ISABELLA ROSSELLINI ON WHY SHE’LL BE CO-STARRING WITH HER DOG DURING BELFAST SHOW

Isabella’s approach to ageing is to simply “embrace it”, while taking care of her skin and enhancing her best features.

Every morning, she applies an eye cream and face cream before sunscreen.

“In the winter, when it looks grey, I tend to forget the SPF, but by this season I became very religious about putting on my sun protection,” she said. “I use Lancome Multi-Glow, to try to be sophisticated and elegant throughout my life.”

She believes positive thinking is very important to looking good.

“I’m lucky that I was born joyful, whereas my twin sister is very shy. But when I look at myself in the mirror, I do see my neck — it drives me crazy!

“It’s not that I’m immune to that voice. But I try not to listen and to say, ‘Hey, but the lipstick still looks pretty good!’” She keeps her fine hair — “my weak point” — short and emphasises her full lips. She experiments with different shades of lipstick, using brighter reds in the summer and reds with darker tones in the winter. She prefers matte lipsticks, as opposed to gloss. “If you put on lipstick, exercise, eat healthy, dress nice, and clean your house, you become happier and things look better.” Isabella uses a lip liner that is a shade or two darker than her lipstick, citing Lie de Vin by Lancome, as one of her favourites.

“I apply straight from the tube, blot with tissue, then swipe it on again.”
