FAQ: All You Need To Know About Vivier’s Serum 30

Next-generation brightening.

Vivier’s NEW Serum 30 is expertly formulated with 30% Vitamin C – a synergistic blend of 20% Et-VC® (3-O-Ethyl Ascorbic Acid) and 10% L-Ascorbic Acid USP engineered to target moderate to severe hyperpigmentation. This hydroquinone-free serum targets both surface-level and deeper, underlying pigmentation and damage—while helping prevent future discoloration.

As the only serum to combine this precise blend of Vitamin C with our innovative IDS® delivery system, Serum 30 offers superior brightening, comfort, and stability — all while shielding skin with advanced antioxidant and anti-inflammatory benefits.

Here are the most frequently asked questions relating to Vivier’s latest innovation.

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 colour 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 retinol?

Yes, Serum 30 is suitable to use within the same daily skincare routine as retinol.
Since 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

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 colour 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.

I Have Dark Spots: How To Best Treat Them?

Ingredients to look for and treatments that can help fade hyperpigmentation.

Dark spots, sun damage, and post-acne marks – hyperpigmentation wears many faces, but the frustration is always the same. The good news? Today’s most effective treatments, from brightening serums to powerhouse actives, can help restore a luminous, even-toned complexion.

Here are the main ways to treat pigmentation and dark spots:

1. Topical Creams & Serums

The most effective active ingredients include:

Niacinamide: Reduces dark spots and soothes the skin.

Vitamin C: A powerful antioxidant that brightens the complexion.

Azelaic Acid: Ideal for sensitive or acne-prone skin.

Retinol: Stimulates cell renewal and fades dark spots.

Exfoliating Acids (AHA/BHA): Remove pigmented cells from the surface.

2. Dermatological Treatments

For more severe or resistant cases:

Chemical Peels: based on glycolic or trichloroacetic acid.

Laser: targets deep pigmentation.

Cryotherapy: destroys pigmented cells using cold temperatures.

Microneedling + Brightening Serums: stimulates skin regeneration.

Platelet-Rich Plasma (PRP): Used for darker skin tones.

3. Daily Sun Protection

This is essential to prevent new spots from appearing and old ones from getting worse. Use SPF 30 or higher, even on cloudy days (365 days a year!).

4. Prevention & Care

Avoid touching or scratching spots (risk of post-inflammatory spots).

Incorporate lightening treatments into your routine, even after having the spots treated.

Moisturize your skin well to strengthen its natural barrier.

Following these tips should help treat or reduce their appearance. We recommend consulting a professional if the spots persist.

Before getting into how to treat hyperpigmentation, let’s define what the term actually means, shall we?

This umbrella term describes a condition in which the skin is discolored or darkened due to an array of factors. In fact, hyperpigmentation can be caused by past blemishes, eczema and psoriasis flare-ups, melasma, and of course, excess sun exposure. We would argue that sun exposure is at the root of most stubborn hyperpigmentation issues. That is why one of the main steps in treating hyperpigmentation is daily sunscreen application. The sun is not our friend. At least when it comes to keeping a clear, youthful complexion. 

Many of us, myself included, scour the internet to find the miracle product that will save us from our stubborn hyperpigmentation. The sad truth is that treating dark marks is a long process that requires patience and different types of treatments. Topical products can only do so much and more intense treatments like lasers are recommended to really eliminate the issue at its core. That being said, you should always consult your dermatologist with any skin concern you may have.

While topical products aren’t a cure-all solution in most hyperpigmentation cases, they can definitely help. We’ve asked our aesthetician and Tata Harper Specialist Emmanuelle to name a few products that will help you treat your dark spots and reveal a clear, glowing complexion. Here are her recommendations.

EXFOLIATING CLEANSERS

Exfoliation and cell-turnover are very important when it comes to tackling signs of hyperpigmentation. These cleansers contain active ingredients like AHAs, BHAs and brightening ones like Azelaic Acid and Niacinamide that all help fight hyperpigmentation. Ideally, you would use these cleansers as a second step in your double-cleansing routine, following your oil cleanse.

VITAMIN C SERUMS

Vitamin C is a powerful antioxidant known for its brightening properties. It is an ingredient found in most products designed for treating hyperpigmentation. It’s also effective in combatting free radical damage, keeping your skin healthy and glowing! This is definitely a must in a skincare regimen.

TARGETED BRIGHTENING SERUMS

If you’re already using Vitamin C and a good cleanser but need an extra punch, think of incorporating a targeted treatment serum into your routine. These 3 products are packed with active ingredients designed to assist in targeting and improving the appearance of discolouration, leaving the skin more evenly toned and healthy. Lytera is one of our bestsellers and works at brightening the overall complexion, not just the dark spots.

RETINOLS

Topical retinols work by increasing cell-turnover which helps diminish signs of hyperpigmentation quicker and more effectively. They also increase the production of collagen, improve the skin’s texture and help fight signs of aging. Another must in a skincare routine. The con of using topical retinols is that they can be irritating to the skin which is why you should start slow and with a low dosage. If you have sensitive skin, a naturally-derived retinol like the Pai Rosehip Bioregenerate oil might be a better option for you!

HYDROQUINONE

Hydroquinone is an ingredient used to lighten hyperpigmentation. Both of these Vivier products contain 2% Hydroquinone, which is the highest dose you can receive in Canada without a prescription! If you have stubborn dark spots that just won’t leave, Hydroquinone may be a good option for you! People with sensitive skin may not be able to tolerate this ingredient, which is why it’s important to talk to your dermatologist before use.

SUNSCREEN

Sunscreen may be the most important step in fighting hyperpigmentation. In fact, even if you have the best skincare routine full of active ingredients that target dark spots, if you don’t protect your skin with an SPF, you may as well be pouring your products down the drain. Sun exposure is the number one cause of hyperpigmentation as it causes the production of melanin in your skin. No matter the time of year, you need to be applying an SPF of at least 30!
