The bitterness folds are lines which start from the corner of the mouth and descend towards the chin: their progression is gradual and inescapable.

These are the most ageing lines for the face, and give the impression of an ill-temper.

Causes of bitterness folds

Several factors lead to the appearance of these lines :
– The contraction of the facial skin muscles, notably the DAO muscle which pulls the corners of the lips downwards.

– Skin sagging and the ptosis (fall) of lower internal fat.

– The loss of support offered by the fat around the edge of the lips, and bone ageing.

Aesthetic treatment for bitterness folds

Hyaluronic acid

Depending on the severity of fold, a moderately reticulated Retylane type hyaluronic acid or a strongly reticulated Restylane Perlane type acid will be used. The injection is administered to the fold, and in an imaginary triangle placed under the labial commissure to give support to the edges of the lips, and to gently lift them.

The product stays in place between eight months and two years, depending on the severity of the fold, the age of the patient and the product used.
For certain uses, or where there is significant sagging, it is only possible to improve the appearance of the fold, rather than to correct it. In this case, the sagging must be treated using a hyaluronic acid lift (the vector technique).
