HA Touch-up

An HA touch-up uses the same class of material as other hyaluronic acid injections, but the purpose is contour: commonly discussed areas include a slightly recessed chin, a jawline that lacks definition, and hollow temples. For the material itself, see the hyaluronic acid entry; using it to soften etched-in lines such as nasolabial folds belongs to the HA filler entry.

Small, targeted injections add support and volume at specific points, which can change a profile line or make the transition between features look smoother. Because the body gradually metabolizes hyaluronic acid, the result is temporary, and in most cases the gel can be dissolved with hyaluronidase if adjustment is needed. It cannot make bone smaller or remove fat, and it does not replace structural options such as orthognathic surgery or implants.

Cross-linked hyaluronic acid gels come in different degrees of firmness: firmer gels are used where support is needed, such as the chin or jawline, while softer ones blend transitions, and the choice is the physician's judgment based on the area and the goal. A session usually begins with a consultation about the aesthetic goal, photographs for assessment, and cleansing and disinfection of the skin; many fillers contain lidocaine, and a numbing cream may also be applied.
