I bought this sun stick because I use the sun gel version and absolutely love it. It is just as hydrating and nourishing. It doesn't leave my skin greasy and is easy to use. It is perfect for topping up, especially if you are out and about and don't want to use your hands. A must-have in the handbag!

It does not smudge make-up, you can apply it as often as necessary. It does not leave a greasy film on the skin and does not smell. Small but can be used for many months and the packaging is smart so you can take it anywhere, even in a small bag. Highly recommend.
