When do ‘preventative’ injections cross the line and start making you look older? Can wearing a bra to bed really prevent sagging? And do you need to see a gynaecologist if you've never had sex? In this episode, we speak to Consultant Dermatologist and Specialist Cosmetic Injector, Dr Cara McDonald to get the truth about anti-ageing, skincare ingredients and cosmetic procedures. She gives her expert rating (out of 10) for the most popular skincare ingredients - from your hyaluronic acids to your retinoids - and if they’re really that great in the fight against ageing. We cover everything from why the operator is more important than the device, the dangers of over-filling and when removing all movement from your face can actually backfire... Dr Mariam breaks down the serious risks of ‘cosmetic tourism’, the differences between a ‘Plastic Surgeon’ and ‘cosmetic surgeon’ and how to identify a properly credentialed practitioner. Plus, we settle the "to bra in bed or not to bra in bed" debate, and whether it has any proven impact on sagging. And, in our quick consult, Dr Mariam answers a listener’s question about whether you still need to see that doctor if you've never done the deed.
