Keep the cap tight and store cool and dark — refrigerate unopened bottles. If the serum turns deep amber, it's oxidized and time for a fresh one.\u003c\/p\u003e\n\u003ch3\u003eVitamin C works best with daily sunscreen\u003c\/h3\u003e\n\u003cp\u003eWe don't sell sunscreen, but it's the one step that protects everything this serum works toward. Without daily SPF, UV light breaks vitamin C down, drives new dark spots and speeds collagen loss — so your serum is left fighting an uphill battle.
