Vit-C Plus Crystals

This product is only available in Australia


Pure L-ascorbic acid (antioxidant & brightening) with essential antioxidant crystals.

Vit-C Plus crystals contain the highest pharmaceutical grade of pure Vitamin C (L-ascorbic acid crystals) combined with the innovative skin lightening agent, kojic acid.

L-ascorbic acid is unstable as a water-based serum or cream and will have a short period of effectiveness. But when using the pure L-ascorbic acid crystals in a powder form, the Vitamin C is activated only when a liquid component is added, this way the ingredient is always active for maximum activity on the target cells.



If you need help deciding which essential product is right for you, see our guide to your ABC’s here.


Benefits of pure L-ascorbic acid include:
• Promotes collagen production
• Enhances tissue repair
• Antioxidant protects the skin from harmful UV damage
• Potent anti-inflammatory
• Possesses a skin lightening effect by suppressing excess melanin production

Benefits of kojic acid:
• Reduces the appearance of sun damage and pigmentation
• Powerful antioxidant
• Antimicrobial agent
• Powerful skin lightener


Use in the morning for daily antioxidant protection. Tap a small amount (size of a matchstick head) of Vit-C Plus Crystals into the palm and dissolve at a dosage ratio of approximately 1:4 parts crystals (20% vitamin C) to water.

Alternatively, use it as a booster by adding it directly to your Synergie Skin serums for targeted results:

(Use the same ratio as with water)

HydroGel – oily, acneic skin
SuperSerum+ – ageing skin and fine lines
Vanish – uneven skin tone and hyperpigmentation

For more robust skin types only, Vit-C Plus Crystals may also be combined with Exfol-X as a weekly ‘mini-peel’ to combat congestion, uneven skin tone, and sun damage. Do not combine with A+ or Priority B serums.

If you have a known sensitivity to acidic products, introduce Vit-C Plus Crystals into your routine at a lower dosage over 2-3 weeks to allow the skin to acclimatise.


As part of our commitment to innovation, Synergie formulations are updated from time to time. Always refer to the ingredient list on the box for the most current version.
