First you must understand wrinkles Three layers make up skin. The surface, visible layer is called the Epidermis. Under the epidermis lies the middle layer known as the Dermis. Beneath this is the Subcutaneous layer, the third innermost layer. As we age the dermis or middle layer looses it's elastic quality. The dermis contains fibres called Elastin and a protein called Collagen, both of which prevent wrinkles and allow the skin to have that young, fresh look and feel.

The skin is able to retain moisture and the ability to stretch. As time goes by the dermis gradually loses both Elastin and Collagen, causing the skin to become thinner and less able to retain moisture. The subcutaneous layer also begins to lose the fat that gives youthful skin that pleasant smooth look.

Wrinkles around the eyes, known as crows feet, and the brow also become visible due to the contraction of minute muscles just beneath the skin surrounding the area.

Age is not alone in causing crows feet and furrowed brows, squinting in poor light or strong sunlight or even uncorrected vision impairment can hasten the wrinkling process.

The skins natural oil is called Sebum, and some people will have more and others less sebum and/or collagen, the elastin quality will also vary from person to person so wrinkles can appear at an early age on the unfortunate or be delayed well into middle age.

Its all down to genes and lifestyle. My tips to slow down the onset of wrinkles. The first sign of wrinkling is around the eyes. You may look and feel great when you get a sun tan but nothing hastens the appearance of wrinkles than exposure to strong sunlight.

You may look wonderfully glamorous with that all over tan but, in time, you will more than likely look prematurely old as your skin withers and creases start to appear around your eyes and on your forehead.

Remember that when you first see somebody you both will look into each others eyes so it is important to keep them looking fresh and youthful for as long as possible.

So do not be tempted by the sun. Always use a high factor good quality sunblock, at least 20 SPF (Sun Protection Factor) or above (I always use 30 SPF even in late afternoon sun), and re-apply every 2-3 hours.

Sunglasses with high quality UV (Ultra Violet) reflecting lenses are an absolute essential and should be worn outside during daylight hours even when grey and murky. Guess what - UV rays can still get through on a dull day.

My personal preference is for Polaroid lenses with a coating on the rear to cut down on reflected glare although other types of UV filtering lenses are just as able to do a good job. Fortunately there is a huge choice of glamorous good quality designer shades to choose from.

Also bear in mind no sunblock or sunglass lens will block out all harmful UV rays and be particularly aware of the harm sunlight can do when reflecting off snow or water.

Lots of models smoke as this is a very stressful occupation. Models often have to attend several castings a day and each time put up with critical comments on their looks and their suitability for the job.

Living up to expectations when posing in front of the camera or walking the catwalk after hectic costume changes puts a strain on the nerves and a timely cigarette helps to relieve the tension.

However we are all aware that smoking hastens the onset of wrinkles and aging and can shorten our careers. One of the principal effects is that smoking deprives the skin of precious moisture and so hastens the drying out process.

Avoid smoky and badly ventilated atmospheres that can also have the same effect.

Don't spend too much time in front of a computer screen as this can cause eye strain and squinting.

Get an anti-glare filter and remember to keep looking away at least every 15 minutes and focus on another object.

Do not be tempted to go to a tanning booth. Although eye protection is provided, the exposure to artificial UV rays can hasten the onset of wrinkling as much as natural sunlight and there is an argument that the damage can be worse.

Drink plenty of water. I always carry a bottle of water wherever I go and I know most models do the same. Before going out in the evening I drink a pint of cool water so if I drink some wine it cuts down on that dehydrating effect that alcohol can have ' and helps to keep you sober.

Use a light moisturizer on your face every morning and every night without fail. Pay particular care around the eyes and to avoid stretching the skin use a gentle circular motion with your finger tips.

One tip my Mother taught me. Avoid resting your head on your hands as the upward pressure creases the skin particularly around the outside corner of the eye.

Professional modeling is just the same as any other career, to be successful you have to work at it. Eventually a models' looks will go, some will have only a short career others may go on for a lot longer before the inevitable happens.

Nine times out of ten the first sign is wrinkling around the eyes and the camera always notices it. The appearance of crows feet signals the onset of aging for all women so it is of the utmost importance to keep the eyes looking young and vital if you value your looks and want to create that great first impression when you meet someone new.

Eye Contact Is First Contact
