Primer
A primer is the product applied under foundation or eyeshadow for smoother application, better colour pay-off, and long lasting wear. Choosing the right primer depends on your skin type and needs.
Dry skin : Opt for a hydrating primer with a creamier texture.

Oily skin : A mattifying primer with a gel texture works best.

As you can already see there is one for every need. Keep in mind you can always ask for a sample before buying to test it yourself.
