Protects against environmental aggressors: A stand-alone primer creates a protective layer on your skin, not just for makeup but also for the world around you.Bonus points if that buffer layer includes soothing actives to calm the skin and dial down redness. Provides a buffer layer: Especially for those with sensitive or acne-prone skin who might find complexion products irritating or pore-clogging, it's important to have some sort of buffer layer between your skin and whatever makeup you're putting on next.Targets skin concerns: Innovative primers of today include skin care ingredients to target specific skin concerns, says Compton, such as oat extract for redness, vitamin C for discoloration, and niacinamide for excess oil.'Blurring primers create a soft veil over the skin, reflecting light and diffusing the appearance of imperfections,' Compton adds.

While there's no way to actually 'shrink' pore size, primers can provide a blurring effect that minimizes their appearance.

Minimizes pore appearance: Primers are beloved for creating a smooth, even base before makeup.

Elevates your makeup: 'Depending on the type of primer you choose, it can provide a matte, dewy, or luminous finish to your overall makeup look,' says makeup artist Alexandra Compton, product development manager at Credo.

If your makeup frequently sweats or flakes off by midday, you might want to invest in the extra step.

Helps makeup last longer: Perhaps their most well-known benefit, 'Primers can help grip makeup, increasing longevity of wear,' notes makeup artist Lisa Aharon.
