This product can help soften the skin and reduce its moisture loss with emollients and occlusives: helianthus annuus seed oil, glycine soja oil.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).
