Biome Balancing Serum
"If you struggle with acne, rosacea, eczema, or dermatitis, SIV is such a game-changer. It helps balance the skin microbiome so your skin feels calmer, clearer, and more resilient. I love how lightweight it is, you can use it morning or night without it interfering with the rest of your routine."
Laziza S
Bacillus Spores
Probiotic bacteria that help support the skin microbiome by rebalancing microbial populations and reducing inflammation.
Squalane
Lightweight, stable, and non-comedogenic emollient derived from olives or sugarcane that moisturizes, softens, and protects the skin barrier.
Glyceryl Caprylate
Natural, plant-based, emollient derived from glycerin and plant fatty acids; restores the oils of the skin, regulates the skin moisture and acts as a humidifier to the skin.
Biomecult
“Pair with SIV Biome Balancing Serum for a complete inside-out microbiome approach. SIV rebalances the skin microbiome topically while Biome Cult supports gut microbiome diversity and the gut-skin axis from within.”
Biojuve
“Apply after SIV as your moisturizing step to lock in the spore technology and support the barrier while the microbiome rebalances. The barrier cream and spore serum work together to reduce reactivity and restore skin comfort.”
Squalane is the stable version of an oil your skin already makes, and it suits dry, reactive and acne-prone skin without clogging pores. Here is the one-letter difference that matters on a label and where it belongs in your routine.
Your skin is covered in bacteria doing useful work. Here is the difference between prebiotic, probiotic and postbiotic, and what supporting your microbiome actually does.
Unlike standard probiotic skincare, the Biome Balancing Serum uses resilient Bacillus spores that can survive harsh conditions and activate on the skin where they’re needed most. These spores work intelligently, targeting harmful bacteria and fostering beneficial ones for a more balanced microbiome.
Yes. The serum’s calming blend of spore-based technology and hydrating emollients helps reduce the appearance of redness and soothe irritation, making it ideal for sensitive or reactive skin.
Absolutely. The lightweight, non-comedogenic formula won’t clog pores and helps regulate the skin’s microbiome, which can improve clarity and reduce congestion over time.
Since hypochlorous acid can disrupt the skin’s microbiome and may kill the spores in SIV, it’s best to avoid pairing them. But if you do use both, apply the hypochlorous spray first, wait 10–15 minutes, and then apply SIV so the spores have the best chance to thrive.
Yes, this serum layers well with most routines. Apply after cleansing and before heavier creams or oils to let the spore technology and hydration work effectively.
