Why You'll Love It

Imagine waking up to visibly brighter, firmer, and more even-toned skin — every single morning. Our 20% Vitamin C Serum is a triple-action powerhouse that combines the three most clinically proven brightening and anti-aging ingredients in one lightweight formula. This 20% Vitamin C Serum is designed for real, visible results.

What It Does For Your Skin

  • ✨ Fades dark spots & hyperpigmentation in as little as 4 weeks with stabilized Vitamin C at 20% concentration
  • 💧 Plumps & hydrates deeply with Hyaluronic Acid that holds 1,000x its weight in water
  • 🔄 Smooths fine lines & renews skin texture with encapsulated Retinol that works overnight
  • 🛡️ Protects against environmental damage — pollution, UV stress, and free radicals
  • 🌟 Delivers a natural glow that lasts all day — no filter needed

The Science Behind Our 20% Vitamin C Serum

Most serums oxidize quickly and lose their potency. Our 20% Vitamin C Serum uses a stabilized L-Ascorbic Acid formula at the clinically effective 20% concentration — the highest dose proven to brighten without irritation. Combined with low molecular weight Hyaluronic Acid for deep penetration and time-released Retinol for overnight renewal, this serum works around the clock.

How to Use

  1. Apply 3–4 drops of the 20% Vitamin C Serum to clean, dry skin every morning
  2. Gently press into face, neck, and décolleté
  3. Follow with moisturizer and SPF (essential when using Vitamin C)
  4. Use Retinol at night for maximum results

Pro tip: For best results, use consistently for 8 weeks. Most customers see visible brightening within 2–3 weeks.

Perfect For

  • Dull, uneven skin tone or dark spots
  • Early signs of aging — fine lines and loss of firmness
  • Anyone wanting a natural, lit-from-within glow
  • All skin types including sensitive skin (start with every other day)

Complete Your Routine

Pair this 20% Vitamin C Serum with our Hyaluronic Acid Serum for extra hydration, or our Tamanu Oil at night for deep repair and scar fading.
