Full lips are usually associated with health and youth and all kinds of positive attributes, whereas thin lips are associated with senility, weakness and frailness. Lip aging usually occurs relatively early in life beginning at around thirty years of age and manifests itself as supravermillion rytides or wrinkles above and below the vermillion borders, and a decrease in the volume of the lips.. This is due to thinning of the dermis and volume loss, respectively as well as loss of the white roll definition. Sophisticated yet gentle techniques using exclusive formulations can produce outstanding results in restoring lip volume, making more prominent the "cupids bow" height, and defining the white roll. When injected into the lips it can restore a more natural or fuller look to either the lower and/or upper lip. Restylane® is an exclusive formulation of vegetable origin, making it biodegradable and perfectly compatible with skin tissues. Extremely safe, it requires no preliminary testing and is particularly recommended for those with allergies to collagen. Embarking upon lip augmentation, the guiding principle for the surgeon who has a good artistic sense of the lips, is to achieve a look that is natural.
