Jawline contouring for men

The 'mandibula de diamante' is a technique for injecting the mandibular line and chin in men to make the lower part of the face squarer and wider, in order to make it more virile. The result is reminiscent of the tip of a diamond, hence the name. These strong, angular features enhance sex appeal and give character and attractiveness to the face.

Aesthetic criteria

The lower third of the aesthetically ideal male face is wide and characterised by a broad, square, angular chin and a well-defined, projected, angular mandibular angle with an opening of around 120° (the male angle is slightly more closed than the female). The virility of the male face is essentially given by the lower third.

♦ The chin
The chin is an essential part of the lower third of the face and increases its attractiveness. Its shape, projection, rotation and height are determined by bone structure, muscles and fat, but can be modified by hyaluronic acid injections.
♦ The mandibular line
The jawline extends from the chin to the mandibular angle. The lack of definition in this area may be genetic or linked to ageing: over time, the bone resorbs and the tissues sag, making the jawline less clear.
♦ Mandibular angle
The prominence of the mandibular angle is important for a youthful, attractive lower third of the face. Its projection gives character to the face.

La Mandibula de diamante

Hyaluronic acid injections are the first-line treatment for shaping the diamond mandible. The surgical equivalent is the fitting of prostheses.

Injections are carried out using a cannula and needle.
The needle technique is used to inject boluses of hyaluronic acid deep down (in contact with the bone) to support the structures.
The cannula technique is used to give volume and definition. The product is injected deep into the subcutaneous tissue.
The injection session lasts around fifteen minutes and no social eviction is necessary, so you can resume your usual activities immediately.

The treatment aims to create :
♦ A more defined mandibular angle: the injection of hyaluronic acid at the mandibular angle gives a clear definition between the neck and the face and gives power to the face.
♦ A straight jaw: injection of hyaluronic acid along the mandibular line defines the line and lifts drooping tissues.
♦ A wide, square chin: injecting hyaluronic acid into the chin improves the proportions of the face and gives a slightly 'more athletic' character to the lower third of the face.

Results and follow-up

Depending on the desired result and the anatomy of each patient, the number of syringes used varies: three to fifteen syringes are needed for the face.
The result lasts about a year.
