SIV Biome Balancing Serum

User Guide: shake Biome Balancing Serum, read commitment and instructions.

SIV Biome Balancing Serum (30 ml) is a breakthrough spore-based formula that works with your skin’s natural microbiome to restore balance, calm irritation, and strengthen the barrier. Powered by probiotic Bacillus spores and enriched with squalane, caprylic/capric triglyceride, and glyceryl caprylate, it delivers deep hydration without heaviness while supporting long-term skin resilience.

Dermatologist-tested, fragrance-free, and non-comedogenic, SIV is suitable for all skin types, including sensitive or reactive skin. With regular use, it helps reduce redness, improve texture, and leave skin looking and feeling healthier, softer, and more radiant.

Unlike traditional serums, SIV doesn’t overwhelm or mask symptoms – it adapts intelligently to your unique skin, promoting calm, hydrated, and radiant results.

Cost: £75

How to Use:

To use, shake well and apply 2–5 drops after cleansing (and toner if you use one), before your moisturiser.

Warm the serum between your palms, then press gently into the skin.

Use morning and night for best results.
