Chest hair trimming, beard shaping, waxing your back - it all falls under the category of 'manscaping.'

The market research firm NPD Group, which looks at buying trends, says one in four men now use some sort of facial-skin care product like face wash or moisturizer. Last year, department stores sold $84.7 million worth of male skincare products. That's up 13% from the year before. All this spending is in an effort from men...to look good.

It's all detailed in the new documentary "Mansome" by director Morgan Spurlock. He explains why he chose to explore men's grooming habits.
