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. Show more
