I cannot express how much I love this illuminating booster. For an instant glow I simply combine the illuminating booster with my favorite beauty serum or moisturizer, which is different depending on the day. This high-powered booster contains concentrated beads filled with vitamin C rich cucumber and lemon extract to help instantly brighten my complexion and even my skin tone. You just add 2 to 3 drops to your favorite serum or moisturizer and mixed together with your fingers in your palm and use it wherever your skin needs an extra boost. It can be used morning or night. I would highly recommend this to anyone looking for a natural beauty skin regimen!
