Two in One

By Kathe Lemon

While many moisturizers promise the moon and deliver considerably shy, Clarins HydraQuench Intensive Serum Bi-Phase makes good. Containing two powerful hydrating agents (Katafray bark extract and Inca Peanut oil), the serum is great as either a spot treatment for extra-dry areas for those with combination skin or all over for those with more general dehydration.

Put it on under your regular moisturizer or sunscreen for day or night use. Not only does the serum add hydration, two of its main ingredients, Katafray bark extract and Hyaluronic acid, actually improve the skin's ability to maintain moisture levels. The serum does separate and needs to be shaken before each application, which some users may find off-putting, but overall it's a great product and a little goes a long way.
