    • 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
      • 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

      Amazing stuff

      This was the only thing missing from my regimen. I’ve worked so hard to find a regimen that has kept my skin clear and fixed my hyperpigmentation. I was having problems with oiliness across my forehead and the occasional breakout on my jawline. This cleared me up overnight and I don’t have the same oily forehead. My skin feels so soft and balanced. The smell isn’t great, and smells like feet to me. BUT the product is amazing and I will keep repurchasing.

      Amazing!

      Holy glow, this stuff is awesome. I’ve been using it after hypochlorous acid spray and before my mandelic serum. It has cleared my face and given me a much less oily complexion. It smells like feet though and should come with a warning. Some describe it as “earthy”, but it is unpleasant to me. However, its ingredients are contributing to a glowy and clear complexion so I can get over the smell. This has been a wonderful addition to my regimen.

      Fabulous Find

      I don’t know what it is about this product, but it makes my skin glow AND it helps keep my perimenopausal acne under control. A little goes a long way with this one, so dispense with caution. I like to dispense a drop directly on my forehead and pat in, then a drop on each side of my lower face. I discovered Siv about a year ago and it is an absolute essential.

      Great for rosacea

      This was recommended to me to help with rosacea. It has quickly become a daily routine. Leaves skin soft, not drying, and has helped clear rosacea. Highly recommend!

      HYPE IS WARRANTED

      Now I get the hype around this product. I use the smallest amount on troublesome areas or after extractions to speed up healing. Helpful to calm irritation and redness
