Biome Balancing Serum

Biome Balancing Serum is a spore-based microbiome serum designed to work with your skin's natural biology and support a balanced, resilient skin ecosystem.

A proprietary blend of Bacillus spores uses quorum-sensing technology to adapt to your unique skin microbiome. Squalane, caprylic/capric triglyceride and glyceryl caprylate replenish the skin's surface and help it resist moisture loss.

The result is skin that looks and feels hydrated, calm and soothed.

At Crafted Beauty, we're interested in skincare that supports the skin's own ecosystem. SIV's Biome Balancing Serum stood out for its spore-based approach in a simple, lightweight oil base. It's a thoughtful choice for anyone whose skin feels easily stressed, dry or out of balance.
