The Science of SIV

Who Will Love It

  • Acne-prone or reactive skin

  • Supporting skin health for those with gut issues like dysbiosis or leaky gut

  • Anyone looking to restore barrier health and achieve truly balanced skin

SIV Biome Balancing Serum is designed to bring harmony back to your skin by supporting its microbial balance with a breakthrough in topical microbiome care: spore-based probiotics.

Why SIV Works

At the heart of this serum are powerful Bacillus spores, including Bacillus subtilis and Bacillus coagulans. These resilient microbes naturally:

  • Increase beneficial bacteria on the skin’s surface

  • Crowd out harmful bacteria, pathogens, and irritants

  • Calm inflammation, breakouts, and redness

  • Enhance hydration and barrier integrity

  • Produce over 24 natural antibiotics and vitamin K2, promoting skin resilience

Through a process called quorum sensing, these intelligent spores communicate with other microbes on your skin, adapting to the unique needs of your individual microbiome and creating a more favorable environment for healthy skin.
