Many patients have a poor understanding of how and when botox or fillers should be used. The facial lines can be divided into either dynamic or resting lines. Dynamic lines are lines that can be seen when you animate or move your face. Examples of such lines are forehead lines, glabellar lines, and crow’s feet. Dynamic lines occur because the underlying muscle moves and contracts. Botox is used to relax these muscles by disrupting muscle-to-muscle communication. Resting lines are lines that can still be seen when your face is at rest. Smile lines (nasolababial folds) and marionette lines are good examples. These lines occur due to loss of volume and sagging cheek tissue. As you inject Juvederm (or Restylane, Perlane, Radiesse) into these lines, you are making them less noticeable by decreasing the depth. For patients with deep nasolabial folds, an endoscopic mid-facelift or a layering technique of fillers may be a better option. Botox and fillers are simple office procedures that require little or no downtime.
