    • What is a face serum?

      Face serums are lightweight, fast-absorbing liquids, oils or gels that provide highly concentrated doses of key active ingredients. They’re usually made with ingredients that consist of smaller molecules than those found in lotions and creams, making them especially good at penetrating deeply into skin. Think of a serum as a powerful primer.

    • Do I need a serum if I already use a moisturizer?

      It all depends on your skin type, skin concerns and how willing you are to incorporate an extra step into your routine. For those with normal or oily skin types, a serum can be used in place of a moisturizer, though keep in mind we always recommend wearing sunscreen during the day if you plan on spending any time outdoors.

      For those with drier or mature skin, or anti-aging concerns, we recommend layering the serum beneath your favorite moisturizer (or sunscreen).

      As always, we encourage you to experiment and see which set-up works best for you!

    • When should I use Brighten Up Vitamin C Serum?

      Brighten Up should be applied after cleansing (or toning) and before moisturizing. For people who prefer fewer steps in their daily skin care routine, Brighten Up can be used as a standalone moisturizer - whatever works best for your skin type and needs.

    • How is the Vitamin C in Brighten Up different to regular Vitamin C serums?

      Most preparations of Vitamin C (whether naturally-derived or synthetic) are highly unstable, meaning they are prone to oxidizing and losing their potency very quickly.

      We formulated Brighten Up with ascorbic acid polypeptide, a new, water-soluble preparation of Vitamin C that retains its potency far longer than traditional  Vitamin C serums. In addition to its longer-lasting efficacy, ascorbic acid polypeptide is more suitable for use on sensitive skin and offers improved absorption.

    • Is it safe to use Brighten Up Vitamin C Serum before spending time in the sun?

      Absolutely. Our formula does not cause photosensitivity and is totally safe to use before spending time in the sun. That said, be sure to apply sunscreen before you head outdoors!

    • How should I store my serum?

      Brighten Up comes packaged in a black glass jar to protect the formula from direct sunlight which can degrade the longevity and potency of key active ingredients. We recommend storing this product in a cool, dry place and using it within 6 months of opening.
