A potent Korean serum with 23% pure Vitamin C (Ascorbic Acid) to brighten, fade acne scars, and reduce hyperpigmentation. Infused with Tocotrienol (Super Vitamin E), it offers 50 times stronger antioxidant protection than tocopherol, boosting collagen production and fighting free radicals. Sodium Hyaluronate and Allantoin hydrate and soothe, preventing dryness for a plump, radiant complexion. Its lightweight, bi-layered (oil and serum) texture absorbs quickly, leaving a non-sticky, glowing finish. Ideal for all skin types, especially dull or uneven skin tones, but best for those experienced with Vitamin C due to its high potency. Clinically proven to be non-irritating for sensitive skin.

Key Features:

  • For: All Skin Types
  • Best for: Dull, Uneven Skin, Hyperpigmentation
  • Benefits: Brightening, anti-ageing, hydrating, antioxidant protection
  • Vegan, Cruelty-Free, Fragrance-Free, Paraben-Free
  • Size: 20ml (0.67 fl.oz)

After cleansing and toning, apply this serum.

  1. Shake the bottle lightly once or twice to mix the oil and serum layers.
  2. Dispense 2-3 drops onto clean skin.
  3. Gently massage with fingertips, starting from the centre of the face outward, until absorbed.
  4. Follow with a moisturiser; apply sunscreen in the morning.

Tips:

  • Use in the evening to avoid photosensitivity; always apply SPF30+ during the day.
  • Patch test on wrist or neck before first use, especially for sensitive skin or Vitamin C beginners.
  • Start with 2-3 times a week, increasing to daily use as tolerated.
  • Avoid using with AHA, BHA, or retinol to prevent irritation.
  • Store upright in a refrigerator (3-10°C) to slow oxidation; use within 2 months of opening.
  • Expect a natural coppery scent from pure Vitamin C, with no artificial fragrance.
