Product description

Vitamin C Serum with Ferulic Acid

20% L-Ascorbic Acid + Vitamin E + Ferulic Acid

A clinical-strength antioxidant serum designed to visibly brighten skin, improve uneven tone, and support collagen production using the most proven form of Vitamin C.


What makes this Vitamin C serum different?

Not all Vitamin C serums work the same.

Many brands use Vitamin C derivatives because they’re easier to formulate — but derivatives are less studied and less potent.

This formula uses:

  • 20% pure L-Ascorbic Acid (the gold-standard, clinically studied form)

  • Vitamin E (Tocopherol) to enhance antioxidant protection

  • Ferulic Acid to stabilize Vitamin C and improve efficacy

This exact combination is widely considered the most effective antioxidant system for skin.


How does this Vitamin C serum work?

Pure L-Ascorbic Acid works by:

  • Neutralizing free radicals caused by UV exposure and pollution

  • Supporting natural collagen synthesis

  • Fading the appearance of dark spots and post-acne marks

  • Improving overall skin brightness and clarity

Vitamin E and Ferulic Acid:

  • Increase antioxidant stability

  • Help Vitamin C remain effective longer on the skin

  • Improve visible results compared to Vitamin C alone


Who should use this serum?

This Vitamin C serum is ideal for:

  • Dull or uneven skin tone

  • Sun damage and dark spots

  • Fine lines and early signs of aging

  • Loss of firmness or radiance

Best for normal, combination, and oily skin types.
If you have sensitive skin, start with once-daily use.


How is this different from most Vitamin C serums?

Most Vitamin C serums on the market:

  • Use lower percentages

  • Use Vitamin C derivatives instead of L-Ascorbic Acid

  • Oxidize quickly due to poor formulation

  • Sit on shelves for months before reaching customers

Dr. Brenner Vitamin C Serum is:

  • Made with pure L-Ascorbic Acid

  • Formulated for stability with Ferulic Acid

  • Fresh-batched every two weeks

  • Shipped directly from our facility to preserve potency

Fresh formulation matters with Vitamin C — oxidation reduces effectiveness.


How to use

  • Apply 2–3 drops to clean, dry skin

  • Use in the morning

  • Follow with moisturizer and broad-spectrum SPF

Avoid combining with strong exfoliating acids in the same routine.


When will I see results?

Most users notice:

  • Increased brightness within 1–2 weeks

  • Improved tone and clarity within 4–6 weeks

  • Continued collagen support with consistent daily use

Results depend on skin type and consistency.


Frequently Asked Questions

Is this the same type of Vitamin C used in dermatologist-recommended formulas?
Yes. This uses pure L-Ascorbic Acid, the most researched and effective form of Vitamin C in skincare.

Why does the serum feel slightly tingly?
A mild tingling sensation is normal with high-strength L-Ascorbic Acid and usually subsides quickly.

Can I use this every day?
Yes. Most users apply once daily in the morning.

Does this oxidize?
All pure Vitamin C can oxidize over time. That’s why we produce this serum in small batches and ship fresh.

Terrible new packaging

I've been using this products for serveral months and have been so happy, but now the new packaging has ruined everything. It doesn't dispense well and I feel there's a lot of waste and no control. Please bring back the glass bottle and dropper!

Same serum but packaging isn't as good

Same serum but packaging isn't as good. I don't think it dispenses well and I have a feeling I won't get as much product out of the container by the end.

Bring Back the Dropper Bottle

I too, do not like the airless packaging. I prefer the dropper bottle as it's more controlled. The airless packaging is more difficult to pump out how much product compared to the dropper. I feel like I'm using more product than I would like with the pump. There's nothing wrong with the formulation, just the packaging.
