Abstract: As luck would have it, Boots inventors found that red clover polyphenols, along with those from a wide selection of other plants, impart antioxidant benefits to protect skin—especially in combination. A recent patent application explains.

It is well-known that sunscreens can protect skin against the formation of free radicals caused by sun exposure. An added measure to protect skin is to treat it with antioxidants, which quench free radicals and terminate the chain reaction they propagate that damages the skin.

According to a recent Boots patent application, there is continuing interest among consumers and cosmetic manufacturers to improve skin care products by increasing and maximizing the benefits they can deliver to skin.

Disclosed in this invention are skin care compositions shown to protect the skin more effectively from exposure to exogenous environmental insults. Thus, the present invention relates not only to skin care, but also to methods of providing improved protection against damage to skin caused by sunlight, environmental stress and/or atmospheric pollution.
