Vitamin C Serum with Ferulic Acid, Vitamin E and Hyaluronic Acid
Vitamin C Serum with Ferulic Acid, Vitamin E and Hyaluronic Acid
Product Description
Product overview
A clinical-strength 20% L-Ascorbic Acid antioxidant serum by Dr. Brenner that combines Vitamin E, Ferulic Acid, and Hyaluronic Acid to visibly brighten skin, fade dark spots, support collagen production, and protect against environmental damage. Widely recognized as the most affordable alternative to SkinCeuticals C E Ferulic.
Clinical-Strength Brightening
20% pure L-Ascorbic Acid, the gold-standard form of Vitamin C, fades dark spots and evens skin tone more effectively than weaker derivatives.
Texture & feel
SENSORYClinical-Strength Brightening
20% pure L-Ascorbic Acid, the gold-standard form of Vitamin C, fades dark spots and evens skin tone more effectively than weaker derivatives.
Synergistic Antioxidant Shield
Vitamin C + E + Ferulic Acid work together synergistically, boosting photoprotection up to 8x compared to Vitamin C alone (Duke University research).
Hydration Boost
1% Sodium Hyaluronate draws moisture into the skin while Glycerin and Panthenol support the skin barrier and long-lasting hydration.
Premium Formula, Accessible Price
Nearly identical formulation to SkinCeuticals C E Ferulic ($182) with even higher Vitamin C concentration (20% vs 15%), at roughly 1/8th of the price.
Safety & compatibility
SAFEContains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Vitamin C (L-Ascorbic Acid) is generally considered safe for use during pregnancy and breastfeeding.
Contains Laureth-23, an ethoxylated surfactant that some fungal acne resources flag as potentially problematic for malassezia-prone skin. Most other ingredients are fungal acne safe.
A minimal, clean formula with only 12 ingredients. No heavy oils, silicones, or known pore-clogging ingredients. Very low risk of breakouts.
No added fragrance, perfumes, or essential oils. The faint clinical scent is naturally from the L-Ascorbic Acid itself, which is completely normal.
At 20% concentration with a pH of 3.2, some users experience a mild tingle upon application. This is typical for high-strength L-Ascorbic Acid and usually subsides within seconds.
The 20% concentration is potent. If you have very sensitive or reactive skin, start with every other day application and build up tolerance gradually.
Ingredient breakdown
INGREDIENTSL-Ascorbic Acid (Vitamin C) 20%Proven
The most well-researched and potent form of Vitamin C in skincare. At 20%, this is a clinical-strength concentration that promotes collagen synthesis, neutralizes free radicals, brightens skin, and fades hyperpigmentation.
- Duke University Study (Pinnell, 2001): L-Ascorbic Acid must be formulated at pH below 3.5 to penetrate skin effectively — this serum's pH of 3.2 falls in the ideal range.
- Humbert et al.: 5% Ascorbic Acid cream reduced average wrinkle depth by 7% after 6 months. At 20%, this formula is significantly more potent.
- Synergistic Effect: When combined with Vitamin E and Ferulic Acid, photoprotection is enhanced up to 8-fold compared to Vitamin C alone.
Tocopherol (Vitamin E) 1%Proven
Pure form of Vitamin E that works as a fat-soluble antioxidant. Protects cell membranes from free radical damage, moisturizes skin, and stabilizes Vitamin C in the formula.
- Synergy: Vitamin E regenerates after neutralizing free radicals when Vitamin C is present, creating a recycling antioxidant system.
- Skin Barrier: Supports the skin's natural lipid barrier and helps retain moisture.
Ferulic Acid 0.5%Proven
A plant-derived antioxidant that significantly boosts the stability and efficacy of Vitamins C and E. This is the key third ingredient in the legendary C+E+Ferulic antioxidant trio.
- Pinnell et al. (2005): Adding 0.5% Ferulic Acid to a Vitamin C+E solution doubled photoprotection from UV damage.
- Stability: Ferulic Acid helps stabilize L-Ascorbic Acid and Tocopherol, extending the product's effective shelf life.
- Japan: Approved as a sunscreen ingredient in concentrations up to 10%.
