I read this tip in a magazine last week and I swear I am already seeing a difference!
As part of your night regime, take your facial serum and apply it to the tops of your hands. Facial serums can give you added moisture and nutrients to deeper layers of your skin. As you get older, you've likely noticed that your hands are much dryer and more wrinkled then they used to be. A facial serum's attributes can work just as effectively on your hands as they do your face.
I believe serums should be used in addition to your moisturizer so this doesn't replace hand lotion, just an additional TLC for your hands before you go to bed at night.
You may recall my Workaday Tip #86 titled Renew at Night, this tip would be a great one to add to that evening regime!
