Drugstores are finally offering vitamin C serums that work just as well as their luxury counterparts. Many large drugstore skincare brands have introduced vitamin C serums that are very effective without the triple-digit price tag.
So today, let’s talk about the best drugstore vitamin C serums.
The popularity of vitamin C in skincare has grown exponentially in recent years thanks to the multitude of anti-aging benefits it offers the skin.
Vitamin C serums are formulated to deliver this potent ingredient to the skin in stable formulas and in a way that it is effectively absorbed.
Vitamin C targets issues like wrinkles and fine lines, dullness, uneven skin tone, hyperpigmentation, dark spots, and loss of elasticity.

19 Best Drugstore Vitamin C Serums

I purchased and tested several vitamin C serums, and these are the best available at an affordable price.
My Top Picks:
- Best Overall: Timeless 20% Vitamin C + E Ferulic Acid Serum
- Best For Beginners: Klairs Freshly Juiced Vitamin Drop Vitamin C Serum
- Best for Sensitive Skin: Olay Vitamin C + Peptide 24 Serum
- Best For Acne-Prone Skin: La Roche-Posay Pure Vitamin C Face Serum

- Best With Hyaluronic Acid: Naturium Vitamin C Complex Serum
- Best for Over 50: Neutrogena Rapid Tone Repair 20% Vitamin C Serum Capsules
- Best For Brightening: Bubble Day Dream Vitamin C + Niacinamide Tone & Texture Serum
- Best Drugstore Splurge: Vichy Liftactiv Vitamin C Serum
The drugstore vitamin C serums below will be noted as either pure vitamin C (ascorbic acid) or vitamin C derivatives (that convert to pure vitamin C in your skin).
While pure vitamin C will be the most effective, if you have sensitive skin, you may consider a non-irritating vitamin C derivative serum to get the benefits of vitamin C without the irritation.
1. Timeless 20% Vitamin C + E Ferulic Acid Serum
If your skin is not sensitive and you prefer higher vitamin C concentrations, you have several stand-out options at drugstore prices.
My pick for the best drugstore vitamin C serum is Timeless 20% Vitamin C + E Ferulic Acid Serum.
Timeless vitamin C serum is often considered an affordable alternative for Skinceuticals C E Ferulic Serum, which is the gold standard in pure vitamin C serums.
Timeless contains a 20% concentration of pre vitamin C (ascorbic acid), plus vitamin E, and ferulic acid.
The serum is formulated to:
- Brighten dull skin
- Stimulate collagen production for smoother, firmer skin
- Protect skin against environmental stress
- Support skin cell turnover
- Prevent uneven skin texture and tone
If you are wondering what’s so special about this combination of actives, clinical research has found that ferulic acid not only stabilizes vitamins C and E but also doubles its photoprotection (sun protection) benefits.
The water-based serum also contains sodium hyaluronate, the sodium salt of hyaluronic acid, to hydrate, soothe, and plump your skin.
Timeless vitamin C serum has a lightweight texture that absorbs quickly without leaving any sticky or greasy residue.
The only drawback to this serum is that sometimes the packaging leaks and runs down the side of the bottle.
I think that’s a small price to pay for an excellent vitamin C serum that delivers a high concentration of vitamin C with additional protective and hydrating ingredients.
And the price is certainly right.
2. CeraVe Skin Renewing Vitamin C Serum
CeraVe Skin Renewing Vitamin C Serum contains 10% pure l-ascorbic acid (pure vitamin C), three essential ceramides, hyaluronic acid in the form of sodium hyaluronate, and vitamin B5.
Pure vitamin C provides antioxidant benefits like protection from UV exposure (sun damage) and environmental stressors. It also helps to brighten the skin and support an even skin tone.
Ceramide NP, Ceramide AP, and Ceramide EOP replenish the skin’s natural moisture barrier. Vitamin B5 helps to soothe the skin.
The serum also contains CeraVe’s proprietary MVE Technology that delivers key ingredients over time for better hydration and nourishment for up to 24 hours.
This CeraVe vitamin C serum is non-comedogenic, meaning it won’t clog pores.
It is also fragrance-free and paraben-free. I love that it’s lightweight, absorbs quickly, and works well under makeup.

