When applying in the morning, follow with sunscreen.

Technology

We combine advanced stabilised Vitamin C with clean water-only extraction to create formulas that remain potent, gentle and effective, especially for skin affected by dryness, dullness or hard water.

Advanced Stabilised Vitamin C

High strength. Low irritation. Longer stability.
Typical Vitamin C products oxidise quickly, turn brown and can sting sensitive skin.
We use a glycerin-stabilised Vitamin C system that improves absorption, keeps irritation low and slows oxidation for clearer, brighter results.

What It Means for Your Skin

• Brighter, clearer skin with reduced dullness
• High potency that stays stable for longer
• Gentle enough for sensitive and dry skin
• Less prone to browning or breakdown
• A smoother, more comfortable Vitamin C experience

Water-Only Extraction (SWE)

Pure extraction using only heat, pressure and water.
Most brands rely on alcohol or harsh solvents to extract plant ingredients, which can irritate skin or degrade beneficial compounds.
We use Subcritical Water Extraction (SWE), a clean, solvent-free method that keeps actives potent and stable, unlike solvent-based methods that can degrade ingredients.

  • Potent, stable actives from plants, delivered without irritation.
  • Clean, irritant-free formulas for sensitive and dry skin.
