Why microbiome-safe skincare matters and how we measure it

More and more scientific research shows how essential the skin microbiome is for healthy skin. This changes how we look at skincare today. Instead of trying to remove bacteria, we’re learning how important balance truly is.

That’s why it’s becoming increasingly important to understand what products really do to the good bacteria on your skin. Not only how they feel, but how your skin reacts to them over time.

At YUN, this has led to the creation of the Microbiome Safe Scoring System. A scientific way to evaluate how skincare products interact with the natural balance of your skin and its beneficial bacteria.

It’s not a label on a package.
It’s a conscious way of developing products based on what your skin needs to stay strong, calm, and balanced.

Why is this important?

Microbiome score

Your skin microbiome does more than you think:

  • It supports your skin barrier
  • It protects against unwanted invaders
  • It helps maintain your pH balance
  • It reduces irritation and inflammation

When products disturb these bacteria, your natural protection can weaken. The more often this happens, the harder it becomes for your skin to recover. Over time, this can lead to sensitivity, acne, eczema, redness, and recurring skin problems.

How do we measure microbiome safety?

Ingredient lists (INCI) don’t tell the whole story.
At YUN, we go further. We look at how the entire formula interacts with your skin.
Each product is tested step by step:

  1. Ingredients – analysed at different concentrations
  2. Formulas – tested for interaction and synergy
  3. Finished products – evaluated for impact on beneficial bacteria

Every formula is carefully built and tested to understand how it behaves on your skin and within its natural ecosystem. We study the composition, ingredient interactions, and the effect on the good bacteria that protect your skin.

Our goal is simple: to create formulations that support, protect, and restore your skin’s microbiome so your skin can maintain its natural balance.

The Microbiome-Safe Score

Each tested formula receives a score from A to E:

  • A = As safe as rinsing with water (the gold standard)
  • E = strongly disruptive to beneficial bacteria

This makes it easy to see at a glance what a product really does for your skin.

What does this mean for you?

At YUN, “microbiome-safe” isn’t a label. It’s a philosophy of care.
It means our products:

  • Respect your skin’s natural balance
  • Avoid unnecessary disruption of good bacteria
  • Help your skin become stronger and more resilient

We always choose what your skin needs in the long run, not quick fixes.

Choosing microbiome-safe products means:

  • Healthier skin that stays balanced
  • Less irritation and more resilience over time
  • Transparency — because you deserve honest information

Every formula is designed to work with your skin, so it can maintain its natural balance. Because true skin health begins where nature and science strengthen one another.