Sodium Hyaluronate (Hyaluronic Acid) 1%Proven
A powerful humectant capable of holding up to 1000x its weight in water. Draws moisture into the upper layers of skin, plumping fine lines and improving overall skin texture and hydration.
- Hydration: One of the most effective moisturizing ingredients available. Naturally present in human skin and connective tissue.
- Anti-Aging: Plumps the skin to temporarily reduce the appearance of fine lines and wrinkles.
Ethoxydiglycol ~20%Functional
A solvent and penetration enhancer that helps dissolve L-Ascorbic Acid and deliver active ingredients deeper into the skin. Also contributes to the thin, fast-absorbing texture of the serum.
- Penetration: Enhances absorption of Vitamin C and other actives through the skin barrier.
- Solubility: Helps keep L-Ascorbic Acid uniformly dissolved in the water-based formula.
Panthenol (Provitamin B5)Proven
A skin-soothing and conditioning ingredient that converts to Vitamin B5 in the skin. Supports the skin barrier, helps with hydration retention, and can calm minor irritation from active ingredients.
- Barrier Support: Promotes skin barrier repair and helps reduce transepidermal water loss.
- Soothing: Anti-inflammatory properties help offset potential irritation from high-strength Vitamin C.
Glycerin ~2%Proven
A classic humectant that draws moisture from the environment and deeper skin layers to keep the surface hydrated, smooth, and supple.
- Humectant: One of the most widely used and well-studied moisturizing ingredients in skincare.
Propylene Glycol ~3%Functional
Acts as a humectant and solvent. Helps attract water to the skin and aids in the uniform distribution of active ingredients throughout the formula.
- Multi-functional: Serves as both a moisturizing agent and a vehicle for delivering actives into the skin.

Where it fits in your routine
ROUTINEApply in the morning after cleansing and toning, before moisturizer. Always follow with sunscreen (SPF 30+). Can also be applied to neck and chest. Avoid mixing with strong AHA/BHA exfoliants in the same routine.
How to use
HOW TO USECleanse & Tone
Wash your face with a gentle cleanser and pat dry. Apply toner if part of your routine and let it absorb. Skin should be clean and dry before application.
Apply 4–5 Drops
Dispense 4–5 drops onto your fingertips or directly onto a dry face. Gently press and pat the serum across your face, neck, and chest. Avoid the eye area.
Wait 1–2 Minutes
Allow the serum to fully absorb before layering other products. A mild tingling sensation is normal and should subside within seconds.
Follow with Moisturizer + SPF
Apply your moisturizer to seal in the serum, then finish with a broad-spectrum sunscreen (SPF 30+). Vitamin C enhances sun protection but does not replace sunscreen.
Who is it for?
WHOPerfect for you if:
- You want to brighten dull skin and fade dark spots or hyperpigmentation
- You are looking for an affordable SkinCeuticals C E Ferulic alternative
- You want clinical-strength antioxidant protection against UV and pollution damage
- You want to reduce the appearance of fine lines and boost collagen
- You prefer a minimal, clean formula without unnecessary fillers
- You have normal, oily, or combination skin
Consider alternatives if:
- You have very sensitive or reactive skin that cannot tolerate 20% L-Ascorbic Acid (try a lower concentration like 10–15%)
- You have extremely dry skin and need a richer, more occlusive serum
- You are prone to fungal acne (Laureth-23 may be a concern)
- You prefer airless pump packaging for better oxidation prevention
- You need a Vitamin C serum that layers well under makeup without any tackiness
Skin type compatibility
SKIN TYPESLightweight, watery formula absorbs almost instantly. Humectant-rich but non-occlusive — ideal for oily skin that needs antioxidant protection without shine.
Balances well across different face zones. Provides hydration without heaviness, works under any moisturizer you choose for drier areas.
Perfect match. The serum delivers potent antioxidant and brightening benefits while maintaining skin's natural moisture balance.
Provides humectant hydration but lacks occlusives. Pair with a rich moisturizer or facial oil on top to lock in moisture for best results.
The 20% concentration and low pH of 3.2 may cause irritation. Start with every other day use and build tolerance. Patch test recommended. Consider a lower-strength Vitamin C if skin is very reactive.
Low comedogenic rating (1/5) and lightweight formula. Vitamin C can also help fade post-inflammatory hyperpigmentation from acne scars. Note: Laureth-23 is flagged by some for fungal acne.

