Put Some Spring in Your Step With Our March Must Haves

Have you ever noticed how your skin seems to get worse after treating a blemish? It all comes down to the pH of your skin. Phace founder Marisa Arredondo found that most skin care products are far too alkaline for the complexion, which is naturally acidic. This serum (like all of the Phace Bioactive products) is at a pH level as close as possible to skin's natural acidity, so instead of making your pimple panic and your skin flake, it clears you up. I keep the Clarifying Serum ($84) on my desk for sporadic spot treatments.
