As you mature, your skin will naturally begin to change. Over time, collagen production slows, which can lead to less overall elasticity in the skin. This can cause fine lines and wrinkles to develop, especially in areas that habitually crease as a result of facial expressions you make. Frowning can cause lines to develop between your eyebrows and around the sides of your mouth. If you'd like to smooth or even prevent these lines, Botox treatment can help.
