The pharmaceutical grade Vitamin C in this formula, L-Ascorbic Acid USP, is the purest, most potent, and bio-available form of Vitamin C available. Traditionally difficult to stabilize in formulations, this gold-standard ingredient is a cornerstone of Radiance Serum, made possible by our exclusive IntraDermal System (IDS)®. This proprietary delivery system protects the Vitamin C and enhances penetration into all skin layers, with 2x more Vitamin C retention in the skin overall and 4x more in the dermis, while resisting oxidation to maintain maximum potency and consistent, visible results.

Directions

For best results, apply Serum 30 twice daily to clean, dry skin.
If desired, you may apply your favorite Vivier eye cream before use.

Place 2 to 3 drops of Serum 30 in the palm of your hand and use fingertips to apply a thin layer to face, neck, chest, and back of hands as desired, once or twice daily.

Once Serum 30 is fully absorbed, finish your skincare routine:
AM: Apply other target products, moisturizer and sunscreen.
PM: Apply other target products and moisturizer.

To maximize product shelf life, store your serum in a cool, dark place and ensure the dropper cap is tightly sealed after each use.

FAQ

Who should use Serum 30? Is it only meant for skin with visible hyperpigmentation?
Serum 30 is for anyone looking to protect, brighten, and improve their skin, not just those with visible hyperpigmentation. Its high-potency hybrid Vitamin C formula defends against daily environmental damage while delivering powerful brightening benefits. That said, it’s especially ideal for those struggling with moderate to severe hyperpigmentation, as it works deeply to reduce discoloration and prevent future pigment formation.

How long does a bottle of Serum 30 last?
With twice daily use of 2-3 drops per application, a bottle will last approximately 3-4 months. For maximum efficacy, we recommend the product be used within 6 months after opening.

It is important to note that due to the high level of pure and potent L-Ascorbic Acid USP in the formula, it is normal for the formula to yellow over time due to air and light exposure. This natural color change does not substantially affect the product's efficacy. Should your serum turn an orange/deep amber, it is best to replace the product. To maximize product shelf life, store your serum at room temperature and ensure the dropper cap is tightly sealed after each use.

Can Serum 30 be used with a retinol?
Yes, Serum 30 is suitable to use within the same daily skincare routine as retinol.
Due to the fact that Serum 30 has a low pH and retinol is most effective at a higher pH we recommend using one of the following three strategies for maximum results:
1. Wait at least 30 minutes after applying Serum 30 before applying your Retinol
2. Use Serum 30 in the morning and Retinol in the evening
3. Use Serum 30 and Retinol on alternating evenings

Please consult your skincare provider with any questions.

When & How should I apply Serum 30?
Serum 30 can be used both morning and night. For optimal results, apply twice daily as part of your skincare routine.

Although some prefer applying serums directly from the dropper, to prevent potential contamination, we recommend dispensing 2 to 3 drops of Serum 30 into your palm and using fingertips to apply a thin layer to face, neck, chest, and back of hands as desired. A general rule to follow when layering products is to apply them from thinnest to thickest texture.

What colour should Serum 30 be?
L-Ascorbic Acid USP (pure Vitamin C), the primary ingredient in Vivier’s Vitamin C serums, may gradually develop a light-yellow hue over time. This natural color change does not substantially affect the product's efficacy. Thanks to our propriety IDS delivery system which shields naturally unstable Vitamin C molecules from oxidation, our serums are known to maintain their clarity and efficacy longer than other Vitamin C serums on the market.

To further maximize the shelf life of your Serum 30 we recommend tightening the dropper securely after each use, storing your serum at room temperature, and using it within 6 months of opening to ensure optimal results. Should your serum turn an orange/deep amber, it is best to replace the product.

How long does it take to start seeing results?
Many of our customers see and feel an improvement in their skin in as little as one use, however, individual outcomes may vary. Given the natural skin cycle is approximately 28 days long, when used consistently and as directed, customers tend to see significant, noticeable results in as little as 4 weeks. We recommend taking before and after pictures to assist in tracking progress.

Is Serum 30 safe to use after professional procedures?
Yes, Serum 30 is suitable to use as soon as one day post non-ablative procedures. Always consult with a physician or provider for individualized post-procedure care.
