Dr Tristan on Key Skills for Aesthetics Practitioners

Dr Tristan on Key Skills for Aesthetics Practitioners | Harley Academy

What are the key skills for aesthetics practitioners? Sure there’s the foundational knowledge relating to anatomical knowledge, safety and injecting skills. But what are the skills that make a technician into a specialist?

We asked Dr Tristan Mehta, creator of the Level 7 in Injectables qualification and founder of Harley Academy, for his expert advice.

Here are four of the top skills he recommends all aesthetics practitioners develop...

“One of the things I’m fixated on in medical aesthetics is the actual skill you have holding a syringe with a needle or with a cannula,” says Dr Tristan.

“This is something that we don’t focus on and talk about enough. We can talk all we want about complications management and anatomy and different fillers. But ultimately, how good are you with your hands?”

“How good are you, and how precise, and how stable are you?”, he asks. “What do you know about how to inject to make things easier for you and more comfortable for your patient?”

Manual dexterity is something that can obviously be improved with regular practice. However, there are also various tasks, tools and hobbies that can help with this too.

Ways for aesthetics practitioners to improve manual dexterity:

  • Play a musical instrument
  • Knitting, sewing or crochet
  • Practice origami
  • Stretch your fingers using elastic bands or small resistance bands used in finger rehabilitation
  • Play with manual dexterity toys such as fidget spinners
  • Practice picking up small objects using tweezers
  • Build up hand strength by squeezing paper, clay or Play-Doh into a ball


“We often get questions about treating different patient types. Injecting men with ‘tough skin, for example,” notes Dr Tristan.

“Sometimes you’ll notice when you’re treating the cheeks, the tissues are very responsive. You get a beautiful result, it doesn’t bleed and the patient’s happy.”

“Sometimes you’re going to inject a patient and you’re not going to see a big result,” he cautions. “Maybe you’re going to find it tough to get through the tissues and the patient is very bruised by the end of it.”

“Your job as an injector is to accept that there’s going to be a huge variety of patient types,” he confirms.

Whilst training, try to make sure you see as many different patient types and as many different presentations as possible. The more hands-on aesthetic training you do under the guidance of a mentor, the better prepared you’ll be when you start practising on your own.

When considering all the different patient types, you need to be ready for anything.

“Your approach has to be so finessed that you’re always minimising the risk of variability,” advises Dr Tristan. “This applies whether you’re treating a patient who’s considered straightforward or one that’s more challenging.”

At Harley Academy, training in a working aesthetics clinic allows you to develop your approach under the expert supervision of our mentors. Each mentor is a specialist injector in their own right outside of their clinical training roles. As such, each will have their own unique insights and advice to pass on.

Every piece of information and guidance they impart can help you to shape your own, personal approach to aesthetics. So if you train with us, come to your mentoring sessions with an open mind, ready to soak this knowledge up like a sponge!


Whether it’s patient selection, product choice or injecting techniques, as a medical professional, you should really hone your intuition.

“You need to almost anticipate when someone isn’t going to be able to be as responsive for certain treatments,” says Dr Tristan.

“For example, if someone has quite elastotic skin and is perhaps in the later decades of life, the envelope around the face is a bit looser. That means you can inject three or four mls of filler and it still won’t create as much projection and change in the tissues as you’d have otherwise seen in someone who’s younger.

“Patient selection and understanding the difference between the different kinds of cases you’ll experience, will massively affect the kind of outcomes you can get.

“I think that you have to take it upon yourself as an injector to be able to understand those different varieties of cases. You also need to have the same principles for how we’re injecting, to be as effective as we can with the products and the needles that we have.

Having solid intuition can help you most when it comes to patient selection. It can be particularly useful when sounding the alarm for patients you perhaps shouldn’t be treating. Again, knowing when a patient is not suitable, is a crucial skill all aesthetics practitioners need to develop.
