• Now Herpatch launches a new product: the first liquid patch that treats the symptoms of cold sores, with Beta Glucan. An invisible liquid patch, easy to apply (and removable with water), with a protective film that prevents the proliferation of the virus and has a triple action: • 1.- Promotes healing. Thanks to Glucan, it softens, protects, and hydrates the skin, promoting the healing process of the cold sore. • 2.- Protects against external aggressions, thanks to the sulfated polysaccharides of red microalgae, which help protect against sun exposure, with protective and moisturizing properties for the skin. • 3.- Creates a hostile environment, due to its zinc sulfate content, which has an astringent action, firms, tones, and strengthens the layers of the skin.
