How to keep your skin looking younger for longer?

What we do makes a real difference and we can all have some control over how well our faces age by following some basic guidelines.

• PREVENTION. What you do in your twenties really affects how well you age in your forties and fifties. Make sure any habits you develop are good ones. But it's never too late to start looking after your skin with a sensible moisturizing, nurturing skincare regime.

• WEAR SUNGLASSES. Wearing sunglasses with UV protective lenses can avoid developing crow's feet from squinting in the sun. They will also guard against long-term damage long-term damage to your eyes.

• AVOID SUN EXPOSURE.  Avoid overexposure to the sun and always wear sunscreen rated SPF15 or higher that protects against UVA and UVB. Remember that much of the harm happens by chance whenever we're outside and that tanning is a sign of sun damage. Don't forget your neck, décolletage and the back of your hands. Nothing ages faster than sun exposure, except smoking. Sun damage accounts for up to 90% of wrinkles and other signs of premature ageing.

• GIVE UP SMOKING. It's not always easy but this is the one choice you can make that will really affect how old you look. It's estimated that an average smoker ages 14 years for every 10 years of smoking. Do it for your skin, and your health in general.

• SLEEP ON YOUR BACK. If you always sleep on the same side, the pillow puts pressure on your face leading to lines over the years; lying on your back encourages blood flow and reduces puffiness. Silk pillowcases can also help.

• AVOID YO-YO DIETS. Constantly losing and gaining weight damages skin. If you need to diet, aim for gradual, sustainable weight loss.

• IMPROVE YOUR DIET. Balanced nutrition including plenty of fruit and vegetables is essential for healthy skin. B vitamins biotin and niacinamide (B3) are particularly good for the skin, while vitamins C and E are antioxidant, helping to fight free radicals and protect from sun damage. Vitamin C is also essential for collagen production while Vitamin A helps to repair and maintain skin tissue.

• DRINK PLENTY OF WATER. Drinking plenty of water keeps skin hydrated and plump out fine lines. This is such a simple tip, but it really makes a visible difference to your skin.

• EXERCISE. It goes without saying that exercise, fresh air and a good night's sleep all work wonders for your looks.
