The Chi-Chi Milk Face Pack contains whey* extracted from Miyahira milk. The amino acids contained in whey are very close to NMF, a natural moisturizing factor produced by the skin itself in the stratum corneum of the skin, and naturally blend into the skin and easily penetrate into the stratum corneum, supplementing the water-retaining component of dry keratin cells. In addition, the moisture barrier function of human-type ceramide, sodium hyaluronate, and cholesterol protects the skin from dryness and external stimuli caused by UV damage. In addition, isomerized sugar, a moisturizing ingredient that is similar in structure to sugar and is difficult to flow with water, binds to moisture like a magnet and retains moisture for a long time, and water-soluble B vitamins panthenol retain moisture in the skin, prevents roughness, and makes the skin firm and elastic. The rich cream, which is as rich as milk, has a texture that blends smoothly without being too sticky, and can be used at any time regardless of the scene, and keeps the skin lively and healthy during the day and while sleeping at night. [Whey] It is the supernatant liquid that is present when you open yogurt. Whey contains a variety of nutrients and is attracting attention for its beauty benefits. Whey is said to have excellent water retention and moisturizing power, and the amino acids contained in whey are very close to NMF (a natural moisturizing ingredient produced by the skin itself) in the stratum corneum of the skin, and it naturally blends into the skin and easily penetrates into the stratum corneum, so it supplements the water retention component of dry keratin cells. In addition, the lactose component holds moisture, replenishes the skin's moisture, and prevents dryness. It gently cares for old keratin and makes it easier to peel off excess keratin left on the surface of the skin, and the moisturizing ingredients penetrate the softened stratum corneum, so it is also excellent for exfoliation.
