Your skin is a mirror. How it ages is a complex process involving a number of factors. Some of these, such as genes, gravity and normal ageing, are not within your control, but many others are.Prematurely ageing skin often mirrors the body’s inefficiency in eliminating toxins and waste products. Excess sun exposure creates skin-damaging free radicals, leading to `photoageing’ UV (ultraviolet) A is especially harmful as it breaks down skin collagen fibres (J Invest Dermatol, 2001; 117: 1218-24). However, sun and pollution are more potent than sun exposure alone, and cigarettes are more damaging than either.

Smoking ages skin by destroying collagen and reducing circulation, thus reducing oxygen and essential nutrients to the skin. Smoking 20 cigarettes a day for just a few years is equivalent to nearly 10 years of chronological ageing (Br J Dermatol, 2002;147:1187-91) -a much greater rate of damage than lifelong sun exposure.

Wrinkle-causing cream?

Many intelligent individuals scan food labels for harmful additives, yet will use toiletries containing a multitude of undesirable chemicals. But facial skin is thinner than skin elsewhere, and may thus absorb toxic chemicals (such as petroleum byproducts, carcinogens, solvents, oestrogenic suncreams and preservatives) more readily.

In addition, many anti-wrinkle creams use harsh chemicals like alpha-hydroxy acids, glycolic or lactic acid, passionflower or citrus extract to strip away superficial skin. Recent evidence suggests that these agents actually cause premature ageing as well as increase W susceptibility (Arch Dermatol, 1996; 132: 631-6; J Am Acad Dermato1,1996; 34:187-95).

Natural alternatives

In today’s creams, semi-synthetic lipids (fats, oils) and their constituents, including ceramide, hyaluronic acid, cholesterol, triglycerides, phospholipids and glycerine, have mostly replaced mineral oils (paraffinum liquidum, petrolatum). Many also use silicones (dimethicone and various siloxanes), which produce water-repellent `dry’ oils and waxes. While they increase the `feel-good factor’ of a product, they are poorly absorbed by the skin. This places a question mark over how well ingredients suspended in them will be absorbed. Some, like dimethicone, are also cancer-causing suspects.

Natural vegetable oils (almond, jojoba, coconut, Soya, carrot, wheatgerm, macadamia, olive and avocado) and some animal-derived oils (squalene and emu) are well absorbed and more compatible with human skin. High in essential fatty acids and vitamins A, D and E, these fatty acids temporarily strengthen cell membranes, slow down the formation of fine lines and wrinkles, and resist free-radical damage.Beeswax and Soya wax are good alternatives to silicones, while vegetable glycerine and honey are good replacements for synthetic humectants (water-attracting substances) like propylene glycol.

Antioxidants may also help. Coenzyme Q10 (ubiquinone) can smooth wrinkles, though published human research is scant. Vitamin E (as alpha-tocopherol or tocotrienol) is antioxidant and helps prolong the product’s shelf life. Some studies suggest it can also smooth superficial wrinkles, if used continuously.Alpha-lipoic acid (ALA) scavenges free radicals, is rapidly available to skin cells and may be LJV protective.

Vitamins C and E work well in combination against UVB. Vitamin E also can work in synergy with carotenoids. Other UV-protective nutrients include selenium, Ginkgo biloba extract and aloe vera. Many plant extracts, such as rosehip oil and horsetail, as well as those from cocoa and green tea are also antioxidant.

Skin food: what prevents and what promotes wrinkles

Diet can significantly affect the skin and its tendency to wrinkle. Researchers from Monash University studied the diets of 453 people (aged 70 years and over, from Australia, Greece and Sweden) to see if foods are associated with skin wrinkling. The findings strongly suggest that a high intake of fruits, vegetables and fish as well as certain healthy fats can protect against wrinkles (Am Coll Nutr, 2001; 20: 71-80).

Foods that protect against wrinkles

Higher total fats, monounsaturated fats

Whole-grain cereals, eggs, water, tea

Olive oil and olives

Zinc-containing foods (seafood, lean meat, milk and nuts)

Fish (especially fatty fish)

Reduced-fat milk and-milk products

Nuts and legumes (especially lima and broad beans)

Vegetables (especially leafy greens spinach, eggplant, asparagus, celery, onion, leek and garlic)

Fruit and fruit products (especially prunes, cherries, apples and jams)

Foods that promote wrinkles

Saturated fats Meat (especially fatty processed meats)

Full-fat dairy products (especially unfermented products and ice cream)

Soft drinks and cordials cakes, pastries and desserts potatoes

Butter

Margarine

Vitamin C supplements
