I have learnt more about the need for facial serum in the past few days and wonder why I ever went without it, I am using the arbonne re9 serum and the difference is amazing.... Often overlooked and sometimes discounted, a good facial serum is essential to a powerful and effective anti-aging skin care regimen. The main reason you'd want to use a facial serum is to get added nutrients into deeper layers of your skin that a regular moisturizer may not be able to reach. A face serum is able to penetrate into all three layers of the skin because it is made of smaller molecules. The serums ability to go deeper into the skin is what allows it to help combat many common beauty complaints. A face serum is a clear, liquid beauty product applied to the face and neck area. Face serums come in many different varieties and are often meant to target a specific problem. They can be used to help fight the signs of aging such as lines, wrinkles, and dark spots. They can also be used to help prevent acne and brighten the skin. Choose a serum that is clinically proven and contains collagen supporting ingredients. In addition the serum should visibly firm and lift the skin while diminishing the appearance of fine lines.
