As Seen In Vogue.

Give your skin a daily dose of essential nutrients with our Barrier + Beyond Vitamin Water Serum—a lightweight, fast-absorbing formula that provides instant hydration with hyaluronic acid and strengthens your skin’s defense mechanisms. Like an IV for your skin, this water-based serum delivers a potent blend of plant peptides, vitamins A, B3, C, E, and K, each working to nourish, shield, and support a healthy skin barrier.

Vitamin C brightens and defends against environmental stressors, while vitamin B3 (Niacinamide) complex boosts hydration and soothes sensitivity. Vitamin A targets the signs of aging, and vitamins E and K help reinforce the skin’s natural barrier.

Build your Clean Skincare Routine

  • Step 1

    Cleanser + Exfoliator

    Gently massage your cleanser onto damp skin using circular motions, allowing it to lift away impurities, excess oil, and makeup.

    Use an exfoliator or a face mask two times per week to remove dead skin cells and unclog pores. New exfoliator coming soon!

  • Step 2

    Toner

    After cleansing and/or exfoliating, apply a toner to your skin using a cotton pad or by gently pressing it in with your hands. This helps remove any leftover impurities, balance your skin’s pH, and prepare it for better absorption of serums and moisturizers.

  • Step 3

    Barrier + Beyond

    Give your skin a vitamin boost. Apply a small amount to skin after cleansing and toning both day and night.

  • Step 4

    Treatments

    Gently apply treatments, such as under-eye products or blemish solutions, to clean skin using your fingertips or an applicator.

  • Step 5

    Moisturizers

    Morning/Night: Apply a moisturizer suitable for your skin type to clean, slightly damp skin using upward, circular motions. This helps lock in hydration, nourish the skin, and support a healthy, radiant complexion.

    Note: If you're using Blue Dew or Face Cream, these are applied after oil-based serums (like Pro-Age Serum)

  • Step 6

    Oil Serums

    Night: Apply your oil-based serum (ex: Pro-Age or Hydra-Glow) as the final step in your routine to lock in moisture and target skin concerns in the deeper layers of the skin.

    Note: If you're using Blue Dew or Face Cream, these are applied after oil-based serums (like Pro-Age Serum)
