SIV: The Biome Balancing Serum
Why I Love SIV Serum for Inflammatory Skin Conditions
SIV Serum is a revolutionary topical that introduces bacillus spores to the skin—powerful microbial messengers that help rebalance your skin’s ecosystem. But to understand how this works, let’s take a step back and look at the skin microbiome.
Understanding Your Skin’s Microbiome
Your skin is home to a diverse ecosystem of bacteria, fungi, and viruses. This ecosystem is crucial to the health and function of your skin.
There are two types of microbes that live on your skin:
Resident microbes – These are your long-term microbial allies. They support:
Oil production
pH regulation
Skin cell turnover
Your skin’s immune system
Your default skin type (dry, oily, normal) and tendency toward inflammation or sensitivity
Transient microbes – These come and go, usually lasting less than a day, and are picked up from the environment.
What Makes SIV Serum Unique?
SIV Serum contains bacillus spores, which function as transient microbes. But unlike other transient microbes, they’re not just visitors—they’re messengers.
Through a process called quorum sensing, bacillus spores communicate with your resident microbes by:
Assessing which species are present
Gauging the balance or imbalance of those species
Sending signals to help restore microbial homeostasis
Think of them as the peacekeepers of your skin’s ecosystem, helping restore balance without colonizing the skin themselves.
Why This Matters for Inflammatory Skin Conditions
When the skin loses the ability to regulate its microbiome—whether due to environmental triggers, hormonal imbalances, gut dysbiosis, or harsh products—it relies on the immune system to step in. This is when inflammation presents as:
Acne
Eczema
Psoriasis
Rosacea
Perioral dermatitis
General skin sensitivity or reactivity
✨ Important reminder: Inflammation is not the enemy—it’s your body’s way of trying to protect you.
By helping rebalance the microbiome, SIV Serum supports your skin in regulating itself—without needing to trigger inflammation.
What About “Good” and “Bad” Bacteria?
Many people think of skin microbes in black-and-white terms—good vs. bad.
But it’s not that simple.
Take C. acnes, for example. It’s often labeled as the “bad” bacteria responsible for acne. But in reality:
You want C. acnes on your skin—it plays an important role
Problems arise when it overgrows and throws the ecosystem out of balance
Balance—not eradication—is the goal.
Who Can Use It?
SIV Serum is safe and beneficial for all ages and most skin types. It’s especially helpful for:
Adults with chronic inflammatory skin issues
Kids and babies with eczema (supporting a healthy microbiome from an early age)
Bonus Benefits
In addition to calming inflammation, clinical scans (Visia) have shown SIV Serum may also:
Improve wrinkle depth
Reduce UV damage
Even out skin tone
Minimize pore size
How to Use SIV Serum
✅ When: After cleansing and toning, on slightly damp skin
✅ Shake well before use
✅ Apply:
Dispense 1–3 drops into the palm
Rub hands together and pat gently onto skin
Let dry for 1–3 minutes before applying other serums or moisturizers
Frequency:
For acne: Once daily is typically enough
For eczema, psoriasis, or dermatitis: Twice daily is recommended
