Beauty kit: Kate Moss on her travels

What's your favourite beauty treatment?

'I recently had my eyelashes done for the first time. I went to the same woman who sees Naomi Campbell - she applies each lash individually. It was supposed to take an hour and a half, but it took five hours for me because I couldn't stop talking.'

Where do you go to relax?

'St Tropez. I once went for six weeks and it felt as if I lived there. It wasn't like a two-week holiday, because I really got to know all the bars and restaurants, all the beaches and the people, and where to get the boats too. It's a real home-away-from-home, and it's wonderful for families - my daughter absolutely loves it. We take all of her friends, avoid places like Nikki Beach, and just relax.'

How do you look after your skin on long-haul journeys?

'I use Crème de la Mer - it's a tried and tested brand for me. I usually like experimenting with different products, but this is the most enriching I've found. During the day I apply the Moisturizing Soft Cream, but at night use the original Moisturizing Cream. The St. Tropez Luxe Facial Oil is nice too; it feels really soft on your skin, like you're plumping it up and putting a bit of life back into it.'

Do you like to sunbathe?

'I have a typically English complexion, but although my skin tone is fair I go quite golden in the sun. When I was younger, I wasn't very careful about looking after my skin. I'm better now, although last summer I was on holiday in Ibiza and wanted to tan my bum, so I used oil. And, of course, I burnt it.'

What is your number one beauty travel tip?

'I always try to sleep on the plane and then stay up when I arrive at my destination, so I get used to my new time zone straight away.'

How do you prepare your skin before a holiday?

'The first thing I do in the morning is put on St. Tropez Gradual Tan In Shower. You can use it every day, because the colour builds. It's not a drastic change, but it just gives you a subtle hint of colour and that healthy glow.'

What sun cream would you recommend?

'I love La Roche-Posay Anthelios SPF30 Smooth Lotion - it's great as it contains antioxidants. They also do an ultra-light SPF50+ fluid for the face, which is amazing. It's not sticky at all.'

What's your beauty crime?

'Not taking off my make-up before I go to bed, although I do try. I keep my routine quite simple, so there's little room for mistakes, thankfully.'

What fragrance do you wear in the summer?

'When I'm on holiday, I like to give myself a spritz of Clarins Eau Dynamisante before lunch. It's so fresh.'

Do you change your make-up when you're on holiday?

'When I'm tanned, I love wearing the Golden Goddess range by Charlotte Tilbury. The Beach Stick is great instead of bronzer - that's literally all I used when I was in Ibiza.'
