The Anua Heartleaf 70 Calming Collagen Mask offers targeted skincare benefits through a carefully formulated sheet mask system. Each mask in this 4-pack contains heartleaf extract at a 70% concentration, known for its soothing properties that calm irritated skin and reduce redness. The addition of collagen enhances skin elasticity and hydration levels, creating a tightening effect that can visually diminish fine lines. These sheet masks are made from soft, breathable material that comfortably conforms to the contours of the face while allowing effective ingredients to penetrate deeply. The formulation is suitable for various skin types seeking relief from sensitivity or environmental stressors. Each individual mask contains about 23 ml of essence for complete coverage and extended treatment duration. The heartleaf component, derived from Houttuynia cordata, provides antioxidant benefits, while collagen supports the skin's moisture balance. The application typically lasts 15-20 minutes, during which the skin can absorb the valuable compounds. The masks are individually packaged to maintain freshness and efficacy. This product focuses on a calming skincare experience without strong fragrances or irritating additives, making it suitable for regular use in comprehensive skincare routines.