Storage & shelf life
3 MONTHS3 months after opening for optimal potency. The serum may remain usable up to 6 months but effectiveness decreases as oxidation progresses. Discard if color turns dark orange or brown.
Store in a cool, dark place away from direct sunlight and heat. Refrigeration is recommended to slow oxidation and extend freshness. Always close the dropper cap tightly after each use.
Amber glass dropper bottle (1 oz / 30 ml). The dark glass helps protect the serum from light-induced degradation, though airless pump packaging would offer better oxidation prevention.
Yes, under 100 ml / 3.4 oz — TSA and airline carry-on approved. Glass bottle — handle with care and consider a protective pouch.
Frequently asked questions
FAQYes. This serum does not contain retinoids, salicylic acid, hydroquinone, or chemical sunscreens — the common ingredients flagged during pregnancy. L-Ascorbic Acid (Vitamin C), Vitamin E, Ferulic Acid, and Hyaluronic Acid are all generally considered safe for use during pregnancy and breastfeeding. However, always consult your OB-GYN or dermatologist before introducing new products during pregnancy.
Use with caution. While most ingredients in this serum are fungal acne safe, it contains Laureth-23, an ethoxylated surfactant that some fungal acne databases flag as potentially problematic. If you are actively dealing with fungal acne, you may want to patch test first or consider an alternative that avoids ethoxylated ingredients entirely.
Vitamin C can be used alongside retinol, but it is best to separate them — apply Vitamin C in the morning and retinol at night. Avoid layering this serum directly with strong AHA/BHA exfoliants (like glycolic acid peels or salicylic acid treatments) in the same routine, as the combined low pH can cause irritation. If you use chemical exfoliants, apply them on alternate days or at a different time of day.
This serum is best suited for normal, combination, and oily skin types. The lightweight, watery texture absorbs quickly without leaving residue. It also works well for dry skin when layered under a rich moisturizer. Those with very sensitive skin should approach with caution due to the potent 20% concentration and low pH of 3.2 — starting with every-other-day use is recommended.
Most users report a noticeable glow and improved hydration within 1–2 weeks of consistent daily use. Visible improvements in dark spots, uneven skin tone, and hyperpigmentation typically appear after 4–8 weeks. Significant anti-aging results such as reduced fine lines and improved firmness usually require 3–6 months of continuous use. Consistency is key.
Apply in the morning after cleansing and toning, on clean, dry skin. Use 4–5 drops on your face, neck, and chest. Wait 1–2 minutes for the serum to absorb, then follow with your moisturizer and sunscreen (SPF 30+). This serum should be applied before heavier creams and oils for optimal penetration.
This serum has a very low comedogenic rating of 1 out of 5. The formula contains only 12 ingredients with no heavy oils, silicones, or known pore-clogging substances. It is lightweight and water-based, making it unlikely to cause breakouts. Many acne-prone users report positive results, including fading of post-acne marks.
For optimal potency, aim to use the serum within 3 months of opening. L-Ascorbic Acid naturally oxidizes over time when exposed to air and light. The serum starts clear to pale yellow — this is normal. If it darkens to a deep orange or brown, it has significantly oxidized and should be discarded. Storing in the refrigerator can help extend freshness. Dr. Brenner produces in small batches to ensure you receive a fresh product.
Verdict: Dr. Brenner Vitamin C Serum delivers the gold-standard C+E+Ferulic antioxidant trio at a price that makes clinical-grade skincare accessible to everyone. With 20% pure L-Ascorbic Acid, 1% Vitamin E, 1% Hyaluronic Acid, and 0.5% Ferulic Acid, this is one of the most potent and well-formulated Vitamin C serums on the market — rivaling the legendary SkinCeuticals C E Ferulic at roughly 1/8th the price. The minimal 12-ingredient formula is clean, effective, and dermatologist-developed. The main trade-offs are the standard dropper packaging (which allows oxidation) and the high potency that may not suit very sensitive skin. If you want proven, research-backed brightening and anti-aging in a no-nonsense formula, this is one of the best values in skincare.

Quick Product Notes
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.
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

Ingredients Related to Skin Types
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.
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.
