Strengthen and Define

At Dr Kathryn Aesthetics & Skincare in Cardiff, we offer treatment for both men and women looking to shape and augment their jawline, known as jawline fillers. While men often want to achieve firmer, more defined lines, women often wish to achieve a more delicate but equally defined jawline, as part of the ‘heart-shaped face’ aesthetic, though of course, this varies from person to person. Dermal fillers can be placed and integrated with your facial tissue to achieve your aesthetic goals, delivering natural-looking results.

“Excellent service so pleased with the natural look I’m being given and it’s making me feel far more confident. Dr Kathryn is simply the best!”

With her many years of experience as a doctor, Dr Kathryn combines the highest professional standards with a passion for skin care and aesthetics.

Treatment journey

Your treatment journey



Consultation is the first step in any treatment journey. Taking your medical history into account, we will listen carefully to understand your concerns and agree on a personalised treatment plan to help you reach your aesthetic goals.



From anti-wrinkle injections to chemical peels to dermal fillers, Dr Kathryn will draw from her knowledge and experience to expertly deliver the treatments agreed during your consultation, making sure you are comfortable and at ease.



Though many treatments can be slotted into a short break in your working day, some require downtime and aftercare. We will advise you of anything you should avoid, while making sure you know the best way to care for your skin after your jawline fillers.


Questions about your treatment

  • Even those nature has blessed with a naturally clear, well-defined jawline can lose it as they age. In youth, fat pads in the cheeks are saturated and supported, held up by supple, firm skin, but as the skin loses its elasticity, that facial volume sinks down the face and gathers around the jaw, obscuring the clear lines of youth.

  • Dermal fillers have a gel-like consistency so they can be injected and gently massaged into place, creating shape and volume where it is needed. Our expert clinicians know exactly how to assess the shape of your jaw and apply the fillers in the best way to achieve your aesthetic goals.

  • Dermal fillers largely consist of hyaluronic acid, a naturally occurring substance in the body that binds water within the skin, supplying abundant hydration and integrating with your facial tissues. Dermal fillers also contain a small amount of local anaesthetic to minimise any discomfort associated with needles.

  • One of the benefits of dermal filler is that its gel-like consistency is of just the right viscosity to be massaged into place, where it readily integrates with your natural tissue. At Dr Kathryn Aesthetics & Skincare, we only use high quality, reputable dermal fillers that deliver results. Though it remains possible for some of the filler to ‘migrate’, that rare circumstance is something we can also correct with a follow-up treatment.

  • One of the most celebrated features of dermal fillers is that results are visible immediately. There might be some slight bruising, swelling, or redness at the injection sites but these will fade within a few days. Results can last anywhere from 6-18 months, depending on the client, their skin, and their lifestyle.

“DR Kathryn is incredibly professional, welcoming and knowledgeable I wouldn’t trust anyone to do my treatments. Always get amazing results.”
