There’s no such thing as a miracle treatment when it comes to combating age, though vitamin C comes pretty close. Why? Because it’s a powerful antioxidant that protects your skin from elements like the sun (though it is not a replacement for sunscreen), pollution, and cigarette smoke. Vitamin C also discourages melanin production in the skin, which means it help] hyperpigmentation issues (think brown spots), evens out skin tone, and increases radiance. As if that wasn’t enough, research suggests that when vitamin C is applied to the skin, it significantly reverses aging-related structural changes by influencing collagen and elastin synthesis. A vitamin C serum is the best way to deliver this active ingredient into the deeper layers of your skin.

When to Start Using a Vitamin C Serums
It’s never too late to start using vitamin C because it has the power to suppress skin damage by increasing the protein synthesis of collagen. Not to mention, prevention is probably the best anti-aging arsenal there is. From younger individuals who are starting to see the first signs of aging in their 20s to more mature skin types with or without the visible effects of sun damage, everyone can benefit from using a vitamin C serum.
What to Look for in a Vitamin C Serum
- To get the best vitamin C serum benefits, the first thing to look for is how the vitamin C serum is packaged. While traditionally, dark glass bottles were the preferred material, companies have made a lot of packaging innovations to keep the C stable. When C is exposed to light, the product turns yellow — you don’t want this to happen because it may darken your skin instead of helping with any hyperpigmentation issues. Always store your vitamin C serum in a cool, dark place.
- Next, you’re going to want to choose the right vitamin C serum for your skin type. For example, If you have dry, mature skin, look for more moisturizing serums containing lipid-soluble forms of vitamin C, like ascorbyl palmitate and tetrahexyldecyl ascorbate. If you’re on the oilier side, a serum with L-ascorbic acid and sodium ascorbyl phosphate is better because these ingredients are water-soluble, which means they are lighter and better suited for an oily skin type.
- Lastly, keep an eye out for the concentration level of vitamin C in the serum to ensure its effectiveness. Most experts agree that a level between 10 and 20% is the sweet spot — 8% is too low, whereas going over 20% could cause irritation and isn’t any more effective.

Obagi has been going strong for 32-plus years and has only improved over time, which is why it’s on this best-of list (sidenote: if you haven’t tried their ELASTIderm Eye Cream), you’re missing out.) This no-nonsense vitamin C serum contains one of the highest concentrations of 20% L-ascorbic acid (vitamin C) you can find.

Best for Firming: Dr. Dennis Gross C + Collagen Brighten and Firm Vitamin C Serum ($80)

Best for Sensitive Skin: Drunk Elephant C-Firma Day Serum ($80)
Here’s the fascinating thing about this serum: It has what Drunk Elephant calls a “reservoir effect,” which means the product stays active on the skin for up to 72 hours — even if you’ve washed your face or rubbed your skin. It’s desirable for sensitive skin because it has a pH of 3.3, and is void of essential oils, silicones, and fragrance. What it does contain is a powerful blend of l-ascorbic and ferulic acids to promote a brighter, firmer, and more even-looking complexion. The addition of sodium hyaluronate crosspolymer (a modified form of hyaluronic acid) provides a serious moisture boost while pumpkin ferment extract gently sweeps away dead skin cells.

Best as a Makeup Primer: Maelove The Glow Maker Anti-Oxidant Serum ($27.95)

While it’s suitable for all skin types, the addition of soothing natural extracts like grape, aloe, magnolia, and citrus make it perfect for those with sensitive skin. The hidden benefit of this serum is that it’s also an incredible makeup primer. You’ll be lucky if you can get your hands on a bottle because it is constantly sold out.
Best for Hydrating: Peter Thomas Roth Potent-C Power Serum ($98)

Best French Pharmacy Find: La Roche Posay 10% Vitamin C Serum ($39.99)
This vitamin C serum by La Roche Posay is said to leave skin more radiant, softer, and hydrated. This serum contains 10% ascorbic acid, the active form of vitamin C, that provides several different benefits to the skin. Perhaps the most well-known benefit is its ability to protect the skin from free radicals due to its potent antioxidant activity. Ascorbic acid also supports collagen synthesis and helps to fade dark spots/brighten the skin tone.
Unfortunately, this serum contains a high concentration of denatured alcohol (it is the fifth highest concentration ingredient). Alcohol gives products a quick-drying finish, immediately degreases the skin, and imparts a weightless feel. However, these short term benefits can lead to long term problems. The major problem with using high concentrations of denatured alcohol is that this ingredient is well known to cause skin dryness, irritation, and even disruption of the skin barrier.

The Final Word
Vitamin C is a powerful antioxidant that protects your skin from elements like the sun (though it is not a replacement for sunscreen), pollution, and cigarette smoke. Vitamin C also discourages melanin production in the skin, which means it helps hyperpigmentation issues (think brown spots), evens out skin tone, increases radiance, and stimulates collagen production. When looking for a vitamin C serum, keep an eye out for strength (10-20% is a good benchmark), packaging to ensure stability, and the formula to ensure it’s suitable for your skin type. Everyone can benefit from the power of vitamin C and it’s never too early — or late — to incorporate a vitamin C serum into your skincare routine.
