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 K

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.
