5 Best Mattifying Primers

Mattifying primers are applied under foundation to keep makeup matte and in place for long stretches of time. Additionally, applying primer helps to smooth out fine lines and large pores, giving your skin an even, flawless appearance. You can find both water-based and silicone-based primers. A good rule of thumb is to match your products. For example, a water-based primer would not mix well with an oil-based foundation. More often than not, a little bit of primer goes a long way, so even a smaller bottle will last you. Much like foundation, mattifying primers have a shelf life of roughly one and a half to two years.
