Some skin care scientists have suggested that regular shaving helps a man to keep a youthful face.

A person’s skin cells, they note, are renewed about every 30 days, and old cells need to be exfoliated.

Shaving helps in this process, the scientists say, by removing dead skin cells in addition to its intended purpose of getting rid of facial hair.

As more men turn to multi-product regimens to help keep their skin looking fresher and younger, advanced shaving gels, skin-conditioning ingredients formulated into shaving creams and new designs in razors themselves are helping give men the added benefits they are demanding.

For instance, Procter & Gamble Co.’s six Gillette Series shave gels introduced earlier this year each deliver a unique benefit to men’s skin.

The line’s moisturizing formula contains glycerin and cocoa butter to nourish skin, while the Gillette Series Cool Cleansing formula contains menthol and eucalyptus oil to provide a cooling sensation that leaves skin feeling refreshed; and the fine’s Protection formula uses almond off to reduce razor drag and prevent irritation.

Improvements in razor technology are also moving the shaving market forward.

The new Azor razor from King of Shaves Co., for example, is said to provide a better shave because it bends.
