A vitamin C that works
Finally no need to worry about stability and waste product that’s gone bad. Love how it glides on skin and absorbs without feeling greasy. The stick lasted me a long time and I used a small spatula to get every little bit from the bottom at the end! So don’t throw away when the stick no longer pushes up there’s a lot of product inside the tube
