Collagen Stimulators: Poly-L-Lactic Acid and Calcium Hydroxyl Apatite

Facial Plast Surg Clin North Am. 2015 Nov;23(4):459-69. doi: 10.1016/j.fsc.2015.07.007.

Abstract

Over the last decade, many studies of the structural changes observed in the aging face (in bone, fat pads, facial ligaments, muscle, skin) have increased our understanding that facial rejuvenation is more complex and nuanced than simply filling lines and folds or cutting and lifting soft tissue and skin. This, in addition to the many new products introduced to the marketplace over the same period, has fueled the evolution of panfacial rejuvenation and restoration using fillers. This article discusses current techniques used with calcium hydroxylapatite and poly-l-lactic acid to safely and effectively address changes observed in the aging face.

Keywords: Calcium hydroxyl apatite; Collagen stimulators; Facial rejuvenation; Fillers; Poly-l-lactic acid.
