WHY JUVENOLOGY EXISTS
Appearance, health and wellbeing deserve to be considered together.
I founded Juvenology because I believe ageing well means understanding our bodies as well as caring for how we look and feel.
I wanted a clinic where people have time to talk, where concerns are carefully assessed, and where recommendations reflect each person’s needs, lifestyle and goals.

MEET MARINA
From cardiac nursing to aesthetics and longevity
I qualified as a nurse in Bulgaria in 1999 and spent more than a decade in cardiac nursing in Sofia. In the UK, I worked in cardiac care at William Harvey Hospital, Spencer Private Hospital and KIMS Hospital, then as an aesthetic nurse specialist at Spencer Private Hospitals.
My experience in cardiovascular assessment, diagnostics and rehabilitation still shapes how I work today. I listen carefully, consider your wider health and treat each person as an individual.
1999
Graduated in nursing in Bulgaria, then worked in cardiac nursing in Sofia from 2000.
2011
Moved to UK cardiac nursing at William Harvey, Spencer Private and KIMS hospitals.
2016
Founded Juvenology in Maidstone, Kent.
2025–26
Further training in healthy longevity (NUS), longevity medicine (GCLS) and HeartMath®.

HOW I WORK
Careful assessment and honest advice
01
Listen
We start with your concerns, goals and lifestyle. You don’t need to choose a treatment before we meet.
02
Assess
I review your medical history and medications, and assess your skin and facial anatomy.
03
Explain
We talk through suitable options, what they may and may not achieve, potential risks and aftercare.
04
Decide
If I don’t believe a treatment is right for you, I’ll say so. There is no obligation to go ahead.
WHO CARRIES OUT YOUR TREATMENT?
I personally carry out consultations and injectable treatments, including dermal fillers, Profhilo and polynucleotides, as well as microneedling and exosome treatments. You will know who is responsible for your care before you decide whether to go ahead.
