 Restylane Silk has been safely and effectively used in rejuvenation and appearance of wrinkles in the face. This study seeks to investigate the safety and efficacy of the injectable device in the chest for similar effects. Participants will undergo three treatments with Restylane Silk and results will be measured clinically and with Optical Coherence Tomography an FDA-cleared non-invasive imaging device. Participants will receive randomized injections with the Restylane Silk product on half of the chest and will receive placebo injections on the other half. At the six-month period, participants will have the option to receive treatment with the product on the placebo side. At the 12-month period, participants may also elect for three additional touch-up treatments, which will not be counted as part of the study. If the chest is asymmetric in regards to wrinkles, the investigators will still proceed with the protocol because they are also comparing each side to itself prior to treatment, instead of simply comparing one side to the other.
