Glacier Water HA Serum

A hyaluronic acid serum formulated on a glacier water base instead of ordinary purified water. Hyaluronic acid works by holding water in place, so it does its job best applied to skin that is still slightly damp. At 50 ml this is a larger bottle than most serums, intended for twice-daily use rather than occasional. Apply to damp skin after cleansing and follow with a moisturiser to lock it in.
