Definitions

  • the present invention relates to devices for altering the appearance of the body or of the face.
  • the tissue made up of the skin, the skin muscles and, in general, a layer of fat becomes wrinkled because its overall surface area is too great in comparison with the region it is covering. This can be due to a hollowing or thinning of the face and/or the neck or to a phenomenon involving a change to the tissue.
  • the tissue weakens. This phenomenon, known as ptosis, can be associated with a relaxation of certain points of attachment of the skin. The surface drops downwards under gravity.
  • the tissue of the skin is tightened by a filling-out of the face and/or neck.
  • the filling-out may, for example, be the result of a weight gain or of an upsetting of circulation, for example lymphatic, functions, or of certain glands such as the thyroid.
  • the underneath of the chin is often affected by the second phenomenon, leading to unsightly effects that are almost impossible to treat without resorting to cosmetic surgery.
  • the front of the neck is often affected by the first phenomenon, with an unattractive folded appearance developing. This phenomenon may be the result of weakening.
  • the third phenomenon can be fairly significant in some instances, going so far as to limit or completely remove the curve of the neck, thus impairing the overall look of the head and neck region.
  • the second phenomenon may more particular affect the regions near the jawbones, including the outline of the mouth, and the cheeks, the weakening not being the same everywhere, being notably more pronounced between fairly distant muscle anchor points. This is why it affects the jawbone region more than it does the chin region, accentuating the visual effect on the oval of the face.
  • the third phenomenon may affect the entire face, except generally the forehead. It may give the eyes a puffy appearance, fill out the cheeks, and accentuate the nasogenian crease. It is very difficult to. treat these defects using conventional cosmetic approaches.
  • Cosmetic surgery techniques such as neck and face lift or cosmetic medicine such as the filling of fine lines and wrinkles, liposuction, heat treatment, laser skin tightening or Botox injections provide only partial solutions.
  • they often cause fear and apprehensivcness because of their invasive nature and because of the discomfort they can cause; these methods arc generally not considered to be acceptable solutions by people awaiting treatments for these forms of ageing.
  • a coloured or concealing coating such as a foundation
  • the technique that involves pulling the skin to reshape it is known.
  • the hair may be pulled back and fastened in a plait, a ponytail or a bun for example. That pulls on the skin and is quite effective at pulling the skin around the eyes but still remains fairly ineffective in improving the appearance of the neck and most of the surface of the face.
  • Figure 1 depicts a film stuck at one end near a region with wrinkles, which region is delimited by dotted lines, and which is then pulled and stuck down at the other end to an anchorage region near the temples.
  • the tensile force applied to the wrinkly region causes an elastic reaction force which is transferred to the anchorage region.
  • the forces oppose one another and the skin forms folds under the film. The folds that are formed extend beyond the film, as illustrated.
  • the pull that has to be applied in order to lift the skin in the region of the jawbone requires an anchor point near the cheekbones in order to create a vertical pull.
  • the folds that form in the intermediate region between the jawbone and the cheekbones by sticking a film here are highly visible.
  • the aforementioned first phenomenon also occurs on the entire front face of the neck. It may be very pronounced in the region of the sternal notch which may appear as one of the most wrinkled regions. When the neck is not stretched, the heads of the sternocleidomastoidien muscles are relaxed, making the folds in the region of the sternal notch and possibly of the Sedillot triangle even more prominent.
  • the ageing of the neck also gives rise to effects corresponding to the second phenomenon and which may become very pronounced. These are perceived as one of the greatest signs of ageing. Sagging of the skin and of the tissue situated immediately under the chin is noted, thus preventing the chin from appearing straight. In addition, it leaves the sternocleidomastoidien muscles protruding, as well as the two external jugular veins, even when these are not under tension.
  • Using a film to combat the second phenomenon in the neck region entails pulling upward or at an angle in the direction away from the chin.
  • An anchor point in the mastoid region can be selected to compensate for the elastic return force of the skin and the force of gravity. In both cases, the result is accompanied by the creati on of unattractive folds.
  • the folds may adopt various shapes according to the pull applied and the strength of the skin. A low pulling force combined with strong skin causes only a few stretched out folds. That is because the lines of traction extend fairly far beyond the film. A weak pulling force combined with skin of low resistance causes extensive folding. This is because the traction lines do not extend far beyond the ffitlL
