Hyaluronic acid serum vs injection fillers?

Hyaluronic acid serums are great for adding hydration and mildly plumping your skin. However, the hyaluronic acid will not penetrate beneath the skin and add volume in the way that dermal fillers do. Serums will make your skin look brighter and smoother but will not fill in lines or folds. Dermal fillers are precisely placed with a cannula or needle and last 1-2 years in the tissue. With regard to your hands, Voluma and Radiesse both work very well for covering up skeletal or very thin hands. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Topical hyaluronic acid serums doesn't have the same effect as injectable, if it did, nobody would get the injectable fillers.  Apply both topically and with injection give an improved apperance of wrinkles and fine lines.  Best, Dr. Emer.

Topical products will NOT produce any long term (actually more than few hours) effect.  The dark circles around eyes are usually due to hollowness. For that, direct filler injection the hollow area will be effective. See an oculoplastic specialist.
