The skin naturally loses collagen and hyaluronic acid as we get older, leading to a loss of elasticity, volume and plumpness to the skin. Not only can this emphasise fine lines and wrinkles, but it can also cause the skin to sag and become crepey and look less defined. Using an administered form of hyaluronic acid, dermal fillers can target these issues, leaving the skin looking younger, radiant, and more defined.
