Skipping the primer is a no-no when it comes to make-up longevity. If you have an uneven skin tone, then try Stila’s offering. It contains three colourcorrecting brighteners for your best complexion ever. Those with enlarged pores should opt for this Smashbox beaut, which creates a more air-brushed base for foundation. Our top tip for application? Apply, then wait five minutes before doing your base.
