Age-related volume loss; increased skin laxity, fat loss, redistribution, diminished support from underlying muscle and bone result in the observable and sometimes profound changes seen in the aging face. Aging also is associated with functional changes in the skin, such as dermal atrophy with diminished fibroblastic activity, decreased collagen production and altered elastin. came With the development of synthetic fillers, such ashyaluronans, calcium hydroxylapatite, poly-L-lactic acid, and silicone, it became possible to inject fillers specificallyinto different tissue layers.The emergence of fillers with superior lift capabilities, while still maintaining the desired position, opened the door to the concept of volumizing for achieving optimal aesthetic results in addition to more superficial filler placement. The past century has seen an explosion of development of new fillers and their global acceptance by a patient population that would rather look restored and younger without the trauma and downtime of surgery. Indeed, the introduction of non or minimally invasive injectable procedures represents a significant shift in the approach tofacial rejuvenation.