3. The Ordinary Ascorbic Acid 8% + Alpha Arbutin 2%
The Ordinary Ascorbic Acid 8% + Alpha Arbutin 2% is a water-free stable solution of pure vitamin C plus 2% alpha arbutin.
This serum is all about brightening. Pure vitamin C offers antioxidant, brightening, and anti-aging benefits, while alpha arbutin interrupts melanin formation to reduce hyperpigmentation, dark spots, and uneven skin tone.
This is one of 8 vitamin C products offered by The Ordinary. I included this serum as one of the best drugstore vitamin C serums for a few reasons.
First of all, it contains pure vitamin C, not a derivative.
No matter how effective a vitamin C derivative is, it won’t be more effective than pure vitamin C.
This serum contains 8% ascorbic acid, which is not too strong and not too weak. It’s ideal for most skin types, as it is much less irritating than vitamin C products at 20% or higher concentrations and is still very effective.
Alpha Arbutin is a bonus, as it helps to brighten dark spots and can be used with other skincare products without any contraindications.
This lightweight formula has a bit of an oily feel to it upon application, but it goes away after the serum is absorbed.
If you’d prefer an effective but more stable vitamin C alternative, The Ordinary Ascorbyl Glucoside Solution 12% (shown above) comes in a water-based serum with a more comfortable texture than waterless vitamin C formulas.
For more on this vitamin C derivative, please see my complete review.
The Ordinary offers other strong, pure vitamin C and vitamin C derivatives, so for more details on all eight vitamin C products from The Ordinary, be sure to check out this guide to The Ordinary vitamin C products.

Upon application, this serum may have a slightly warming feeling, which can happen with pure vitamin C products.
The inclusion of dimethicone (a silicone) makes this serum glide smoothly across the skin and work really well under makeup.
It’s paraben-free, mineral oil-free, synthetic dye-free, and suitable for sensitive skin.*

The addition of plant-derived ceramides helps to strengthen your skin barrier, improve moisture retention, and protect against environmental stressors.
The Benefits of Vitamin C in Skincare
Vitamin C, also known as ascorbic acid, or l-ascorbic acid, is a water-soluble compound that offers several benefits for the skin.
It has potent antioxidant properties that help protect the skin from free radicals due to UV exposure which can damage the skin.
Vitamin C also improves collagen synthesis. Vitamin C inhibits tyrosinase, an enzyme involved in melanin (pigment) production, so it can reduce the look of hyperpigmentation, dark spots, and uneven skin tone. Plus, it has anti-inflammatory and reparative properties.
When should you use a vitamin C serum? Applying a topical antioxidant like a vitamin C serum during the day under sunscreen can provide even more effective UV protection than just sunscreen alone.
The Drawbacks of Vitamin C in Skincare
There are some drawbacks when it comes to formulating ascorbic acid (pure vitamin C) in skincare.
Ascorbic acid is notoriously unstable in skin care products and will degrade when exposed to light, air, and heat. When vitamin C degrades, it darkens and turns a brownish color, which indicates that it is losing its potency.
Vitamin C is tricky to stabilize, and you should use most pure vitamin C formulas within three months of opening. This is where vitamin C derivatives come into play.
Many vitamin C derivatives are formulated to be not only stable but also provide many of the same benefits as pure ascorbic acid. Unfortunately, they are usually not as potent as ascorbic acid.
Depending on the concentration, pure vitamin C may also irritate the skin.
I personally experience more irritation at 20% or 25% concentrations.
Combining Vitamin C With Other Actives
Since pure vitamin C is a potent active, you should avoid using it in the same routine as other strong actives such as alpha hydroxy acids (i.e. glycolic acid and lactic acid), beta hydroxy acids (salicylic acid), and retinol.
Also, since ascorbic acid is formulated at a low pH to be effective, it may compromise the effectiveness of higher pH actives like peptides and niacinamide, so it’s best to use them at different times of the day or on different days.
Final Thoughts on the Best Drugstore Vitamin C Serums
If you are looking to incorporate more anti-agers into your skincare routine, using an affordably priced drugstore vitamin C serum like the ones from this post is the way to go.
The best affordable vitamin C serum will work with your skin type and skin concerns.
The drugstore serums in this post provide the benefits of vitamin C while also using other actives to offer additional benefits.
Some of the serums contain sodium hyaluronate (hyaluronic acid), which is excellent for dry skin, or niacinamide for brightening and balancing oil production, a favorite of those with acne prone skin.
The best drugstore vitamin C serum for your skin will work with your skin type and skin concerns to give you the results that you want. (The best vitamin C serum for me won’t have a concentration of pure vitamin C above 15%-20% since it irritates my skin.)
Just remember that results don’t happen overnight, and you need to stay consistent with your skin care routine for best results.
Regardless of which vitamin C product you choose, adding a vitamin C serum to your skincare routine will help address the visible signs of aging while protecting your skin from environmental aggressors like UV exposure from the sun and pollution.
