SIV Biome Balancing Serum
The Living, Spore-Based Microbial Treatment to Rebalance, Reset, and Heal Stressed Skin
Nurture your skin’s ecosystem instead of fighting it. The SIV Biome Balancing Serum is a groundbreaking, biologically smart topical treatment engineered to restore absolute equilibrium to compromised, reactive, and acne-prone skin types. Traditional probiotic skincare relies on fragile, dead, or inactive bacteria strains that sit on top of the skin. SIV utilizes highly resilient, living Bacillus spores that remain safely dormant in the bottle and activate the moment they touch your face. Using advanced quorum-sensing technology, these intelligent microbes "read" your skin's unique signature, selectively targeting overgrown, harmful bacteria while multiplying beneficial species to fundamentally repair a broken barrier.
Why You’ll Love It
A Smart, Adapting Ecosystem: Rather than a one-size-fits-all solution, the living spores read your specific microbial balance, adapting seamlessly to your skin's personal biological needs.
The Ultimate Skin-Barrier Savior: Clinically proven to repair a severely weakened or "leaky" skin barrier, making it the premier choice for conditions like acne, eczema, dermatitis, and rosacea.
Dramatically Lowers Inflammation: In a 317-participant clinical study over 30 days, 89.6% of users reported a dramatic decrease in skin inflammation and a calmer, more uniform complexion.
Crowds Out Breakout Triggers: The active Bacillus spores naturally crowd out acne-causing pathogens and irritants, while producing over 24 natural antimicrobial agents to build long-term skin immunity.
100% Acne-Safe, Ultra-Pure Formula: Contains only four clean, minimalist ingredients, ensuring zero hidden pore-cloggers, synthetic fillers, fragrances, or chemical preservatives.
How It Feels
Texture: A lightweight, silky, fluid oil-serum.
Absorption: Glides on smooth like a dry oil, absorbing beautifully into the skin without leaving a heavy, sticky, or smothering film.
Skin Feel: Instantly soothing, comforting, and deeply hydrating. It relieves the parched, tight, or stinging sensation of a compromised barrier, leaving a soft, natural, healthy satin glow.
The Minimalist 4-Ingredient List
Bacillus Spores (Proprietary Blend): Living, highly resilient soil-based probiotics that activate on contact to restore your skin microbiome's natural balance, defend against pathogens, and stimulate tissue healing.
Squalane (Sugarcane-Derived): A weightless, non-comedogenic, biomimetic emollient that perfectly mirrors your skin’s natural oil structure to lock in deep hydration and maximize elasticity.
Caprylic/Capric Triglyceride: A smooth, nourishing emollient derived from coconut oil that replenishes vital surface lipids and protects against moisture evaporation.
Glyceryl Caprylate: A plant-derived, multi-functional humectant and natural stabilizer that keeps the formula safe while providing exceptional conditioning properties.
How to Use
Use once daily. After cleansing and applying your water-based toners or essences, shake the bottle vigorously to evenly distribute the dormant spores throughout the serum. Dispense 1 to 3 drops into your palms, rub your hands together, and gently press and pat the serum into your skin (can be used on dry or damp skin). Let it set for 30 seconds before layering heavier moisturizers on top.
Esthetician Protocol & The "Rebalancing Response": Because this serum introduces highly active, living spores to your skin ecosystem, roughly 15% of users—especially those with a history of rosacea, eczema, or heavy steroid/antibiotic use—may experience a temporary "rebalancing response" (mild tingling, temporary redness, or an unusual earthy scent). Don't panic! This is a normal sign that the spores are actively restructuring a broken barrier. To smooth out the adjustment period, start by using it at night only for the first two weeks, gradually building up to daytime use.
⚠️ Skincare Interaction Warning: Avoid pairing SIV with Hypochlorous Acid sprays, as the antibacterial nature of the spray can disrupt or kill the live probiotic spores. If you use both, spray your Hypochlorous Acid first, wait 10 to 15 minutes for it to dry completely, and then apply SIV.
