Jawline Slimming

Jawline slimming is a non-surgical cosmetic treatment designed to create a more contoured, V-shaped facial appearance. It targets the masseter muscles — the large muscles on either side of the jaw — which can appear enlarged due to genetics or teeth grinding (bruxism).

Dr Dianni Dai, Medical Director

Dr Dianni is a medically qualified aesthetic doctor with dual degrees in medicine, including a Master’s degree in Aesthetic Medicine, and over 11 years of clinical experience. Her background in General Medicine within the NHS underpins a meticulous, ethical, and evidence-based approach to facial aesthetics.

With advanced aesthetic training in both the UK and internationally - including specialist education in South Korea’s renowned Gangnam district and the Middle East - Dr Dianni has developed a deep understanding of facial anatomy, muscular dynamics, and ethnic variation. This enables her to sculpt the face with precision, balance, and cultural sensitivity, enhancing features while preserving individuality.

Dr Dianni is a recognised expert in facial sculpting and contouring, specialising in masseter reduction for face slimming, jawline and chin enhancement, platysma neck lift techniques, and advanced dermal filler treatments. Her approach views the face as a dynamic structure rather than isolated features, combining muscle modulation, structural support, and volume optimisation to create refined proportions and natural harmony. By strategically integrating these techniques, she addresses facial width, lower-face heaviness, jaw definition, and neck tension in a cohesive and medically informed way.

As the founder and medical director of Dr L’Art in London, Dr Dianni oversees all injectable treatments with the same clinical integrity developed through years of medical practice. She is a registered member of the British College of Aesthetic Medicine and the British Medical Laser Association, a Key Opinion Leader for Dibi Milano, an Ultherapy expert, and an official UK partner for Juvelook , Ellansé and Rejuran Polynucleotides.
