Anti-aging creams are predominantly moisturiser-based cosmeceuticalskin care products marketed with the promise of making the consumer look younger by reducing, masking or preventing signs of skin aging. These signs are laxity, rhytids, and photoaging, which includes erythema, dyspigmentation, solar elastosis, keratoses, and poor texture. Despite great demand, many anti-aging 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. A 2009 study at Manchester University, funded by the manufacturer of the cream, showed that a proprietary blend of ingredients had a positive effect after six months of daily application when extrapolated to a twelve month basis of comparison. The statistical methods used to show this have been criticized. Traditionally, anti-aging creams have been marketed towards women, but products specifically targeting men are increasingly common.
Ingredients
Anti-aging creams may include conventional moisturising ingredients. They also usually contain specific ingredients claimed to have anti-aging properties, such as:
Retinoids. In various formulations it has been shown to reduce fine lines and pores.
Epidermal growth factor, to stimulate cell renewal and collagen production in the skin, and strengthen elasticity and structure. In various research epidermal growth factor has been shown to reduce fine lines, wrinkles and sagging. It also has healing and anti-inflammatory properties when applied to skin.
Equol
Alpha hydroxy acids and beta hydroxy acids or other chemical peels. These help to dissolve the intracellular "glue" that holds dead cells together on the skin. The use of this type of product on a daily basis gradually enhances the exfoliation of the epidermis. This exposes newer skin cells and can help improve appearance. AHAs may irritate some skin, causing redness and flaking.
