Contains 3 kinds of vitamins (vitamin C× retinol× vitamin E). A serum that delivers nano-bubbled moisturizing ingredients to the stratum corneum. Customers who purchased it said, "It's moist, but it doesn't feel sticky." We have also received comments such as "I felt plump and firm." ■ Recommended for those who have such problems ・ Those who aim for uniform and bright skin ・ Those who are concerned about the impression of the skin ・ Those who are prone to acne ・ Those who want to gently care for keratin ■ Suitable for all skin types ・Dry skin ・Combination skin ・Oily skin ・Fluctuating skin ■ Product introduction ─ A well-balanced blend of high-quality vitamins that nourish the skin The synergistic effect of □ three vitamins gives the skin a bright, clear, and youthful appearance. Among the many vitamins, we selected "Vitamin C (VC-IP *3)", "Vitamin A (Retinol *3)", and "Vitamin E (Tocopherol *3)", which are oil-soluble and work on the skin for a long time. The synergistic effect of the three vitamins gives the skin a bright, clear, and youthful appearance. ─ Hydrogen nanobubbles penetrate smoothly (*1) and are not sticky □ blending "hydrogen bubble" makes it easier to blend into the skin. When you try it, you will be surprised at how it blends in smoothly and is not sticky like a lotion, which is rare for a serum. The secret is a nano-level hydrogen bubble. Serums that require effects tend to be sticky because they contain a lot of oil-soluble ingredients, but by blending "hydrogen nanobubbles", skin-beautifying ingredients such as vitamins become easier to blend into the skin. In addition, hydrogen itself has the function of moisturizing the skin, improving its texture, and making it transparent and plump. Since it is smaller than the pores, it penetrates (*1) with the skin-beautifying ingredients from between the pores and texture. Another feature of the "Hydrogen Nano Bubble" is that hydrogen, which has small molecules and easily escapes into the air, can be stably stored in the serum for a long time. ─ Contains 13 kinds of amino acids that are the source of the skin A well-balanced blend of nutrients that tend to be lacking in □ moisturizing, firmness, and elasticity of the skin. Among the amino acids that make up proteins that form the basis of the skin, essential amino acids (lysine HCl, leucine, valine, threonine, phenylalanine, isoleucine, and histidine HCl) that cannot be sufficiently produced by the body are blended in a well-balanced manner. It supports moisturizing care and brings out the health of the skin. In addition, the formulation is designed to be adjusted to a PH value close to the skin, aiming for a gentle comfort. ─ The gentleness unique to "skin" with sensitive skin □ Finely adjust the amount of blending so that it can be used every day by people of all skin types. This serum is not specifically for sensitive skin. However, there is a lot of commitment unique to the skincare series "Skin 〇", which has been researched and developed for sensitive skin suffering from skin problems. The biggest focus is on how to deliver beauty ingredients to the skin. The higher the concentration of all the ingredients, the easier it is to reach the skin, but it can also be irritating for delicate skin. That's why instead of increasing the concentration, we adopted a method of increasing the penetration power (*1) with "hydrogen nanobubbles". In addition, we are particular about maintaining freshness until the end to prevent adverse effects on the skin due to oxidation and deterioration of the oil-soluble vitamins in the formula. By combining "vitamin E" with "vitamin C", which originally has high antioxidant power, the antioxidant power is about 4 times higher. By adding a further 5 times more with the blend of "hydrogen nanobubbles", the freshness of the serum is maintained. The container in which the serum is placed is kneaded with an ultraviolet absorber to block light. An airless pump that does not come into contact with air is used to thoroughly prevent oxidation and deterioration of ingredients. Because it is a serum for the skin, it can be used every day even by people with delicate skin types. This is one of those thoughts. *1: Penetration extends to the stratum corneum. *2: Due to dryness *3: All skin conditioning ingredients ■ How to use One bottle lasts about 2 months.
