If you're working a 100 hour week on Wall Street, the last thing you have time for is a proper skincare regimen.

That's where L'Oreal (LRLCY) owned Kiehl's comes into play.

"It's about being skin smart," said Chris Salgardo, president of Kiehl's and author of Manmade: The Essential Skincare & Grooming Reference for Every Man. "You want to pay attention to products that have more than one benefit."

Salgardo estimates a proper skincare regimen costs $60-$70 every six months. Salgardo said the biggest growth products for men include anti-aging products. 

Kiehl's products are not sold on Amazon (AMZN - Get Report) .
