Why it's different

Vitamin C + ferulic acid pairing

This serum combines ascorbic acid with ferulic acid, a documented pairing that extends vitamin C's shelf life and antioxidant potency on skin. Glycerin and panthenol add hydration and skin-conditioning support, creating a formula suited to mixed routines.

Stabilized antioxidant system

Ascorbic acid and ferulic acid work together to neutralize free radicals and maintain potency longer than vitamin C alone.

Hydration layer

Glycerin draws moisture into the skin, while panthenol acts as a humectant and skin-conditioning agent.

Reduced oxidative stress

Glutathione provides additional antioxidant support, complementing the vitamin C system.

Lightweight delivery

Water-based formulation absorbs quickly without occlusive ingredients, making it easy to layer under other treatments.

Safety & compatibility

SAFE
Safe during pregnancy

Ascorbic acid and supporting ingredients are considered low-risk in pregnancy. However, always consult your healthcare provider before introducing new actives.

Fungal-acne compatible

The INCI list contains no known triggering ingredients for fungal acne, making this serum suitable for malassezia-prone skin.

Vitamin C requires pH consideration

Ascorbic acid works optimally at low pH (around 3.5). Confirm this serum's pH if layering with other actives.

Potential irritation for sensitive skin

Ascorbic acid can cause mild tingling or redness in first-time users or reactive skin. Start with lower frequency (2–3 times weekly) and build tolerance.

Layering with retinol is possible

Vitamin C and retinol can be used together, but apply to completely dry skin and wait 15+ minutes between applications to minimize irritation risk.

Store away from light and heat

Ascorbic acid degrades quickly when exposed to air, light, and heat. Keep the bottle sealed and store in a cool, dark place.

Not a replacement for sunscreen

While vitamin C has some antioxidant benefit, it does not provide UV protection. Use SPF 30+ daily when using this serum.

Ingredient breakdown

INCI

Ascorbic Acid Proven

Pure vitamin C in its most bioavailable form. It neutralizes free radicals, supports collagen synthesis, and is associated with a brighter skin tone. Ascorbic acid works best in acidic formulations and pairs synergistically with ferulic acid for enhanced stability and potency.

  • Benefit: Reduces oxidative stress and free radical damage
  • Mechanism: Penetrates skin and acts as a coenzyme in collagen synthesis
  • Function: Provides antioxidant defense and brightening support
Most clinically researched form of vitamin C for topical skincare.

Ferulic Acid Supporting

A plant-derived phenolic compound that stabilizes ascorbic acid and amplifies its antioxidant activity. Ferulic acid also has its own free-radical scavenging properties and improves skin resilience when combined with vitamin C.

  • Function: Extends shelf life and efficacy of vitamin C
  • Benefit: Synergistic antioxidant defense with ascorbic acid
  • Research: Often paired with vitamin C in clinical formulations for superior results

Glycerin Supporting

A humectant that draws moisture from the environment into the skin. Glycerin is non-irritating, lightweight, and enhances hydration without occlusion, making it ideal in fast-absorbing serum formats.

  • Mechanism: Humectant that increases skin hydration
  • Benefit: Improves skin barrier hydration and softness
  • Function: Reduces transepidermal water loss when used with occlusive layers

Panthenol Supporting

The provitamin form of pantothenic acid (vitamin B5). Panthenol hydrates the skin, reduces irritation, and supports barrier function. It also enhances skin conditioning and is well-tolerated across all skin types.

  • Benefit: Soothes and hydrates without irritation
  • Function: Supports natural moisture barrier
  • Mechanism: Converts to pantothenic acid in the skin to enhance hydration and resilience

Glutathione Supporting

A tripeptide antioxidant that works alongside vitamin C to combat oxidative stress. Glutathione is particularly valued in skincare for its potential to support skin brightening and overall redox balance, though it has lower bioavailability in topical form.

  • Benefit: Additional antioxidant protection
  • Function: Supports skin barrier defense against environmental stressors
  • Research: Studied for potential brightening and radiance benefits in combination formulas

How to use

4 STEPS
1

Cleanse & tone

Start with clean, slightly damp skin after toner.

2

Dispense 2–3 drops

Drop into palms or directly onto face — a little goes a long way.

3

Pat to absorb

Gently pat into skin until fully absorbed. No need to rub.

4

Layer & seal

Follow with moisturizer to lock it in. Sunscreen the next morning.

06

Who is it for?

FIT CHECK

Perfect for you if

  • You want brightening support and antioxidant protection from a fast-absorbing serum
  • You're building a multi-step routine and need a compatible base layer
  • You have oily to combination skin that needs hydration without heaviness
  • You're open to active ingredients but prefer gentle stabilized forms
  • You want to layer this serum under treatments like retinol or niacinamide

Consider alternatives if

  • You have severely reactive or compromised skin barrier—start with lower active concentrations
  • You expect immediate visible results—vitamin C works gradually over weeks
  • You need an occlusive moisturizer replacement—this serum requires a cream layer
  • You want an all-in-one product—this is a treatment serum, not a full routine

Yes. The ingredient list contains no known malassezia triggers, making this formula compatible with fungal-acne-prone skin.

Most users notice improved radiance and tone around week 4. Vitamin C works gradually, so consistency and patience are key to seeing full benefits.

This is a treatment serum and should be layered under a moisturizer. The serum provides hydration and actives, but a cream or lotion will seal in moisture and support barrier health.

Skincarisma verdict

Calliel's Vitamin C Serum is a stabilized ascorbic acid treatment designed for brightening and antioxidant support. The formula pairs vitamin C with ferulic acid—a clinically-backed pairing that extends potency—and includes hydrating glycerin and skin-conditioning panthenol. It absorbs quickly and layers well in multi-step routines. The main limitation is that ascorbic acid may irritate sensitive skin on first use, requiring gradual introduction. Best suited for oily to combination skin seeking a lightweight, active-rich serum.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
