First manifestation of age, the installation of wrinkles is likely to impact the harmony of the face little by little. These folds begin by being barely visible on the surface of the skin and then become more marked and deep with time and the evolution of the sagging skin .
Two types of wrinkles must be differentiated since the treatment differs depending on:
- Expression or dynamic wrinkles originate from the repeated contraction of the muscles of the face when we speak, smile, frown or raise our eyebrows, for example. Over time, these dynamic wrinkles end up being visible even at rest. These are forehead wrinkles , frown lines, crow’s feet , perioral wrinkles (bitter lines or marionette lines) and chin wrinkles. It is here that the injection of botulinum toxin is indicated, since its action is based on the control of the targeted muscular contractions.
- Unlike dynamic wrinkles, static wrinkles are most often the consequence of skin aging: nasolabial folds, tear troughs, chin wrinkles, neck and décolleté wrinkles. Hyaluronic acid is the solution of choice to fill in these wrinkles.
