Last night, Teigen posted a video to her Snapchat and Twitter accounts, showing her period breakouts in their full glory. We can certainly relate—hormone fluctuations before, during, and after our period never fail to trigger some monster-sized cystic breakouts. Sure, we could do what we can with a salicylic acid-based spot treatment, but that's only treating the surface of the skin. A product that contains lactic acid will penetrate the skin at a deeper level, where the infection actually lies. Our favorite formulas are Renee Rouleau's Anti-Cyst Treatment ($46; reneerouleau.com), which also treats surface breakouts, and Sunday Riley's Good Genes ($105; sephora.com).
And don't pick at the spot. It just isn't worth it. We learned the hard way.
