Hello,
Few words about Primers for those of you who still not so sure they need one.
Primers-Magic base or just another marketing way to get your money?
While primers do not actually improve skin in the long term, they enhance it's appearance by tightening pores and boosting elasticity for an evening. Those with uneven complexions will find them worth it too.
How primers work: first- they stop the skin from "drinking" your foundation and second- they stop foundation absorbing to much sebum.
