Investigating Age Dependence of Fibroblast and Extracellular Matrix Responses to Cross-linked Hyaluronic Acid Filler in Human Skin
Investigating Age Dependence of Fibroblast and Extracellular Matrix Responses to Cross-linked Hyaluronic Acid Filler in Human Skin
The purpose of the study is to investigate the impact of the injection of dermal filler on the quality of the skin dermal extracellular matrix in persons between the ages of 30-50 years. The quality of the dermal extracellular matrix will be assessed following injection of dermal filler compared to injection of saline vehicle.
