Ingredient callouts
- This product contains acids (lactic acid 0.50% - 1.20%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
- Humectants (glycerin 0.05% - 0.30%, sodium hyaluronate 0.15% - 0.70%, trehalose 3.70% - 5.50% and glycerin 4.20% - 6.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.
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).
