You have been fighting acne for years. You have tried benzoyl peroxide. Salicylic acid. Clindamycin gels. Retinol. The expensive Korean serums. And still, the pimples come back. Every time you think you have it under control, a new breakout appears.
This is not a failure of effort. It is a failure of approach. Most acne treatments target the symptom — the pimple — without ever addressing the root cause. That root cause, in the vast majority of cases, is a disrupted skin microbiome.
Why Most Acne Serums Don't Work Long-Term
Antibacterial acne treatments work by killing bacteria on your skin. The problem? They kill both bad bacteria (Cutibacterium acnes, the main acne-causing bacteria) AND good bacteria (Lactobacillus, Staphylococcus epidermidis, and others that protect your skin).
When you destroy your skin's good bacteria, you remove the natural defence system that would otherwise keep acne-causing bacteria in check. The result: short-term clearing followed by a rebound breakout — often worse than before. This is why so many acne sufferers experience a cycle of clearing and flaring that never ends.
The Microbiome Root Cause of Acne
Acne is fundamentally an inflammatory condition. The bacterial overgrowth of C. acnes happens most easily when the skin's microbial ecosystem is out of balance — when the protective species are depleted and the inflammatory pathways are constantly activated.
Multiple peer-reviewed studies have now confirmed that people with chronic acne have significantly different skin microbiomes compared to people with clear skin. Specifically: lower diversity of bacterial species, depleted populations of Lactobacillus-family bacteria, and higher rates of chronic low-grade skin inflammation.
How Postbiotics Address Acne at the Root ?
Rub It In Serum by Sonnet Wellness contains Lactobacillus Ferment Lysate — the postbiotic derived from Lactobacillus bacteria fermentation. Here is how it works against acne specifically:
• Produces antimicrobial peptides that selectively inhibit C. acnes without harming protective bacteria
• Reduces the chronic skin inflammation that makes skin hospitable to acne-causing bacteria
• Restores the skin's acidic pH (4.5–5.5) — a pH at which C. acnes cannot easily proliferate
• Strengthens the skin barrier, reducing the pore-clogging and bacterial entry that cause comedones
What Customers Experience ?
"My skin stopped breaking out in 2 weeks. I've tried every anti-acne product on the market. Nothing worked until I stopped fighting my skin and started feeding it." — Priya S.
Most acne-prone customers notice reduced new breakouts within 2–3 weeks. Existing acne begins to clear more quickly. Over 6–8 weeks, the frequency and severity of breakouts reduces significantly as the microbiome rebalances.
How to Use for Acne-Prone Skin ?
• Apply 2–3 drops morning and night after cleansing
• Do not combine with harsh actives (retinol, AHAs) in the first 4 weeks — let the microbiome stabilise first
• Follow with a lightweight, oil-free moisturiser
• Mandatory SPF in the morning — UV exposure worsens acne inflammation
Stop burning your skin clear. Start rebalancing what actually causes it.
