Meet Jen Barclay

Registered Nurse ·

Independent Nurse Prescriber ·

Founder of The Rejuvenation Rooms

With over 16 years of experience in medical aesthetics, Jen Barclay brings together advanced clinical expertise and an artist’s eye for detail.

Her career began within Reconstructive Plastic Surgery in the NHS, where she developed a deep respect for precision and patient care - foundations that continue to guide her work today.

Since moving into aesthetic medicine in 2010, Jen has trained extensively alongside leading specialists and served as Lead Nurse within some of the UK’s most highly regarded clinics. This depth of experience inspired her to establish The Rejuvenation Rooms in Windsor, a private space designed to deliver the highest standards of safety, subtlety, and personalised care.

Jen is registered with the Nursing and Midwifery Council (NMC) and is a proud member of:

  • British Association of Medical Aesthetic Nurses (BAMAN)

  • The Aesthetics Complications Expert Group (ACE)

  • The Joint Council for Cosmetic Practitioners (JCCP)

Each of these organisations champions clinical excellence, accountability, and patient safety — values at the heart of Jen’s practice.

Continuing her professional development, Jen is currently completing her Level 7 Diploma in Botox & Dermal Fillers with Harley Academy, the UK’s most advanced postgraduate qualification in aesthetics.

In 2024, Jen was honoured to be included by Alice Hart-Davis and The Tweakments Guide in their Recommended List of Aesthetic Practitioners — a carefully curated guide to the UK’s most trusted and skilled clinicians.

  • "I can't recommend Jen highly enough! She is incredibly skilled, personable, and makes you feel completely at ease from the moment you walk in. The results are always natural and beautifully tailored to your needs. She truly prioritises what's best for you rather than pushing unnecessary treatments, which is so refreshing."

  • Jenna is patient, kind and is a total perfectionist! She takes the time to really listen to you about the look you want to achieve and I have never been disappointed. Going to see jenna is like seeing an old friend, you are put at ease instantly and her workspace is spotlessly clean and inviting. I wouldn't go anywhere else

  • Firstly Jen is just lovely so warm and welcoming and makes you feel at ease. Her knowledge is first class she really knows her industry. She's medically trained which for me is so important when looking for an aesthetics practitioner. Due to her years of experience my treatment looks natural and the placement is perfect.
