Key Ingredients

Even the appearance of skin discolourations with 4 powerful antioxidants for brighter, more radiant skin.

  • 15% L-Ascorbic Acid (Vitamin C): brightens the appearance of skin discolourations to reveal an even, radiant complexion
  • 2% Gluconolactone (PHA): gently exfoliates skin so Vitamin C can absorb into fresh, renewed surface layers
  • 1% Feverfew Extract: enhances skin’s naturally occurring antioxidants to support protection against drying environmental aggressors, such as pollution, that could worsen uneven tone
  • Green Tea Extract: boosts Vitamin C antioxidant capacity

Apply to clean, dry face, neck and décolletage every morning, and follow with a NEOSTRATA moisturizer. Store upright in a cool, dark place and open with care as contents may be under pressure. Product color may change over time but remains effective.

Pro Tip: Use an SPF face cream every day - even when it's cloudy outside - to help fend off dark spots and uneven skin tone. For best results, choose a broad spectrum SPF of 30 or above and reapply sunscreen at least every 2 hours, more frequently for fairer skin types.
