Does not contain the most effective ingredients for moisturization. The emollients (cyclopentasiloxane, hexyldecanol) can help soften the upper layer of the skin. Keep in mind though that this product lacks humectants that attract water. You might want to use a separate product with ingredients like hyaluronic acid or glycerin in addition (use before this product for the best results).
