Lately, my skin has been missing its usual glow, the kind of everyday dullness a good night’s sleep and a little extra water can’t quite fix on their own. So, I decided to put Kiehl’s brand-new 1cc CollaShot Plumping Serum ($78) to the test alongside its cult-favorite Micro-Dose Anti-Aging Retinol Serum ($95), pairing a plumping serum with a retinol serum to build a more complete, well-rounded routine.
