Product summary
"NITTO SEIKI - Ikukin Probiotic Lotion" is a well-rounded moisturizing product. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. NITTO SEIKI - Ikukin Probiotic Lotion ticks this box. Urea, diglycerin, glycerin and sodium pca in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Pentylene glycol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called
"humectants":
diglycerin, glycerin.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This
is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for
ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: urea
Naturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations
