SIV Biome Balancing Serum

Spore-Based Microbiome Serum | 0.5 fl oz or 1 fl oz

A lightweight, minimalist serum that works with your skin's natural biology rather than against it. Powered by a proprietary blend of Bacillus spores and quorum-sensing technology, it reads and responds to your unique skin microbiome — targeting imbalance, calming inflammation, and building a stronger, more resilient skin foundation over time. Only four ingredients, all physiologically identical to what your skin already recognizes.

Who it's for:
Anyone dealing with acne, rosacea, eczema, dermatitis, psoriasis, or any compromised barrier condition. Also a strong daily option for sensitive or reactive skin that doesn't tolerate complex formulas well. Shake vigorously before each use — natural settling and visible particles are normal and expected.

Key Ingredients:

Bacillus Spores (proprietary blend):
Spore-based probiotics including Bacillus subtilis and Bacillus coagulans that adapt to your unique microbiome using quorum-sensing technology. They target overgrown bacteria, support the growth of beneficial species, and help restore microbial balance at the skin's foundation.

Squalane:
A biomimetic oil derived from non-GMO sugarcane that mirrors the skin's own squalene. Hydrates, balances oil production, reduces inflammation, and improves elasticity without clogging pores.

Caprylic/Capric Triglyceride:
A fatty acid blend derived from coconut oil that acts as a lightweight emollient, replenishing the skin's surface and reinforcing its resistance to moisture loss.

Glyceryl Caprylate:
A plant-based emollient derived from glycerin and vegetable fatty acids that restores the skin's natural oils, regulates moisture levels, and supports a healthy barrier environment.
