Take care of rough skin just by applying foundation!

Development of Skin Care Powder with a New Component to Control Rough Skin
What’s possible with the research?
Discovery that the component causing skin roughness is actually found on the skin surface—leading to the development of special powder for skin care while wearing makeup!
Rough skin refers to the state where the skin is dry with peeling and uneven texture. This causes uneven application of foundation, and in worse cases, inflammation and redness of the skin. What is happening inside rough skin? First, we find an enzyme responsible for protein degradation: it is called plasmin and is widely present in the epidermis of the skin. This plasmin originates from an enzyme called plasminogen, activated by another enzyme, urokinase, to change into plasmin, which in its turn has a negative impact on the skin.
Enzymes may be associated with positive effects on the skin, such as from enzyme drinks. However, there are many types of enzymes, and some, such as urokinase, activate other enzymes and trigger a negative impact on the skin. This award-winning technology takes its origin from the discovery that urokinase is actually found on the surface of the skin. Until then, it had been generally agreed that rough skin should be prevented by moisturizing. However, since it was proved that urokinase, the cause of rough skin, exists on the skin surface, it became possible to prevent rough skin by simply removing this substance. As a result, we developed a special powder for use in foundation. This technology prevents rough skin through skin care in the morning and at night, as well as during the day while wearing makeup.
What makes this powder special?
Components which draw in and neutralize enzymes! Effect to prevent rough skin has been confirmed by formulating these in powdery foundation!
As a result of examining the powder substance effective on urokinase, we have found that zinc oxide suppresses the activity of urokinase, and silica and talc adsorb it. Simultaneous formulation of these substances makes it possible to draw urokinase together and suppress its activity. However, these powders do not function appropriately when formulated separately. Therefore, two types of composite skin care powder were developed which combined zinc oxide with silica and talc.
These powders were used in the ELIXIR foundation in 2001, as well as the main foundation products of Shiseido such as INTEGRATE, gaining popularity for the element of surprise that a foundation can have a skin care effect, as well as improved application of makeup. As a result of further research, materials with higher applicability than talc and silica have been discovered, leading to formulation of smooth-textured face powder and liquid formulation such as creams and balm. This powder has been applied in more than 600 products since this award was received.
