The “square-jawed” look is usually the result of overdeveloped masseter muscles which are attached at the angle of the jaw and control mastication. Whilst in men this is a desirable feature of emasculation, the ladies will prefer a more slimming, triangular look. This can be achieved by injecting muscle relaxant in the enlarged jaw muscle. The effect will be a smooth, heart-shaped jawline appearance with softening of the contour of the lower facial area. The procedure is completely painless, the effects lasting 8-12 weeks.
