Model behaviour

Model, entrepreneur, and radio and TV personality Lisa S (born Lisa Selesner) may be known for her flawless looks, but the Monaco-born beauty wasn't always curious about cosmetics.

"I only became interested when I started modelling when I was 14. Before that, I only cared about my passion of riding horses, and in that sport you don't wear make-up because you sweat a lot. Now it's an obsession," says the founder of Glamabox, which delivers cosmetics samples through a monthly subscription.

These days, Selesner sticks to a few simple beauty rules. "I always, always wash my face at the end of the day and I always put on SPF," she says.

"Right now, I'm really loving La Roche-Posay day cream because it's great for sensitive or allergic skin. It's preservative-free, fragrance-free, alcohol-free, colourant-free and lanolin-free."
