The Reset

A Elevated Experience. The Same Trusted Formula.

SIV Biome-Balancing Serum - An innovative, spore-based formula designed to work with your skin’s natural biology. The Spore-Based Biome Balancing Serum is a topical formula that adapts to your unique skin microbiome, establishing a healthy skin foundation through quorum-sensing technology.

This personalized approach to skincare harnesses your biology to support and strengthen your skin’s ecosystem at its foundation, helping to build resilience and maintain a balanced skin microbiome. This serum is your go-to solution for hydrating, calming, and soothing skin.

We’ve enhanced your Biome Balancing Serum experience with a refined glass bottle, precision dropper, and a new 30mL size - offering more of the formula you love with the same results you trust.

Lightweight & stabilizing formula containing physiologically identical ingredients that your skin recognizes.

  • Squalane: Biomimetic oil, molecule derived from non-GMO sugarcane that mimics squalene, beneficial in promoting skin hydration
  • Caprylic/Capric Triglyceride: a mixture of caprylic and capric fatty acids derived from palm oil; help replenish skin’s surface and help it to resist moisture loss
  • Glyceryl Caprylate: a natural, plant-based, emollient derived from glycerin and plant fatty acids; restores the oils of the skin, regulates the skin moisture and
    acts as a humidifier to the skin.
  • Bacillus: A proprietary blend of Bacillus spores support a healthy skin foundation
    and visibly improves skin. Positively influencing your unique skin biome and establishing balance. The spores can help improve the skin microbiome by targeting overgrown bacteria, while facilitating the growth of other essential species- effectively balancing the skin microbiome.

Yes! Our serum is intentionally formulated without fillers or suspension agents. Because of this, natural settling and clumps are expected.

On the first shake, you may notice small white particles - these are simply the carriers for the bacterial strains. As the serum is used, these particles become more uniform and form a fine beige sediment at the bottom.

How to use:

  1. Shake vigorously until the sediment is fully dispersed into the liquid.
  2. Apply as usual - any visible particles melt into the skin.

Once the bottle is set down, the ingredients will naturally settle again. This is perfectly normal. Simply shake before each application.
