As we age, our lips age, too.
They deflate and sag as a result of many years of constant movement and folding caused by the contraction of the underlying muscles of the lower face and lips, in particular the orbicularis oris muscle. This inevitable process occurs during pouting, smiling, laughing, yawning, or simply talking. All of these movements happen thousands of times per day. In addition, forces of gravity, sun exposure, smoking and the decline of collagen and elastin production after age 30 result in the loss of youthful appearance in one of our most attractive facial features, our kissing lips.
