Collagen Filler - Does It Really Work?
the doctors on here seem to univerally say that collagen filler is old technique to improve lips and face lines. why then do so many skin care products have collagen and say collagen filler works? Like L'oreal Collagen Filler Eye. The L'oreal web site says in consumer testing, crow’s-feet decreased by 20% after four weeks, and 68% saw dark circles reduced in four weeks. So confused!
