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.

What It Means for Your Skin

  • Potent, stable actives from plants, delivered without irritation.
  • Clean, irritant-free formulas for sensitive and dry skin.
  • Sustainably extracted to keep your skin calm, clear, and strengthened.

FAQ

  • Yes. We use pure, stabilised Vitamin C designed to stay potent while keeping irritation low.
    However, as with any active ingredient, we recommend doing a patch test first, especially if your skin is sensitive or reactive.

  • Most people notice brighter, smoother skin within 1–2 weeks.
    Dark spots and pigmentation gradually improve over 4–8 weeks, in line with the natural skin turnover cycle.

  • Yes. All KELP C products are suitable for daily, consistent use.
    If you're new to Vitamin C, begin with the 5% Melting Powder or the 3% Marine Cream, then build up as your skin adjusts.

  • Yes. They are designed to work together.
    Recommended order: Melting Powder → Serum → Cream
    You can apply the powder directly on targeted areas or mix it into your serum/cream for full-face use.

  • Yes. Vitamin C pairs best with sunscreen.
    Always apply SPF during the day to protect your skin and maximise brightening benefits.

  • Yes, but not in the same routine.
    Use Vitamin C in the morning and retinol at night to avoid irritation and get the most out of both ingredients.

  • Our stabilised Vitamin C oxidises far slower than standard formulas,
    but it is still a natural Vitamin C. For best freshness:
    • Store in a cool, dry place away from sunlight
    • Keep the lid tightly closed
    • Use within 3 months after opening
    This maintains maximum brightness, freshness, and potency.

  • Vitamin C skincare is generally considered safe, but individual circumstances vary.
    Please consult your doctor for personalised advice.
