Moisturising serum. Contains 70% Korean Ginkgo biloba leaf water, a powerful moisturizer. The water from the ginkgo leaves reduces moisture loss from the skin, thereby supporting the skin barrier. The serum contains 10‰ H-Soak It Up™ complex, which is composed of 8 different hyaluronic acids. Light, medium and heavy molar hyaluronic acids richly moisturise the skin in both the superficial and deeper layers. The complex is able to absorb up to 1000 times more moisture per unit mass (including atmospheric moisture) to keep the skin hydrated for longer and deeper. The complex relieves the skin's pulling sensation and balances the hydration needs of oily skin. Clinically proven triple moisturising action: moisturising the top layer of the skin, moisturising the deeper layer and preventing transepidermal water loss; moisturising action lasts for 100 hours. POWER EFFECT 100™ Technology: the natural ingredients in Power 10 serums are extracted in a 100-hour process. The active ingredients are extracted using ultrasound for 72 hours and then stored in a cool place for 28 hours. This unique process ensures the high quality of the ingredients and does not reduce their potency.
