Category: Formulation Philosophy
Most skincare begins with water. It’s inexpensive, lightweight, and easy to formulate—but water also introduces a challenge: the need for preservatives, which can irritate sensitive skin.
For reactive skin, preservatives are often the first ingredient to trigger redness, tightness, or discomfort. Oils, butters, and waxes, by contrast, rarely provoke irritation.
What water does in skincare
Water acts as a filler and solvent, allowing ingredients to spread. Once applied, it evaporates quickly, providing only temporary hydration. Over time, repeated exposure to water-based products can disrupt the skin’s natural barrier, leaving it more reactive.
Why preservatives matter
Preservatives are essential in water-based formulas, but even gentle systems can cause low-grade irritation with repeated use. For sensitive skin, this cumulative effect often goes unnoticed until the barrier is compromised.
The water-free alternative
Water-free formulas eliminate the need for preservatives. Stable, lipid-based ingredients deliver hydration, nourishment, and barrier support without unnecessary risk.
The Alluvia approach
At Alluvia, every formula is water-free, preservative-free, and crafted in ultra-small batches. By reducing unnecessary exposure, we create skincare that works with the skin, not against it.
