Perché alcuni attivi devono essere attivati al momento dell’uso: stabilità, efficacia e formulazione

Why some active ingredients must be activated at the time of use: stability, efficacy, and formulation

May 06, 2026

Introduction

In the world of advanced dermocosmetics, not all actives behave the same way over time.

Some ingredients, especially the most unstable or biologically active ones, can lose effectiveness just a few hours after preparation. For this reason, more and more professional formulations include activation systems at the time of use.

But what does it really mean? And why can this choice make a difference in results?


The problem of active ingredient stability

Many actives used in facial treatments are sensitive to external factors such as:

  • oxygen
  • light
  • temperature
  • humidity

These elements can alter the chemical structure of ingredients, reducing:

  • effectiveness
  • biological activity
  • ability to interact with the skin

In some cases, the active is no longer functional even before being applied.


What does "activating an active" mean

Activating an active means keeping it separate until the moment of use and combining it only immediately before application.

This happens through specific formulation systems, such as:

  • separate components (powder + solution)
  • activation in the cap
  • biphasic systems

In this way, the ingredient retains its properties until the very last moment.


Why activation improves effectiveness

When an active is used just after activation:

  • is in its most stable form
  • maintains maximum biological activity
  • interacts more effectively with the skin

This translates into greater bioavailability, that is, the ability of the active ingredient to be truly used by the skin tissue.


Unstable actives: why they are also the most interesting

Often, the most effective actives are also the most delicate.

Ingredients such as:

  • advanced antioxidants
  • peptides
  • biological complexes
  • vitamin derivatives

they can degrade easily, but at the same time offer more significant results if used correctly.

For this reason, activation at the time of use becomes a strategic choice.


Traditional formulations vs active systems

Traditional formulations:

  • greater stability over time
  • less complexity
  • but possible loss of effectiveness


Activation systems:

  • maximum freshness of actives
  • greater functionality
  • better skin response


The role in professional protocols

In the most advanced protocols, the activation of actives is not just a formulation choice but part of the method.

Allows you to:

  • work with greater precision
  • optimize every phase of the treatment
  • improve the quality of the result over time

It is an approach that combines formulation technology and understanding of skin biology.


Conclusion

Not all active ingredients are designed to last over time.

Some are designed to work at their best.

And this is precisely why they must be activated at the time of use.

Understanding this difference means taking a step forward towards more conscious, effective, and quality-oriented dermocosmetics.
