Due to the properties of hyaluronic acid, once injected, it has an instant, visible, volumizing effect on the skin, and provides longer-term binding with water thereby increasing hydration. Unwanted folds and wrinkles can be “plumped up” to reduce their appearance, resulting in a smoother, more youthful-looking skin. There’s no preliminary allergy test required, and a treatment may take as little as 15 minutes. You can return to your daily activities immediately afterwards.
