"When it comes to make-up, you have a lot more freedom when you haven't got any lines on your face," says Lisa. "You rarely look tired in your teens and 20s, so you get away with a lot more." These low-maintenance days are the best time to experiment with bold colours and make-up trends.
But it's not too early to start thinking about caring for your skin. "I started using eye cream at 23 and I'm religious about it," Lisa explains. "It's very thin skin and a very expressive area of the face, so it's the first place you're going to show signs of ageing. I don't mind having a few lines around my eyes, but why not protect it? It's so easy to do."
"I've got a few eye creams that I like but the one I personally use is by SK-II," she adds. "It's very expensive but it lasts so much longer than everything else."
Your 20s are a good time to prepare for your skin care future too. "I don't believe people have to look young, I just believe you should look your best," says Lisa. "Achieving that when you're older is about looking after yourself from an early age. If you start to use eye creams, hand creams and sun creams in your 20s, that's a preventative measure - a caring, nurturing thing to do for yourself that will help you look good as you get older."
