Exuviance® Vitamin C Serum Capsules

L-Ascorbic Acid at 20% is one of the most clinically effective concentrations of Vitamin C for topical use. The problem has always been stability. Once a Vitamin C serum is opened and exposed to air and light, oxidation begins immediately. A serum that was fresh at the time of manufacture may have lost significant potency by the time it reaches the patient's bathroom shelf, and continues to lose more with every day the bottle sits open. This is not a minor inconvenience. It means patients pay for a product that delivers less than its label claims by the time they use it.

Exuviance Vitamin C Serum Capsules solve this problem completely. Each single-use, plant-derived capsule contains a precisely measured dose of 20% L-Ascorbic Acid sealed from air and light until the moment it is opened. Fresh, potent and at full strength with every single use. 60 capsules per pack: a 2-month supply at once-daily evening use.

Who Is It For?

• Anyone wanting maximum-potency Vitamin C without oxidation, waste or potency loss over time
• Dull, uneven or photodamaged skin needing targeted brightening at a clinically effective concentration
• Those wanting to support collagen production alongside antioxidant protection
• Post-procedure skin needing antioxidant support once actives have been cleared by a clinician
• Those on GLP-1 medications wanting antioxidant skin protection during body composition changes
• Anyone who has had Vitamin C serums turn orange, yellow or ineffective in the bottle
• Those wanting the assurance of full-strength Vitamin C with every application

How Does It Work?

L-Ascorbic Acid is the most bioavailable and clinically proven form of Vitamin C for topical use. It neutralises free radicals from UV radiation and environmental pollution before they can damage collagen and skin cells, inhibits tyrosinase to reduce melanin overproduction and fades dark spots, and acts as a cofactor in collagen synthesis to support the production of new structural proteins in the dermis. At 20%, it delivers all three of these benefits at a clinically effective concentration. The plant-derived capsule format ensures the L-Ascorbic Acid remains fully stable and at its stated concentration until the moment of use, without the degradation that occurs in opened bottles. Aminofil adds a visible volumising dimension alongside the Vitamin C. Vitamin E works synergistically with Vitamin C to enhance and extend antioxidant protection.

Key Ingredients

• L-Ascorbic Acid 20%: The most bioavailable and clinically proven form of Vitamin C for topical skin application. At 20%, this is maximum-strength concentration for brightening, collagen support and free radical neutralisation. Sealed at full strength in each individual capsule until the moment of use.
• Aminofil: An amino acid derivative that supports visible volumising and skin plumping alongside the Vitamin C and antioxidant complex.
• Vitamin E (Tocopherol): Works synergistically with L-Ascorbic Acid to enhance and extend antioxidant protection beyond what either ingredient provides alone. Published dermatological research confirms the synergistic enhancement of the Vitamin C and E combination.
• Plant-derived capsule (Corn Starch, Glycerol, Carrageenan): A biodegradable single-use delivery format that keeps L-Ascorbic Acid completely stable at maximum potency until the moment of opening.

Benefits

• Maximum-strength 20% L-Ascorbic Acid fresh and at full potency with every application
• Brightens dark spots, sun damage and uneven skin tone
• Supports collagen synthesis for improved skin firmness over time
• Potent antioxidant protection against free radical damage from UV and pollution
• No oxidation, no potency loss, no wasted product
• 60 capsules: a full 2-month supply
• Biodegradable plant-derived capsule format

What Results Can You Expect?

Immediately: a brightening and radiance boost from the first application. At 2 to 4 weeks: visible improvement in skin clarity and early reduction in dark spots with consistent evening use. At 6 weeks: significant brightening and more even skin tone. At 3 months: improved collagen density and sustained brightening with continued use. Every application delivers the same potent, fresh concentration throughout the full 2-month supply.

How We Use It at Face for Soul

As a pharmacist prescriber specialising in skin health, Vitamin C Serum Capsules are one of my recommended alternatives to standard Vitamin C serums for patients who have experienced oxidation issues or who want the assurance of maximum potency with every application. The single-use format also makes them ideal for travel, for patients who use Vitamin C less than daily and do not want an opened bottle degrading between uses, and for ensuring consistent results throughout a 2-month supply without the gradual potency decline that affects every opened Vitamin C bottle.

