Wrinkle relaxers are injectable treatments that help reduce the appearance of wrinkles and fine lines by temporarily relaxing the muscles beneath the skin. The most well-known types of wrinkle relaxers are botulinum toxin injections, and we carry some of the leading brands. These treatments work by blocking the signals from the nerves to the muscles, preventing the muscles from contracting. As a result, the overlying skin becomes smoother and less wrinkled.
