The word “kime” in Japanese means “texture” and usually describes the smoothness or roughness of objects.
In cosmetics “kime” is typically used to illustrate the skin surface, like skin isotropy or micro relief. When we see a woman with a smooth, silky and even skin, we would say she has “fine kime”.
The importance of this characteristic of appearance resulted in the new approach of skin care: many companies in Japan now provide treatments specifically for “kime” in addition to traditional products for wrinkle improvement. A number of publications about techniques to improve “kime” were released recently, and the general approach is a focus on stimulation of synthesis of NMF and lipids in epidermis and stratum corneum. The upper layers of skin must be sufficiently hydrated and replenished with NMF and lipids in order to create a smooth and even skin surface. One of the key factors often linked to fine “kime” is filaggrin, a protein responsible for synthesis of amino acids in skin. Increase of filaggrin synthesis helps to improve skin isotropy and moisturize. Besides, recently filaggrin is considered an important method in treatment of atopic dermatitis and other skin diseases.
