These days, Venetia would have been going for six-monthly ‘vampire facials’ with Dr Daniel Sister. In 2008, Sister was the first surgeon in this country to offer the £600 PRP (platelet-rich plasma) treatment, also known as ‘Dracula therapy’ because it involves giving a small vial of blood, which is then put into a machine and separated, using centrifugal force, into two components — red blood cells (which are discarded, or, if you are Kim Kardashian, smeared over the face and shown off in a selfie — see previous page) and plasma, which is full of human growth factors (ie, the platelets) and, if injected back into specific parts of the body, helps them heal. This fact was discovered in the 1950s by two scientists, who won the Nobel prize for their work, and it was applied to sports injuries (Tiger Woods had it in his knee), dental implants and military casualties before being taken up for cosmetic use. ‘I inject the plasma on three different levels: deeply around the eyes and in the jawline,’ Dr Sister told me, ‘then medium-deep on the cheeks, and lightly scattered across the rest of the face. This has the best results.’
