I have a problem. I shine – sadly, not like Lea Michele blasting out another catchy tune in the hit series Glee, more like a particularly effective furniture polish. As I also have a rather round, pale face, when my skin gets shiny, I look like a big greasy satellite dish, glinting in the sun. If I stuck my finger in a plug, I could probably pick up some Italian TV channels. You can imagine how hilarious I find this.

One thing I’ve learned over the years is constantly applying extra powder doesn’t work. Cake face? You end up looking like the love-child of Mr Kipling and Sara Lee. There is a solution, though, that I learned from a facialist at the Tshuggen Bergoase Spa in Switzerland, above. It’s to apply the very appropriately named Dr Feelgood by Benefit (£21.50), left. It’s a light balm that’s sold as a primer but works even better as an alternative to powder to mattify your make-up without flattening out your features. I use powder first thing, then when I need to retouch, I gently pat on some Dr Feelgood. It leaves a soft sheen that could easily be mistaken for a natural-looking glowing skin – even by those not wearing beer goggles. And. according to the advertising blurb, it also contains Vitamin A, C and E “to help smooth away the appearance of fine lines”. Now if they could just find a weight-loss angle for it, their work would be done.
