- Why We Love It: There is little not to love about this sought-after La Roche-Posay serum. The formula itself is quite gentle—hyaluronic acid, glycerin, vitamin B5, and the label’s prebiotic thermal water come together for a versatile serum apt at hydrating, soothing, and strengthening the skin barrier. That said, its excellent to quell—or prevent—dryness or alleviate skin sensitivities, pairing well with virtually any other ingredient in your routine. I most like its thick, almost syrupy (it's not sticky!) texture that's a sensorial experience on its own—sinking in weightlessly for wear under face moisturizer and/or makeup.
