Quick Overview
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 foundation in General Medicine within the NHS underpins a rigorous, ethical, and evidence-based approach to advanced skin rejuvenation.
With specialist training in both the UK and internationally - including South Korea’s renowned Gangnam district and the Middle East - Dr Dianni has developed a deep understanding of skin biology, ageing pathways, and ethnic skin variation. This enables her to deliver highly personalised treatments focused on restoring skin function, resilience, and long-term quality.
Dr Dianni is highly experienced in advanced regenerative skin treatments, including Profhilo, PRP (platelet-rich plasma), and exosome therapy, selecting and combining these modalities based on each patient’s skin condition and biological needs. Her approach prioritises cellular repair and collagen stimulation rather than surface-level correction. Treatments such as Profhilo are used to improve hydration and elasticity, while PRP and exosomes support tissue regeneration, skin repair, and recovery at a cellular level. This integrated strategy is particularly effective for addressing skin laxity, fine lines, dullness, inflammation, and post-procedure healing.
As the founder and medical director of Dr L’Art in London, Dr Dianni oversees all regenerative skin treatments with the same clinical integrity developed through years of medical practice. Her philosophy centres on strengthening the skin from within - helping patients achieve healthier, more youthful skin through scientifically guided, bespoke care.
