Get the most out of your skin care routine by taking your time. Give your skin at least five minutes to absorb or react to the products before you move on to the next step of your routine — this holds especially true for serums, such as the Peach & Lily Glass Skin Refining Serum, $39. If you're in a rush and you don't have time to go through a lengthy skin routine, keep it simple so your skin still gets the most out of your products.
