Description

A 4-week pigment corrector powered by 15% pure L-Ascorbic Acid, clinically stabilised at pH 3 to reach the layer where pigmentation actually begins.
Formulated with 5 powerful antioxidants — including Ferulic Acid, EGCG, Glutathione, and Vitamin E — to correct dark spots, prevent new ones from forming, and brighten skin from within.

This isn’t just glow. It’s deep correction — designed to fade pigmentation, boost collagen, and even out skin tone where other serums stop.

4 Week Transformation

Week 1

Early glow kicks in — hydration improves

→ Hyaluronic Acid, Glycerin, and Panthenol boost moisture + barrier function

Week 2

Dullness begins to fade, tone looks more even

→ 15% L-Ascorbic Acid starts reducing oxidative stress + early pigment clusters

Week 3

Brown spots appear lighter, skin texture feels smoother

→ EGCG, Glutathione, and Ferulic Acid accelerate pigment breakdown

Week 4

Pigmentation visibly reduced, skin looks brighter

→ 5 antioxidants work in synergy to inhibit melanin overproduction + prevent recurrence

Tested on 272 participants with dull, pigmented skin. 89% saw visible improvement by Week 4.

What’s Inside — And How It Gets 8X More Effective?

It starts with 15% Pure L-Ascorbic Acid — the most proven form of Vitamin C to fade pigmentation and boost collagen.

Stabilised at pH 3, it penetrates deeper and stays active where pigmentation begins.
Most serums dilute it. This one doesn’t.

Then we added 4 antioxidants that don’t just support — they multiply its power.

● Ferulic Acid → 2X Potency

Prevents oxidation, doubles antioxidant strength, and enhances collagen stimulation.

● Vitamin E (D-Alpha Tocopherol) → 4X Repair
Reinforces the skin barrier, boosts absorption, and protects newly formed collagen from UV damage.

● EGCG (from Green Tea) → 6X Stability
Soothes inflammation, extends Vitamin C’s activity, and strengthens skin’s defence against pigment triggers.

● Glutathione → 8X Correction Breaks down melanin clusters and recycles Vitamin C inside the skin — making every drop work harder, longer, deeper.

The Result?

A serum that’s up to 8X more effective at correcting pigmentation, rebuilding collagen, and restoring even, radiant skin — where other serums stop.

How to use?

PM Routine (Optional)

Frequently Asked Questions

Characteristics

Upon opening the C radiance serum should be transparent with a slight yellowish tint due to the vitamin E in the formula . Due to the L-Ascorbic acid in the formula, the serum will begin to darken in color over time. Please note that this does not mean the formula has become ineffective. You only need to discontinue usage once the formula has become murky brown . Please refer to the cart in the upper sections for further clarity .

It is normal for C Radiance serum for the face to darken after opening due to air and light exposure. The formula will remain effective. It is recommended to be used within 3-6 months after opening with daily application of a pump of serum to the face, neck.

Since there is no fragrance added to this serum, there is a sort of peculiar smell due to the natural scent of ferulic acid and natural Vitamin E within the formula. It dissipates in a minute or 2 after you apply the serum so you don’t need to worry about it lingering.

We would request you to store the serum in the refrigerator .

It should take about 4-8 weeks to see results (depending on the frequency of usage ). However, many users report that they are able to notice a subtle glow after a week or 2 of usage too .

Usage

Yes you can! It is most beneficial during the day due to the antioxidant properties but you can certainly use it in the PM too if you prefer.

You can check out how to use and when to use sections on the upper sections of the page .

Skin Sensitivity

We do not recommend layering this with exfoliating acids (Alpha Hydroxy Acid, Glycolic Acid, Lactic Acid, Mandelic Acid), BHAs (Beta Hydroxy) and Retinols. This is because mixing those ingredients can lead to irritation, so we recommend alternating them. We suggest using Vitamin C in the morning and Retinol OR AHAs in the evening. We also do not use this product along copper peptides(or any other product that uses copper in a significant amount) as they run the risk of cancelling each other out when used together.

Over the counter tyrosinase inhibitors or vitamins like niacinamide, tranexamic acid,alpha arbutin, kojic acid also help brighten skin. MIXING WITH OTHER PRODUCTS : Avoid using Vitamin C at the same time as Retinol, Alpha Hydroxy Acid products (Glycolic Acid, Lactic Acid, AHA, Mandelic Acid) or BHAs (Beta Hydroxy Acid). Use Vitamin C in the morning and Retinol OR AHAs/BHAs/PHAs in the evening.

You can use C radiance serum in your morning skincare routine and the smart ageing complex in your evening skincare routine .

Same as any other active ingredient it is advisable to patch test before use and introduce the active slowly into your routine to allow your skin to get used to it .It is advisable for beginners to start with the beginner friendly 8% l-ascorbic serum before moving on to the 15% serum .If you find that your skin doesn’t respond well it is better to use less potent vitamin c derivatives.

We would advise you to try the beginner’s version of C radiance serum if you have very sensitive skin .
