What the product description says
“Dark Spots and Dryness Formulation.”
Source: Sephora

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, squalane.

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).

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~4.7–7%
