We tested the 20% Vitamin C + E Ferulic Acid Serum to see if it lives up to the buzz. Here's our honest review, benefits, and how it compares to other formulas.
Vitamin C serums have become a staple in skincare routines, and for good reason. They brighten, protect, and boost collagen. But with so many options, it's hard to know which one truly delivers. Today, we're diving deep into the 20% Vitamin C + E Ferulic Acid Serum to see if it lives up to the hype.

This serum promises a potent dose of vitamin C, stabilized with vitamin E and ferulic acid for enhanced efficacy and stability. We've tested it for weeks, examining its texture, absorption, and results. Here's our honest assessment.
What Makes a Great Vitamin C Serum?
Before we get into the review, let's talk about what to look for in a quality vitamin C serum. The most effective form is L-ascorbic acid, but it's notoriously unstable. That's where vitamin E and ferulic acid come in. They stabilize the vitamin C, making it more effective and longer-lasting. A good serum should also have a pH level around 3.5 to ensure optimal absorption.
The 20% Vitamin C + E Ferulic Acid Serum checks these boxes. It contains a high concentration of L-ascorbic acid, paired with vitamin E and ferulic acid to boost its stability and efficacy. This combination is often referred to as the 'gold standard' in vitamin C serums.
- Look for L-ascorbic acid as the primary ingredient.
- Check for vitamin E and ferulic acid for stability.
- Ensure the pH is around 3.5 for best penetration.
First Impressions: Texture and Absorption
Upon opening the bottle, you'll notice a light, water-like texture that's typical of high-quality vitamin C serums. It's not sticky or greasy, which is a huge plus. It absorbs quickly into the skin, leaving a smooth, non-tacky finish that layers well under moisturizer and sunscreen.
The scent is subtle, with a slight citrus note that's not overpowering. It's a refreshing change from some serums that smell strongly of hot dog water (a common issue with unstable vitamin C). This serum's pleasant scent suggests good formulation and oxidation control.
Key Benefits and Ingredients
The 20% concentration is potent, making it suitable for those with some vitamin C experience. It's designed to brighten skin tone, fade dark spots, and stimulate collagen production. The addition of vitamin E and ferulic acid doubles its antioxidant power, protecting against environmental damage.
We compared it to other popular vitamin C serums and found it to be on par with far more expensive options. The formula is also free of parabens, sulfates, and synthetic fragrances, making it suitable for sensitive skin types (though patch testing is always recommended).
- Brightens skin tone and fades hyperpigmentation.
- Boosts collagen production for firmer skin.
- Provides potent antioxidant protection against free radicals.
How to Incorporate It Into Your Routine
For best results, apply the serum in the morning on clean, dry skin. Use a few drops and gently press it into your face and neck. Wait a few minutes for it to absorb before applying moisturizer and sunscreen. Vitamin C works synergistically with sunscreen to enhance UV protection.
If you have sensitive skin, start by using it every other day to let your skin build tolerance. You can also layer it with a hydrating serum, like the Hyaluronic Acid + Vitamin C Serum, for an extra boost of moisture and glow.

Potential Drawbacks to Consider
No product is perfect, and this serum is no exception. The 20% concentration may cause a slight tingling sensation on first use, which is normal. If you have very sensitive skin, you might prefer a lower concentration. Also, like all vitamin C serums, it has a shorter shelf life once opened, so it's best to use it within three to six months.
The price point is mid-range, making it more accessible than some luxury brands, but still an investment. However, given its efficacy and the fact that a little goes a long way, it offers good value for money.
So, is the 20% Vitamin C + E Ferulic Acid Serum worth the hype? Absolutely. It delivers on its promises of brighter, more even-toned skin, and its stable formulation ensures you get the most out of your vitamin C. If you're ready to elevate your skincare routine, this serum is a worthy addition.
