Why are injectables so popular? Injectables are a safe alternative to traditional plastic surgery because people do not have to go under general anesthesia to have them. Injectables allow a practitioner to add volume in parts of the face to optimize the ‘golden ratio.’ Beauty is more scientific than you think. We perceive people as beautiful because of the symmetry and proportions of the eyes to the forehead, lips to nose, etc. Injectables are a safe way to optimize your ‘golden ratio’.
