When it comes to skincare, preservatives aren’t the first thing we think about. We usually look at the hero ingredients, the hydrators, the brighteners, the ones that promise visible change.
But preservatives quietly sit in the background, keeping everything safe. And here’s something worth knowing: not all preservatives in skincare are created equal.
Why Preservatives Matter More Than You Think
Without preservatives, that jar of moisturiser on your bathroom shelf wouldn’t last more than a few days. They prevent bacteria, mould, and yeast from growing, so every pump or scoop is as safe and effective as the first.
The Downside of Traditional Preservatives
The problem is, many traditional preservatives are very harsh and can upset the microbiome, the invisible ecosystem that plays a major role in how our skin feels and looks. Especially so during menopause, when your skin is already more vulnerable.
A New Kind of Preservative
Only two weeks ago (mid-August 2025), the next-generation preservative xoBiome® EpiProtect™, found in every Nu Allumé product, was awarded Best Functional Ingredient at the NZSCC (The New Zealand Society of Cosmetic Chemists) 2025 Innovation Zone, right alongside some of the most iconic names in global beauty.
What Makes It Different
Instead of relying on traditional preservative systems that focus solely on controlling microbial growth within the product, EpiProtect™ takes a more sophisticated approach.
It uses a carefully designed blend of multifunctional ingredients that work together to keep the formula safe, stable and effective throughout its shelf life.
Here’s the clever part:
- It makes the water within the formula difficult for unwanted microbes to use.
- It limits the nutrients microorganisms need to grow.
- It helps maintain the stability and integrity of the product over time.
But unlike traditional preservatives, it doesn’t stop there.
When the product is applied to the skin, the preservative concentration rapidly diminishes as it spreads across the skin’s surface. Rather than continuing to act primarily as a preservative, the ingredient functions as a humectant, helping attract and retain moisture within the skin.
In simple terms, it protects the product in the jar, then becomes part of the skincare experience itself.
This approach helps maintain product integrity while aligning with our microbiome-focused philosophy, recognising that every ingredient should contribute to supporting menopausal skin, not simply preserving the formula.
That’s what makes our preservative different. It performs one role on the shelf and another role on the skin.
Why This Matters for You
Every Nu Allumé formulation contains this award-winning preservative technology because once you recognise the microbiome-menopause connection, every ingredient matters, even the preservative.
For us, preservatives should do more than protect our product. They should contribute to supporting the skin environment too.
It’s one more way we’ve created skincare designed to work with the biology of menopausal skin, not against it.
The most important ingredients aren’t always the ones on the front of the pack. Sometimes they’re the ones quietly working in the background.
