Sleep is an incredible luxury on so many levels, and it’s prime time for skin to naturally repair itself. According to experts, 7 to 9 hours is optimal for collagen repair, which plumps skin and keeps it from sagging. Sleep is also great for blood flow, which allows that natural glow to shine through. I don’t even need to mention that puffy eyes result from reduced blood flow and show up as dark circles since the skin is so delicate in the area. There are never enough hours in the day, but sleep is more effective than any beauty products money can buy. A perfect antidote to sleep deprivation is Slipsilk, a luxurious 100% silk mask inside and out which outshines all other masks with its thickness, softness, and durability. Slipsilk simultaneously blocks out disruptive and stimulating light while providing a gentle landing spot for the upper cheeks and eyes. Instead of rubbing your entire beauty regimen off, friction is reduced around the delicate eye area to keep it fresh and young.
