Make-up primers are basically like sanding a wooden floor, they create a smooth, less porous surface onto which you can add longer lasting make-up.
Silicone primers do create a smoother, more flawless feeling finish, but aren't so great for acne sufferers, whereas other primers are formulated to be really nourishing and moisturising - great for dry skin, but perhaps not so much for oilier complexions.
Whatever your skin type, finding the right primer can be a godsend, making your make-up last much longer and brightening your whole look. Check out our pick of the best make-up primers that you need in your life.More
