Our Signal Peptides Firming Serum is one of our founder Karen Behnke's favorite Juice Beauty skincare products. Inspired by the science of epigenetics this micro-serum, formulated with active plant lipids from sunflowers, rice peptides and blueberries, melts into your skin restoring firmness and skin elasticity. Using the self-loading dropper, apply this luxurious serum all over your face, neck and décolleté to feel more sculpted and lifted. Rub any excess product onto the backs of your hands.
