Anti aging wrinkle
on Jun30 2011
Anti-aging creams are predominantly moisturiser based cosmeceutical skin care products marketed with the promise of making the consumer look younger by reducing visible wrinkles, expression lines, blemishes, pigmentation changes, discolourations and other environmentally (especially from the sun) related conditions of the skin. A comprehensive grading scale for anti-aging of the skin has been validated and categorizes skin aging as: laxity (sagging), rhytids (wrinkles), and the various categories of photoaging, including erythema (redness), dyspigmentation (brown discolorations), solar elastosis (yellowing), keratoses (abnormal growths), and poor texture.
Despite great demand, many such products and treatments have not been proven to give lasting or major positive effects. One study found that the best performing creams reduced wrinkles by less than 10% over 12 weeks which is not noticeable to the human eye. Another study found that cheap moisturisers were as effective as high-priced anti-wrinkle creams. However, recent studies at Manchester University showed that some ingredients have an effect.Traditionally, anti-aging creams have been marketed towards women, but products specifically targeting men are increasingly common.
Many anti-wrinkle creams contain some form of retinal, which have been shown to rejuvenate the skin. The effects of these compounds likely depend on the concentration and how it is made. Clinical studies have demonstrated that the appearance of aged skin can be some what reversed by daily treatment with topical anti-aging agents. According to the website Health Marketplace.com, alpha-lipoic acid, an ingredient found in many anti-aging creams, function in four ways to help the slow skin aging process.
It is a very potent antioxidant and it helps maintain the health of the mitochondria, which is the powerhouse of the cell. When this cell is compromised, it cannot perform youthful repair functions. Also, it helps turn off an inflammatory messenger known as nuclear factor kappa B that can do much damage to the skin.
Alpha-lipoic acid activates a collagen-regulating factor known as AP-1 that turns on enzymes that digest damaged collagen. Another ingredient found in anti-aging cream is glycolic acid, which is the most potent of the alpha-hydroxy acids. It has been shown to aid wrinkle removal in aging human skin. The purpose of this ingredient is to break down old cells at the skin’s surface so they can be replaced with youthful cells from underneath the skin.
