Owner & Director
Aesthetic Nurse

With over 38 years of experience as a Registered General Nurse and over 12 years as a Nurse Prescriber, Emma Southwick brings a wealth of clinical expertise and passion to the world of aesthetics. After spending the final 16 years of her NHS career in general practice, she gradually transitioned into full-time aesthetics in 2014, having started her aesthetics journey in 2010.

She is the founder of GSN Aesthetics, established in 2013, where she has built a reputation for delivering natural-looking results with a strong emphasis on skin health, quality, and patient wellbeing. Holding a Level 7 qualification in Aesthetics, she is deeply committed to continuing education and constantly evolving her practice — in her own words, “I’m never good enough!”, which perfectly reflects her drive to keep learning and improving.

Emma uses only clinically proven techniques and products, and focus will always be on patient safety and achieving as natural a look as possible. She carries out a medical assessment and an examination on all patients prior to their treatment journey and will be honest when advising you on the treatment/s that would meet your realistic needs and your budget.

Emma is also a big advocate of medical/pharmaceutical skin care and really believes on working on that “canvas” before painting a picture!

As a bowel cancer survivor, she is passionate about overall health, lifestyle, and wellbeing, encouraging her patients to take a holistic approach to aesthetics and self-care. She has a particular interest in the future of personalised and biologically-guided aesthetics, especially the growing role of diagnostics in treatment planning.
