According to dermatology experts, if you're worried about wrinkles you need to get serious about skincare, use the right creams for you and, crucially, give them time to work. A slapdash approach means you're wasting you're time. Lines and wrinkles can only be lessened by consciencious care and daily ritual. Another classic mistake is slathering skin care products on thickly. Don't over do it.
A pea-size blob of cream may be enough for your face without clogging pores. Be prepared to experiment with new formulas as your skin changes.
What makes the skin wrinkle?
Our skin is devided into three layers. The deepest is a layer of subcutaneous tissue, to which the whole skin structure is attached. The middle layer is the dermis, where cells called fibroblasts produce collagen fibres - supporting proteins that help to keep skin plump and elastic. Above this lies the top layer, or epidermis. Here, mast cells divide gradually and migrate upwards towards the skin's surface. These are surrounded by natural compounds called epidermal lipids (or fats), including ceramide, which forms a 'glue' that hold cells tightly in place, like cement in brick wall.
The collagen bundles in the dermis work like springs in a mattress to support the skin's surface. But when collagen is damaged , troughs open up between the bundles, the upper layers of tissue collapse into these troughs, and lines, wrinkles or folds can develop. By the time you see a wrinkle, underlying skin has already lost collagen and elastin - its 'snap-back' factor. Collagen is damaged, by various factors. Some are inevitable (such as ageing), and some can be lessened, if not prevented.
What are the main culprits, and what can you do about it?
CAUSE: The enviroment
EFFECT:Brow and eye creases, fine lines fanning over cheekbones, rings and criss-crosses at the back of the neck
New research by The British Skin Fundation found that 80 per cent of us don't always use a sunscreen abroad, let alone on a sunny day in UK. Sun damages DNA so cells can't replicate properly. If that cell blueprint is changed in any way, it can lead to blotchy skin, lines and wrinkles. At the same time, UV boosts enzymes known as MMPs, which help to tidy up old collagen, but can become so agreessive that they destroy fresh collagen, too.
Smoking in the sun is especially bad news. Even second-hand smoke is harmful to skin. Exhaled smoke contains significant levels of nicotine, tar, nitric oxide and carbon monoxide, which disrupt and weaken the skin's barrier, leading to collagen breakdown. Smoking causes blood vessels to constrict, which limits the amount of oxygen reaching the skin. This lack of oxygen reduces collagen and elastin production. Smoking stimulates the MMPs to degrade collagen - just like the sun does.
CAUSE: Facial expressions, stress
EFFECT: Frown lines, crows feet, smile lines
Expression lines equal character. Even Hollywood directors have started to complain that Botox has robbed some star's faces of real emotion. While channelling the angst may help divas to win an Oscar, it doesn't do their skin any real-life favours. Stress triggers corrosive hormones including 'killer' cortisols that not only hamper immunity, but also increase moisture loss, leaving skin drier and more line-prone. Clenched muscles in the neck, shoulders and jaw - where so many of us hold our stress- limits blood and oxygen supply to the skin on our faces. But a furrowed brow is the most obvious sign of stress. Constantly pleating the skin through frowning causes micro-tears (minute stress tears). The knock-on effect is inflammation, which damages collagen, making skin appear less plump.
Not only expression lines are stress-driven, however. Where skin is constantly mobile - such as round the eyes and mouth - creases are inevitable. So what about damage limitation? Invest in sunglasses. Wrap-around frames with wide sides provide excellent UV protection, and can save a fortune in Botox!
CAUSE: Ageing
EFFECT: Crepey skin, deeper eye creases, nose-to-mouth lines, marionette (mouth to chin) lines,lip lines, neck rings
Great skin is in your genes but even if you are one of the lucky ones, don't take it for granted. After all, hereditary ageing may only account for 20 per cent of total skin ageing. This intensifies from our mid-thirties, when protein levels in our skin begin to decline by a steady one per cent each year. Later, the oestrogen slump after the menopause more than doubles the rate at which protein declines - we lose a staggering 30 per cent of collagen proteins in the first five years, resulting in a two per cent loss of skin thickness.
As well losing collagen, skin also loses plumpness because cell division slows with age. This is because stem cells are no longer able to divide and replicate accurately, and become dormant. New research shows that one of the latest hi-tech ingredients in skin creams - poly-peptides - mimic growth factors in skin to wake up dormant stem cells and encourage fibroblasts to make more collagen. Although results look promising in the test tube, the use of growth factor peptides in anti-ageing creams remains controversial.
In the meantime, retinoid-derived from vitamin A is still the only ingredient clinically proven to boost both collagen and moisturising hyaluronic acid. This was confirmed by research at the University of Michigan Medical School earlier this year. Some peptides can help smooth fine surface lines within a couple of weeks. But you need retinoids for long-term cell growth and real anti-ageing benefits. Like vitamin C, you also need to use them round the clock for up to two months before you see results, but it's worth the wait.
