Benefits of Vitamin C for Skin: What You Need to Know

Over the past several months, I’ve really started to feel more comfortable in my skin as it clears up and becomes much more even. When I do get acne, it clears up quickly and my hyperpigmentation is the faintest it’s ever been. I didn’t even have to spend a lot of money or time for these results to come fast… just one product— or type of product, rather— is to thank.

Vitamin C has made such a huge difference for my combination acne-prone skin, and it’s so easy to incorporate into your routine! Keep reading to discover the benefits of Vitamin C for skin, and the products that I’ve been using to get clearer, brighter and beautiful-when-bare skin.

What Vitamin C Does for Skin

Vitamin C is a powerful antioxidant and works to brighten skin, fading and preventing hyperpigmentation as well as neutralizing free radicals for anti-aging benefits. “Vitamin C promotes collagen production which is essential for generating healthy new skin and improves skin texture, evens the tone of the skin and reduces skin discoloration,” explains Ivy league-trained, Double Board Certified Facial Plastic Surgeon Dr. Jacob Steiger. “It also improves hydration and moisture to create brighter, healthier skin.”

To go more in-depth, check out this video from Doctor Anne, a Germany-based medical doctor who shares the science behind skin care on her YouTube channel. Doctor Anne points out that Vitamin C also “has many benefits that might support fighting acne […] being anti-inflammatory and in helping with postinflammatory hyperpigmentation. It will both inhibit the production of melanin by inhibiting the enzyme Tyrosinkinase, so less dark spots appear in the first place, and lighten the appearance of already existing brown spots.”

How to Use Vitamin C in Your Skin Care Routine

According to Dr. Steiger, Vitamin C is ideal for all skin types and should be applied 2 times a day for the best results. My favorite way– and what I’ve found to be most effective– is to use serums, which are concentrated for maximum effect. You should apply your serum before moisturizer, and after toning and exfoliating. This ensures proper absorption into the skin.

Downside of Vitamin C

So, what’s the catch? Well, Vitamin C is unstable… meaning that it loses its power over time. “Vitamin C is an antioxidant, and a very reactive one. If it comes in contact with a free radical, it oxidizes and neutralizes the free radical in the process. Free radicals are present in our skin, but this reaction can also occur through exposure to air or UV light in the bottle, which ‘uses up’ the Vitamin C before it even is applied to our skin,” explains Doctor Anne. “Oxidized Vitamin C is not harmful applied to the skin, just useless.” Exposure to heat, light and air speeds up the degradation of the ingredient. You’ll know if your serum is ineffective once it’s darkened, usually turning yellow or orange.

It’s important to purchase a serum packaged to maintain its properties as well as store it properly so you get the most out of it. While some of my favorite serums come in dropper-style bottles, those actually oxidize the serum the quickest. Look for pump or squeeze style packaging that is dark or opaque. Smaller bottles are better when it comes to Vitamin C, as you’re more likely to use all of the product before it oxidizes. After using, make sure you close the lid tightly and keep in a dry, cool place. A skin care fridge is a perfect place for your Vitamin C serum! Otherwise, keep it outside of the bathroom (like on your nighstand) as the temperature and humidity from showers can make it break down quickly.

My Favorite Vitamin C Serums

The serum that showed me results quickly and got me hooked on Vitamin C was the Pixi Vitamin-C Serum ($24). I used it twice a day and started seeing results within a week and a half. My mind was blown! However, due to the dropper-style bottle, it oxidized quickly. There was probably a couple tablespoons of product left in the bottle when I tossed it due to the deep color change, signifying that it was no longer effective.

Next, I’d recommend the Derma E Vitamin C Concentrated Serum ($19.99). The formula also contains hyaluronic acid to rehydrate the skin as well as aloe and Vitamin E to moisturize and soothe. The pump bottle makes application easy and keeps the formula stable longer.

Finally, another serum I’ve used and love is the Vichy LiftActiv Vitamin C Brightening Skin Corrector ($28.50). It contains 15% pure Vitamin C plus hyaluronic acid, and is a fragrance-free formula that’s great for sensitive skin like mine. This one absorbs really quickly so it layers well with other products without feeling heavy. The bottle is small enough so that you can get through the entire thing before it oxidizes too much, despite the dropper bottle.
