About GEM©
GEM© by Harley Academy is the Global Evidence Matrix - a groundbreaking innovation in patient and practitioner safety
GEM© is a set of principles developed by our Founder & CEO, Dr Tristan Mehta, following research led by our Director of Education, the esteemed anatomist and researcher, Professor Sebastian Cotofana
These standardise the administration of cosmetic injectables, evidenced by regularly updated clinical safety data. GEM© provides - for the first time - all the details clinicians require to complete aesthetic treatments in the safest possible way, based on their skill level

What users are saying about GEM©
"I've just completed my first bit of eLearning and am going on the Foundation course next month. I hadn't looked at GEM because I was focused on my Foundation eLearning but now I wish I'd looked at this platform sooner! It's amazing, thank you and I feel more confident going forward now I've seen what I can learn through GEM"
Dr Elinor James, Aesthetic Doctor & Level 7 trainee, March 2025
"It's already an incredibly useful and streamlined learning resource that does not exist anywhere else that I've seen. If I want to look closely at techniques, I have to trawl through journal articles. This condenses the research and teaching that isn't actually made available altogether anywhere else that I've seen"
Natalie Billington, Cosmetic Nurse & Level 7 trainee, February 2025
