Meet SIV Serum: A Microbiome-Friendly Innovation Now at Dahlia Beauty Bar
We are SO excited to welcome SIV Serum to our curated skincare offerings at Dahlia Beauty Bar! This innovative, science-backed formula is a groundbreaking approach to skin health that aligns perfectly with our holistic skincare philosophy. SIV was developed by a Detroit-area skincare expert with a microbiologist, who saw firsthand the connection between the skin’s microbiome and long-term skin health. At its core, SIV is a live probiotic serum — created by a small, woman-owned business committed to making skin care smarter, safer, and more supportive of our body’s natural processes.
Instead of relying on aggressive ingredients that strip or overcorrect, SIV introduces beneficial bacteria to restore harmony to the skin’s microbiome — your skin’s unique ecosystem of microbes that regulate oil production, inflammation, and barrier function. What sold me on it was seeing the case studies and before and after photos on little babies who were suffering from extreme eczema. This serum cleared it for them in just a few days. Anything that is effective, natural, science-backed, and gentle enough for babies to use gets a yes from me!
How It Works: The Science Behind the Serum 🔬
Your skin is home to billions of microorganisms that help regulate its health. When this delicate balance is disrupted (often by harsh products, over-cleansing, or environmental stressors), skin becomes more prone to breakouts, irritation, and redness. SIV uses a live strain of Lactobacillus bacteria, known for its ability to: outcompete harmful bacteria on the skin’s surface, reduce inflammatory skin responses, strengthen the skin barrier, promote healing and repair, and support balanced, hydrated skin.
What makes it unique is that it’s alive! This is an active, living probiotic serum that works in real time to shift your skin’s microbiome toward a healthier state.


How to Use SIV in Your Skincare Routine 💧
SIV should be applied as your first serum step, directly after cleansing and toning, and before applying any actives or moisturizers. Because it’s a live product, you want to give it a clean, receptive environment to thrive.
Step-by-step usage:
Cleanse (gentle, microbiome-safe cleanser recommended)
Tone (optional, especially if using hydrating mists or essences)
Apply SIV Serum (1–2 pumps onto damp skin, press gently into face)
Wait 5–10 minutes before layering other products — this gives the live bacteria time to colonize and activate
Follow with your actives (if applicable) such as vitamin C, niacinamide, or hyaluronic acid
Moisturize and SPF (morning) or finishing oil (evening)
If you need help building your skincare routine, book an Introductory Facial or a Skincare Consultation with one of our estheticians to get started!
Pro Tips:
Use SIV both AM and PM for best results.
Avoid applying SIV directly after strong exfoliating acids or retinoids. Instead, use on alternate nights or apply SIV first, wait 10–15 minutes, then apply your actives.
If you’re using benzoyl peroxide or prescription topicals, consult your esthetician or dermatologist on how to layer, as those products can kill beneficial bacteria.
SIV represents everything we believe in at Dahlia: skincare that works with your body, not against it. We’re proud to support a local, woman-owned business crafting a product that is not only rooted in science but also incredibly gentle and transformative. It’s vegan, fragrance-free, cruelty-free, and made in small batches to preserve the integrity of the living probiotics. If your skin is feeling out of balance — whether you're dealing with breakouts, sensitivity, or just want to support your barrier health than SIV Biome Balancing Serum might be the missing piece in your routine. Now available at Dahlia Beauty Bar in-store and online!
