Dr Hilary has explained the correct way to wear a face mask to protect yourself during the coronavirus pandemic.
Speaking on Good Morning Britain on Friday, the TV doctor gave a step by step guide on how to put on a mask properly and in a hygienic way.
Face masks are now mandatory for people over the age of 11 in enclosed places such us on public transport and in shops, except for those who are medically exempt.
The first step in Dr Hilary's tutorial is to make sure your hands are sterilised with either hand sanitiser or soap and water.
He said: "There is no point putting on a mask on if your hands are already contaminated because you're contaminating your mask."
The mask should be put on your face using just the loops to attach it to yourself behind the ears.
It should cover both your nose and mouth.
Dr Hilary said: "I haven't touched the front of my mask because I don't want to contaminate it.
"I'm not going to drop my mask below the mouth at any time and I'm not going to put it under my chin to talk to people.
"The whole purpose of the mask is that you're stopping any droplets that emerge from your mouth when you're talking, sneezing, coughing, etc."
When you want to remove your mask you should again sanitise your hands and only touch the loops.
If it's disposable it should be chucked straight in the bin and if it's reusable wash it and use another while it's in the wash.
"That is how to properly wear a mask," Dr Hilary said at the end of the tutorial.
