Why We Chose Preservation
When we started, we wanted to offer the purest possible solution — hyaluronic acid powder alone. Practice, however, taught us that the moment water enters the process, biology enters as well. This article explains why we chose preservation and why we see it as part of responsible design rather than a compromise.

Why Pure Powder Is Not Enough
When we began developing the Hyalogos concept, the original intention was simple:
to offer pure hyaluronic acid powder and leave everything else to the user.
No intervention, no added substances, with maximum freedom in use.
Practice, however, confronted us with reality very quickly.
Hyaluronic Acid and Water
The Moment the Problem Begins
Hyaluronic acid itself is a stable substance.
However, once it is dissolved in water, an aqueous solution rich in nutrients is created — an environment suitable for microbial growth.
And this happens regardless of how carefully hygiene is maintained.
During testing we:
- worked with pure powder
- used sterile tools
- stored solutions in the refrigerator
- kept them in closed bottles
Despite this, the solutions repeatedly spoiled.
Sometimes within days, sometimes after weeks — but inevitably.
Why “Being Careful” Is Not Enough
Home cosmetic preparation often assumes that strict hygiene will solve the problem.
From a biological perspective, however, this is a misunderstanding.
Microorganisms:
- are present in the air
- on container surfaces
- on skin and hands
- and can multiply even at low temperatures
An aqueous solution without protection simply gives them time.
And time is exactly what decides.
Preservation as a Form of Responsibility
At this point, we faced a decision:
Either:
- offer an absolutely pure solution with a very short lifespan
or accept that stability is part of safety.
We chose the second path.
Not because we wanted to “add something”.
But because we did not want to transfer biological risk to the user.
Why These Preservatives
Preservation does not automatically mean aggressive chemistry.
As with hyaluronic acid, here too the key factors are selection, concentration and context.
We chose a preservative system based on:
- benzoic acid
- sorbic acid
- gallic acid
These substances:
- belong to commonly used organic preservatives
- have well‑documented safety profiles
- are biodegradable
- and are used in food processing and biocosmetics
At the concentrations used, they do not disrupt the structure of hyaluronic acid, while creating an environment that limits microbial growth.
Stability Is Not the Opposite of Purity
We often encounter the idea that:
“the fewer ingredients, the better”
This is true — if the solution is stable.
In aqueous systems, however, purity without protection means:
- shorter shelf life
- higher contamination risk
- less certainty in use
For us, preservation is therefore not a compromise, but part of responsible design.
An Open Foundation, Not a Ready‑Made Solution
Our serum is not a finished product that “promises results”.
It is a stable foundation that can be worked with further — consciously, individually and safely.
In this sense, preservation:
- protects the structure of the mixture
- provides time and space for use
- allows focus on what matters: understanding the substance
Conclusion
Pure hyaluronic acid powder is an excellent starting point.
But the moment water enters the process, biology takes over.
The decision to preserve did not arise from marketing or convenience.
It arose from testing, experience and respect for the reality of working with aqueous solutions.
Because true quality is not about what we do not add,
but about how the whole system functions over time.
