This groundbreaking innovation in facial care is based on the size of hyaluronic acid molecules. SHISEIDO's unique approach gives the skin more youthfulness: a duo of two advanced serums plumps the skin and gives it volume for increased elasticity and firmer facial contours. Inspired by hyaluronic fillers that fill the skin from within, SHISEIDO's Original MolecuShift Technology ensures that the hyaluronic acid molecules contained are optimally absorbed by the skin. The night filler serum provides the skin with more firmness and elasticity thanks to a technology that transports microhyaluronic acid molecules ideally into the skin. The day filler serum makes the skin visibly firmer thanks to a technology that binds moisture in the skin and effectively plumps it up. Apply the night filler serum and the day filler serum after cleansing and before moisturizing. Dispense one pump into the palm of your hand and gently apply to the face. Dermatologically tested. The Skin Filler is also available as a refill.
