SIV Biome Balancing Serum

Spore-Based Probiotic Serum for Acne, Redness & Barrier Repair

SIV Biome Balancing Serum is a spore-based probiotic serum designed to rebalance the skin’s microbiome and calm inflammation at the source.

Powered by resilient Bacillus spores and advanced quorum-sensing technology, this formula adapts to your unique skin environment to support beneficial bacteria, reduce breakouts, calm redness, and strengthen barrier function. Instead of aggressively stripping or suppressing the skin, SIV works intelligently to restore microbial balance, helping skin become clearer, calmer, and more resilient over time.

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
