treat your hands
Every morning, clean your hands with the same product you use on your face, they both deserve the same importance and then apply a few drops of anti-aging serum. While still damp, apply a cream to create a better absorption, try to moisturize after coming out of the shower or washing your hands.
Moisture is really important for your hands, more than for any other part of your body, because they are always exposed to different elements, put to a lot of use and washed frequently, losing their protective oil mantle. This won’t revert sun damage, but it can help by giving your hands a youthful look and protecting them.
