Naturally blue-hued, the Dr.Althea Aqua Blue Hydration Mask (4 Pack) treats dry, dull skin to quenching moisture that lasts up to 24 hours. Made from tannin-rich oak tree fibres, this easy-adhere mask delivers a blend of nourishing ingredients to the skin, supporting a refreshed glow. Getting to work on areas of dryness are hyaluronic acid and Centella asiatica, a hydrating duo that help attract and retain moisture for a smooth, soothed skin barrier. Meanwhile, allantoin reduces the look of redness to support a more balanced tone with a brighter appearance, making this mask the perfect weekly treatment or whenever your skin needs an extra boost.
