At almost 31 years old, my fine lines, overstretched pores, and I are finally understanding the bounties of makeup primer. In my 20s, I’d eschewed the stuff as unnecessary, but I’ve since experienced the skin-smoothing splendor a stellar makeup base can instill. So, too, have Amazon shoppers — many of whom swear by the Prime Lab Face Primer from L'Oréal, currently $13 at Amazon.

The L'Oréal Prime Lab Face Primer is a smoothing, pore-whittling primary step that prepares skin for optimal foundation application and maximum makeup longevity. Per the brand, the formula facilitates budge-proof foundation wear for up to 24 hours. The non-comedogenic, creamy formula glides onto the skin, filling in pores and fine lines to instill a blurring, filter-like finish in mere seconds. 

In addition to its instant smoothing effect, L'Oréal’s primer delivers long-term benefits, too thanks to an infusion of dermatologist-approved ingredients known to loosen pore-clogging debris and sweep dead, dull cells from the skin’s surface.

Specifically, it’s spiked with three exfoliating acids, blended at a 1 percent concentration. A trio of impressive actives comprise dermatologist favorites alpha hydroxy acid (AHA) and beta hydroxy acid (BHA), plus lesser-known yet notably pore-clearing lipohydroxy Acid (LHA), a derivative of BHA. Together, these chemical exfoliants slough dead, dull cells from the skin surface, in turn revealing a smoother, brighter complexion over time. Furthermore, oil-soluble BHA and LHA squelch excess sebum, which can make pores appear larger than they actually are.

Shoppers across a spectrum of ages and skin types are enthralled with L'Oréal’s acid-infused, imperfection-annihilating primer. One reviewer says its effects are akin to "photoshopping,” citing its instant filter-like finish. Another fan notes the formula makes makeup “last all day.” Says yet another shopper, the primer “literally erases” the pores around their nose. Finally — a testament to its skincare benefits — one longtime fan swears the primer has rendered their pores “barely visible,” even post-cleanse.
