What the product description says
“This luxurious oil-based Superfood Serum With Reishi from Four Sigmatic is made with real (super)food ingredients such as reishi mushroom spore oil to impart much-needed moisture and give skin a newfound glow.”

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: simmondsia chinensis seed oil, persea gratissima 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).
