Anti-Aging Skin Care Products: The Evolution
Anti-Aging Skin Care Products: The Evolution
During the last 10 years more attention is paid to the anti aging skin care. Developments within this category were influenced by such factors as competition among the major brands, introduction of new technologies and new ingredients, as well as worldwide increase in demand for the so-called "rejuvenating cosmetics". People have no intentions of putting up with aging. Today they are turning to alternative therapies and anti aging products; however, they will not spend money on products which do not produce the wished results.
First anti aging skin care products appeared during the late 1980s. The first liposome ingredient delivery system was part of first generation anti aging skin care.
David Jago, an expert in the market analysis for MINTEL, evaluates the changes, which have taken place since then: "At present, the special properties, ingredients and benefits of the products are clearly shown on the label. In the late 1980s, it was only said that those products were firming, softening the skin, reducing lines etc., but their functional ingredients were usually not disclosed. Today's press often informs us of specific ingredients and their benefits, thus contributing to the consumers' education". As a result, there appeared a category of skin care products intended for specific age groups or needs. Usually, women aim at making their aging skin look younger, or their young skin - healthier.
In the beginning of 1990s, many anti aging skin care ingredients have been studied. The most important of those, Alpha Hydroxyl Acids (AHA), became the first ingredients to affect the aging skin. Sally Penford, of the International Dermal Institute, a postgraduate training school for therapists, comments: "It stimulated women to start considering cosmetic surgery, glycolic acid peels and laser skin treatments".
Another "great revolution" in anti aging skin care has been in the use of A, C and E vitamins, as well as group B vitamins and main fatty acids - they all have a special role of agents preventing premature aging. Of course they do not make miracles, but can support the good condition of the skin. As skin ages and is repeatedly exposed to harmful UV rays, the level of vitamin A, produced in the body, constantly decreases. The skin renewal processes slow down and the epidermal layer becomes progressively thinner. Some of the research of the ingredients, such as vitamin C, was held in 1990s. Further, scientists identified two key chemical "helpers" to assist in the delivery of vitamin C through the skin.
The formulations derived from it led to the development of anti aging skin care products, containing vitamin C and products, which contained a combination of vitamin C and pure Retinol (until recently, it has been extremely hard to combine both Retinol and vitamin C together in a stable formulation, as both ingredients are easily oxidized, when exposed to the air, and become inactive). In 1990s this type of skin care was already produced all over the world.
Further on, a great deal of interest in the anti-oxidants has been shown. A lot of studies have been done which show that protecting the skin can delay the onset of aging. The SUVIMAX studies in France showed that the use of anti-oxidants on the skin slows down the aging process. It is also possible to reduce lines and improve skin firmness.
Benefits of anti-oxidants were detected in grape seeds extracts. After that, cosmetic companies started using these benefits in their skin care products. Grape polyphenols are natural compounds derived from green grape seed extract which have been shown to have a powerful anti-oxidant effect. They shield the skin from the aggression of a wide range of free radicals and are known to help maintain the skin's moisture levels.
In the middle of 1990s Estee Lauder has completed research into understanding more about skin cells losing energy. Dr. Maes, Vice-President Research and Development, Estee Lauder Worldwide, explains: "We cannot make the skin look like when it was in youth. Technologies can decrease the lines by 50%, but we will never decrease them by 100%. We have studied skin samples and found that its thickness is already decreasing from the age of 20. In biological terms, if the cells are losing energy they will also lose their ability to protect themselves against the environment."
He compares this loss of energy to that of a battery running low which needs to be recharged. Thus, to slow down aging and protect the skin cells, manufacturers started using anti-oxidants, sunscreens and skin energizing technologies to "recharge" cells. They are described as a next generation skin nourishers that enable skin to tap into a fuel source of bio-available micro-nutrients.
The scientists have studied different types of skin aging and it means that they are capable of developing skin care which will effectively abate aging. It is recognized that 90% of skin damage is caused by external environmental aging. This includes smoking, wind, chemicals, and, most importantly, UV radiation. The level of pollution increases so quickly that skin cells can not develop self-protection mechanisms. Free radicals or oxidants are naturally generated in the body as a reaction to the aggression of external, environmental factors as well as internal factors such as stress and tiredness. A consequence of this aggression is an acceleration of the skin's aging process. Most of skin damage is done in the early years and people do not see the results of this until they are in their forties and fifties.
The reason for this is due to the skin's chronological aging, which we can do nothing about. Internal, chronological aging is largely a consequence of genetics and affects skin all over the body.
Modern scientific research in skin care and the growing knowledge of the skin's physiology mean that it is possible to stop and even repair skin damage which occurs later on in life. Thus, the latest thinking and research is focused on developing skin protection not from a plain Sun Protection Factor but from the cells themselves. The case in point is a new area of cosmetology (allocosmetics) and skin care products of modern generation of late 1990s, which are based on cell extracts that have lately drawn much attention of scientists. Cells can segment themselves and reproduce identical copies, replace old skin cells by new ones of the same type, take part in biochemical skin processes. This is what we call lifetime self-rejuvenation.
The strides made in anti aging technology over the past decade have been astounding and clearly show no signs of abating. We can be certain that there will be many more exciting achievements in anti aging skin care technology to come.
