Moisturizing

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": mannitol, caprylyl glycol.

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).

inulin 0.85% - 1.3%

Irritation risk:

Concentration: Effectiveness: HIGH

Helps attract water to the upper layer of the skin. Is claimed to support the growth of "good" bacteria in skin (as a "prebiotic"), but the research is lacking

mannitol 0.05% - 0.15%

Irritation risk:

Concentration: Effectiveness: HIGH

Helps to attract water to the upper layer of the skin

caprylyl glycol 0.1% - 0.35%

Irritation risk:

Concentration: Effectiveness: LOW

Helps preserve products and creates a nice product texture
