title: Transdermal injection of Restylane SubQ for aesthetic contouring of the cheeks, chin, and mandible.
abstract: Initial experience in transdermal administration of Restylane SubQ for augmentation of the cheek and chin suggests that the product is easy to administer via this route and that it provides a stable aesthetic result. Local adverse reactions are consistent with those expected of an alloplastic filler material and appear to be related to the injection procedure/site rather than to the product itself. In the event of overcorrection or the appearance of superficial irregularities (nodules), any excess material can readily be removed by needle aspiration. Several measures can be taken to increase the likelihood of a satisfactory aesthetic outcome and minimize the risk of treatment complications with Restylane SubQ. One such measure is to deposit the product in small aliquots at multiple sites (using a multiple tunneling technique) to avoid pooling within the soft tissues. Treatment sites with poor soft-tissue cover pose a challenge because of the high risk of surface irregularities. In cheek augmentation procedures, Restylane SubQ should be placed below the zygomatic arch where the subcutaneous tissue is more fibrous, thereby providing a possible barrier to implant mobility. The chin appears to be particularly well suited to volume augmentation with Restylane SubQ because its dense fibrous tissue creates naturally occurring pockets for product placement. In summary, transdermal administration of Restylane SubQ is a convenient, noninvasive procedure for chin and cheek contouring and for rejuvenation of the mid and lower face.
