Your skin has an ecosystem. This serum works with it.
SIV Biome-Balancing Serum is an innovative spore-based treatment designed to support and balance your skin's unique microbiome rather than aggressively stripping or overriding it.
Powered by a proprietary blend of Bacillus spores, the formula uses quorum-sensing technology to interact with the skin's existing microbial environment and help establish a healthier-looking, more balanced skin foundation.
Its ultra-minimal, biomimetic formula combines Squalane, Caprylic/Capric Triglyceride, Glyceryl Caprylate + Bacillus spores to support hydration, comfort and skin resilience.
Especially helpful for skin that looks or feels:
Red
Reactive
Blemish-Prone
Unbalanced
Dehydrated
Textured
SIV's published before-and-after results show improvements in the appearance of redness, blemishes, hydration, texture, tone and overall skin clarity with consistent use.
Less fighting your skin. More supporting its biology.

How To Use
How To Use
Shake vigorously before every application.
Natural settling and visible beige or white particles are completely normal with this formula.
Apply 1–3 drops once daily to clean skin.
Gently pat into dry or slightly damp skin.
Use after cleansing or toning and before moisturizer.
Zina Tip: Do not skip the shake. Those little particles you see are part of the spore-based formula—they're supposed to be there.
SIV intentionally formulates the serum without fillers or suspension agents, so the spores will naturally settle again after the bottle sits. Simply shake before your next use.
