Whether you suffer from blemishes or don't have time to touch up your base, a primer could be the answer to all your makeup troubles.
From lifting the skin for a taut wide-awake appearance to smoothing the surface or filling in creases, make time to prime.
Look for a product that suits your skin type. Shop around and if you're not sure, have a beauty consultation in store so they can tell you what skin type you are and point you in the right direction.
There's everything from thirst-quenching formulas to matte finishes and illuminating pearlescent particles to give your skin a natural radiance. Decisions, decisions...
As for what it does, the clue's in the name. A primer acts as an undercoat for your foundation, preparing and setting the skin for the next stage. The result? Silky smooth skin in a matter of minutes. That's worth getting out of bed early for.
Long lasting foundation and seamless skin? Remind us why haven't we been doing this again? Here's how it's done.
