Can filler give me a more defined jawline and a v shape chin?

Yes! Dermal filler injections are a great option to define your jawline and create contour. It can help create chin or deliver a V shape that you seem to be interested in. It is hard to say exactly which filler would be best for you without a picture. Be sure to schedule a consultation with an expert! 

Hi there!
Thank you for your query. Dermal filler can be a very effective way of adding definition to the jawline and can also be used to add volume to the chin-giving the illusion of a ‘V shape’. Botox for jaw slimming could also be another non-surgical option. It would be worth visiting an experienced practitioner to discuss your options.
Hope this helps!
Best Wishes,
Dr Rupert
