Neurotoxins, also known as wrinkle relaxers or muscle relaxants, are a popular non-surgical treatment. These injectable substances work by temporarily blocking the nerve signals that cause muscle contractions. By doing so, they effectively smooth out wrinkles and fine lines, particularly in areas like the forehead, between the eyebrows, and around the eyes.Neurotoxins not only minimize the appearance of existing wrinkles but also prevent the formation of new ones.
