SymReboot™ L19 is an innovative, probiotic ingredient based on a patented biotechnological process. Developed from the Lactobacillus plantarum HEAL19 strain, it supports the skin's natural microbiome and sustainably strengthens its protective barrier. What initially sounds like high-tech is actually a state-of-the-art way to make skin more resilient, soothed, and healthier from within.
What is SymReboot™ L19?
SymReboot™ L19 is a probiotic active ingredient based on Lactobacillus plantarum HEAL19 , a special lactic acid bacterium produced using an innovative, patented process. Unlike traditional probiotic approaches, which typically use live bacteria, SymReboot™ L19 utilizes inactivated probiotic cells . These cells retain their bioactive structures and can therefore interact directly with skin cells – without stability issues or contamination risks.
The result: The skin benefits from the advantages of probiotic care, while the product remains safe, stable and highly effective.
How does SymReboot™ L19 work in skincare?
Our skin is naturally covered by a finely tuned microbiome – a complex ecosystem of microorganisms that is crucial for a healthy skin barrier. However, stress, environmental pollution, or over-cleansing can disrupt this balance. The result: redness, dryness, tightness, or increased sensitivity.
SymReboot™ L19 addresses this very issue:
-
It supports the natural skin microbiome by strengthening the balance of the microflora.
-
It activates the natural protective mechanisms of skin cells and helps the skin to better defend itself against external stimuli.
-
It soothes sensitive or irritated skin and reduces redness.
-
It strengthens the skin barrier sustainably , making the skin more resilient and less prone to moisture loss.
In short: SymReboot™ L19 helps the skin to help itself – for long-term balance and resilience.
Why is the microbiome so important for beautiful skin?
The microbiome plays a central role in skin health. It protects us from pathogenic germs, regulates inflammatory processes, and influences how well the skin retains moisture. A disrupted microbiome often manifests as irritation, dryness, or blemishes. Probiotic active ingredients like SymReboot™ L19 act like a natural "reset" for the skin flora.
