensitise. For a mask this loaded, the irritant list is remarkably short. Best for: dry, dehydrated and sensitive skin; flights and heated rooms; the evening after a long day outdoors.
