Unused item. Found at my parents' house. The following is a copy of the product description from the product website: Whitening serum developed by the Faculty of Pharmaceutical Sciences, Fukuoka University. When you think of vitamins that are good for your skin, do you think of vitamin C? Of course, C is said to be effective, but what we are introducing this time is Vitamin E. Gamma-tocopherol, one of its components, is the origin of this slightly unusual name. The Faculty of Pharmaceutical Sciences, Fukuoka University, has researched and examined the usefulness of gamma-tocopherol, a vitamin E that is attracting worldwide attention, for use in skincare, and has developed a system that can efficiently supply it to the skin. Thanks to this, the vitamin D components, which were difficult to penetrate the skin, are now able to penetrate deep into the skin. It has a strong antioxidant and anti-inflammatory effect, preventing skin aging by removing skin rust. It tightens pores and improves skin texture, such as fine lines and wrinkles. Its whitening effect is 20 times that of vitamin C! - Product Name: Gamma System Essence Kit - Contents: Gamma System Essence Solution 1 (25ml) / Gamma System Essence Solution 2 (5ml) - Brand Name: BeautMedico - Manufacturer: Penta Rapport Co., Ltd.
