# Propylene Glycol

INCI: Propylene Glycol
Category: Delivery

> A proven solvent and active carrier that stabilises the formula and helps deliver Hyaluronic Acid effectively into the skin.

## What it does

A proven carrier that ensures Sodium Hyaluronate and Collagen remain stable and are delivered effectively into the skin for maximum performance.

## Why we chose it

In the HYALURON PURE and COLLAGEN INFUSION formulations, the actives need a carrier that does not interfere with their function. Propylene Glycol delivers them efficiently while keeping the serum lightweight. Widely used in both pharmaceutical and food applications for decades, chosen for reliability, not novelty.

## Key benefits

Stabilizes the formula so actives stay potent from first pump to last. Enhances delivery of Sodium Hyaluronate and Collagen into the skin. Helps control texture for a smooth, lightweight feel. Supports skin conditioning for a comfortable finish.

## Science notes

Humectant, skin conditioning agent, solvent, and viscosity controller per PIF documentation. Excellent safety profile across pharmaceutical and cosmetic applications. Not present in SILK NIACINAMIDE, which uses Pentylene Glycol for the same carrier and humectant functions.
