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.

The Science of SIV

Unlike traditional topical treatments that fight the skin’s microbiome, SIV nurtures it. By supporting microbial balance and reducing systemic inflammation triggered by gut imbalances, this serum helps restore calm, clarity, and resilience to the skin, from the inside out.

Who Will Love It

• Acne-prone or reactive skin
• Eczema, psoriasis, or other inflammatory skin conditions
• Supporting skin health for those with gut issues like dysbiosis or leaky gut
• Anyone looking to restore barrier health and achieve truly balanced skin
  
  

In a 317 participant study over the course of 30 days:

• 87.2% reported reduced redness
• 91.5% of users agreed that skin looked more youthful
• 89.6% of users reported less inflammation
• 89.9% of users reported improved complexion
• 93.4% of users agreed that skin felt more smooth

By supporting the homeostasis of the skin and restoring microbial balance, SIV creates the ideal environment for your other active serums to absorb more effectively and work even better. Think of it as setting the stage for optimal results!
