Vitamin C Serum with Ferulic Acid, Vitamin E and Hyaluronic Acid

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.
