The skin microbiome is not just a barrier — it’s a living, intelligent ecosystem. Its balance is critical to health, regulating inflammation, supporting hydration, strengthening immunity, and modulating skin’s response to stress.

That's why Re[Sens] formulas rely on a MICROBIOME-FRIENDLY preservation system — specially tailored for sensitive skin. It is:

gentle yet effective

reduced by 50% without compromising stability

non-disruptive to skin’s physiological equilibrium

reliable in post-opened formula protection

We deliberately avoid harsh chemical preservatives that can disrupt the microbiome or provoke irritation.

Our formulas exclude:

Formaldehyde-releasing agents:
2‑Bromo‑2‑nitropropane‑1,3‑diol (Bronopol), 5‑Bromo‑5‑nitro‑1,3‑dioxane, Sodium hydroxymethyl glycinate, Benzylhemiformal, Quaternium‑15, DMDM Hydantoin, Methenamine (urotropine), Imidazolidinyl urea, Diazolidinyl urea

Harsh preservatives:
Methylchloroisothiazolinone, Methylisothiazolinone (banned in EU creams and wet wipes; only allowed in rinse-off products at minimal concentrations)

Instead, we use mild, modern preservatives compatible with the skin’s natural processes. Re[Sens] cosmetics carefully support sensitive skin health — maintaining efficacy throughout the recommended term and remaining completely safe and comfortable, even for the most reactive skin.
