Who This Is Made For

Biome Balance Within is ideal for anyone dealing with chronic, non-cystic breakouts, oil imbalance, or dull, easily reactive skin who also suspects their gut might be part of the picture. It’s a great fit if you want to support clearer, more even, more resilient skin from the inside out, and pairs especially well with microbiome-friendly routines and SIV’s Biome Balancing Serum.

"If you’re using all the right topicals and they’re still not helping as much as you expect, based on my experience working with hundreds of acne clients, it almost always comes down to two things: gut imbalance or stress. When those internal pieces are off, the skin will keep reacting no matter what you put on it. That’s why I love Biome Balance Within - it gives you a simple, hormone-free way to support at least one of those internal triggers so your skin can finally calm down, rebalance, and start responding better to your routine."

How It Works on the Gut–Skin Axis


Instead of chasing breakouts only at the surface, Biome Balance Within looks at the root: internal imbalance. Spore-based probiotics promote microbial diversity and help crowd out problematic bacteria, while citrus polyphenols and carotenoids support gut barrier integrity and calm inflammatory signals that show up on the face as oiliness, congestion, and redness. The result is better skin harmony and more consistent clarity.

Bacillus spores

Survive digestion, support microbial diversity, and help regulate internal triggers that affect breakouts, oil, and redness.

Golden Tomato

Antioxidant carotenoids that support firmness, elasticity, hydration, and resilience to UV and environmental stressors.

Vitamin K2

Supports tissue repair, elasticity, and barrier function while helping protect against oxidative and inflammatory damage for stronger, more resilient skin.

Inside the Formula

Spore-based probiotics support a healthy, diverse microbiome that can better regulate inflammation and oil. Golden tomato carotenoids (Lumenato™) help improve firmness, elasticity, and protection against environmental stressors. Citrus polyphenols (MicrobiomeX®) encourage short-chain fatty acid production and a stronger gut barrier, while vitamin K2 (MenaquinGold®) supports tissue repair, elasticity, and overall skin resilience.

Frequently Asked Questions

How does this supplement actually help with acne-prone and reactive skin?

Biome Balance Within supports two of the biggest internal drivers behind stubborn breakouts—gut imbalance and stress. The spore-based probiotics help improve microbial diversity and reduce internal inflammation, while carotenoids, citrus polyphenols, and vitamin K2 support better barrier function and calmer inflammatory responses. When those internal triggers start to settle, the skin becomes less reactive and more consistent.

Can I take this even if I’m already using acne topicals or actives?

Yes. This supplement works alongside your topical routine, not in place of it. Most people with acne-prone skin see the best results when they support both surface-level inflammation (topicals) and internal imbalance (gut and stress). Biome Balance Within helps your skin respond better to the products you’re already using.

How long does it take to see changes in my skin?

Internal changes take time. Most people notice improvements in oil balance, reactivity, and overall clarity within 8–12 weeks, as the gut microbiome begins to rebalance. Consistency is key—taking it daily gives the best results.

Will this help if my breakouts are stress-related?

Yes. While nothing eliminates stress entirely, this formula helps regulate internal inflammatory pathways that become overstimulated during stress. With better microbial balance and improved gut barrier function, the skin is less likely to show stress-induced breakouts, redness, or sensitivity.

Can I take this if I’m pregnant or breastfeeding?

Since this is a nutritional supplement, it’s important to check with your doctor before starting it during pregnancy or breastfeeding. Everyone’s needs are different, and your provider can let you know what’s appropriate for you.
