Asymmetrical lips: what’s the solution?
Written and reviewed by Dr Bernard Hayot, ophthalmologist, RPPS 10003926226.

Why are my lips asymmetrical?
Lip asymmetry, whether it is a difference between the volume of the lower lip and that of the upper lip, or a side-to-side inequality between the right and left halves of the mouth, can be observed from an early age. The asymmetry is then innate, congenital in origin, and is sometimes associated with an asymmetry of the jaw or of the teeth.
Lip asymmetry can also appear after a trauma or certain neurological or vascular events, such as a stroke or some conditions affecting the facial nerve.
Physiological ageing, for its part, leads to a loss of structural quality in the tissues, which can thin the lips and progressively alter their contours. This can result in lip asymmetry over time. Factors that accelerate natural ageing, such as an unbalanced diet, smoking, stress or chronic lack of sleep, are likely to encourage imperfections of the lips.
Hyaluronic acid to restore symmetrical lips
Hyaluronic acid is a molecule naturally present in the body, and particularly in the skin, where it maintains hydration and tone. As well as its revitalising properties, hyaluronic acid has a volumising effect that makes it highly effective for reworking the volumes of the face, and therefore of the lips.
Injected with very fine needles, it plumps the lips and alters their volume with the great precision now made possible by refined dosing and by the development of hyaluronic acids with different degrees of cross-linking.
To correct asymmetrical lips, Dr Hayot carries out a meticulous analysis of their characteristics. This allows him to determine which micro-areas need reshaping and which require added volume.
What are the benefits of hyaluronic acid for the lips?
Because hyaluronic acid is naturally present in the body, it is gradually and completely resorbed. This is intended to ensure perfect physiological tolerance and natural, discreet, reversible results.
The effects of hyaluronic acid are temporary and remain stable for 6 to 12 months on average. The injections can then be repeated without restriction, which makes it possible to maintain the desired appearance of the lips.
Injecting hyaluronic acid is also a simple medical procedure with very few constraints. It is virtually painless, lasts between 15 and 30 minutes on average, requires no anaesthetic and involves no time away from social life. In a few cases, slight swelling may appear afterwards, but the after-effects are generally straightforward.
