Weak Chin: Causes, Symptoms and Treatment

What is a weak chin?

A ‘weak’ or recessive chin is a term used to describe a jawline that lacks definition and shape when viewed in profile. The official medical term for a weak chin is ‘retrogenia.’

What causes a weak chin?

A weak chin is usually the result of genetics and is not a sign there is anything medically wrong. In some rare cases, a weak chin can be caused by a trauma to the face, but most often it’s simply a result of where your mandible (lower jaw) naturally sits in relation to your upper jaw.

How can I improve a weak chin?

There are cosmetic treatments available that are designed to make a weak chin look more defined. These include:

  • Dermal fillers: This treatment involves injecting a liquid containing hyaluronic acid under the surface of the skin to add volume to the chin and jawline. It’s a non-permanent, non-surgical procedure and the results can last from six months to two years.
  • Chin implant: An implant made out of silicone, Teflon™, dacron, or a biological implant made from cartilage and bone, can be inserted under the skin through a surgical procedure. This creates the effect of a more prominent jaw bone and can offer permanent results.
  • Dentistry: A dentist may be able to improve the appearance of a weak chin with surgical and non-surgical dental procedures. These include braces to help address an overbite (which can make a weak chin more noticeable) and surgery on the jaw.


Can exercises improve a weak chin?

There are lots of exercises online purporting to strengthen or add definition to a weak or recessive chin. Unfortunately, there is no evidence to suggest these exercises have any visible impact on the appearance or size of your chin.

Is a weak chin genetic?

Yes, a weak chin is usually passed down genetically and is not generally caused by other factors.

Will losing weight improve the appearance of a weak chin?

If you’re overweight, losing a few pounds could help your jawline appear more defined. However, it’s important to remember that a weak chin is genetic and so losing weight may not have any effect on the prominence of your chin.

How long do chin fillers last?

Depending on the type of fillers used and the extent of the treatment, chin fillers can last between six months and two years.

Can men and women have chin fillers?

Yes. Chin fillers can be used to enhance the shape and size of the chin for both men and women.

I’m transgender. Can chin fillers make me look more feminine/masculine?

Subtle differences in the shape and contours of the face can make someone appear more masculine or feminine. Dermal fillers can be used to shape and sculpt the jawline, chin, cheekbones and lips to create a more masculine or feminine look.