How to Use

Twist the capsule open at the tip and dispense the contents onto clean fingertips or the palm. Apply to clean skin in the evening and smooth gently until absorbed. Follow with your evening moisturiser. Use one capsule per evening application. In the morning, apply SPF to protect the collagen your Vitamin C is supporting. Products to pair with: Exuviance Overnight Transformation Complex as the following moisturiser step, and Exuviance Daily Corrector SPF 35 or chosen SPF every morning.

Frequently Asked Questions

Is it worth the money?
The capsule format eliminates the primary problem with Vitamin C serums: oxidation and potency loss. At 20% L-Ascorbic Acid per capsule, every application delivers the same fresh, full-strength dose from the first capsule to the last. If you have previously bought Vitamin C serums that turned orange or produced diminishing results, the capsule format represents significantly better real-world value per application.

Why capsules instead of a standard bottle?
Standard Vitamin C serums begin oxidising from the moment the bottle is first opened. The Vitamin C you apply from the bottom of a bottle is significantly less potent than what was in that bottle when it was manufactured. Each capsule eliminates this problem entirely: every application is from a freshly sealed, full-strength dose.

How many capsules come in the pack?
60 capsules, providing a 2-month supply at once-daily evening use.

Can I use it with tretinoin?
Yes. Apply Vitamin C Capsules in the evening after cleansing on evenings when you are not using tretinoin, or alternate evenings. On tretinoin evenings, use tretinoin first. Both provide complementary skin renewal and protection benefits.

Is it pregnancy safe?
Vitamin C Serum Capsules contain no retinoids or hydroquinone. L-Ascorbic Acid at cosmetic concentrations has no established pregnancy contraindications. We always recommend consulting your midwife or obstetrician before starting new skincare during pregnancy.

Is it suitable for sensitive skin?
At 20%, this is a high-concentration Vitamin C and may cause tingling in sensitive skin. Start with 3 times per week and build up to daily use as your skin adjusts. For patients who cannot tolerate L-Ascorbic Acid at this concentration, the Alastin C-RADICAL Defense uses encapsulated Vitamin C that causes significantly less irritation.

Is it suitable for rosacea-prone skin?
High-concentration L-Ascorbic Acid may trigger flushing in some rosacea patients. For rosacea-prone skin, we recommend starting with 2 to 3 times weekly and monitoring tolerance before increasing frequency.

Does it clog pores?
No. The formula is non-comedogenic.

Is it vegan?
The capsule shell is plant-derived from Corn Starch, Glycerol and Carrageenan. Please contact us to confirm full vegan status as formulations can vary.

Is it cruelty-free?
Yes. Exuviance does not test on animals.

Clinical Insight

As a pharmacist prescriber specialising in skin health, I recommend Vitamin C Serum Capsules specifically to patients who have had poor experiences with Vitamin C serums turning orange or producing disappointing results. Oxidation is the reason. The capsule format eliminates it completely. For patients who want the certainty of full-strength 20% L-Ascorbic Acid with every application rather than a declining dose from an opened bottle, this is the most rational Vitamin C format available.

Research and Evidence

L-Ascorbic Acid's mechanism as an antioxidant, collagen cofactor and tyrosinase inhibitor is among the most extensively studied in published dermatological literature. The synergistic enhancement of Vitamin C with Vitamin E is documented in published research confirming significantly enhanced antioxidant protection compared to either ingredient alone. The instability of L-Ascorbic Acid and the problem of oxidation in opened Vitamin C serums is documented in pharmaceutical chemistry research.

How Does It Compare?

Vitamin C Capsules vs standard L-Ascorbic Acid serum in a bottle: Same active ingredient, different stability. Standard bottles degrade from opening. Capsules deliver full-potency Vitamin C with every application. For patients who have had oxidation issues, capsules are the more reliable format.

Vitamin C Capsules vs Alastin C-RADICAL Defense: C-RADICAL Defense uses encapsulated stabilised Vitamin C with 13 additional antioxidants in a single bottle formula. Vitamin C Capsules use high-concentration L-Ascorbic Acid in individual freshly sealed doses. C-RADICAL Defense is the better morning antioxidant serum with its 14-antioxidant formula. Vitamin C Capsules are the better maximum-concentration evening Vitamin C treatment.

Vitamin C Capsules vs skinbetter science Alto Defense Serum: Alto Defense provides 19 antioxidants including a stabilised Vitamin C in a morning serum. Vitamin C Capsules provide maximum-concentration evening L-Ascorbic Acid treatment. Different times of day, different antioxidant approaches, complementary rather than competing.
