You probably already know that vitamin C is an essential part of a healthy diet. Your daily dose can help boost your immunity and offers a number of other benefits for your overall health.

Topical vitamin C serum is also great for your skin. Read on to find out why, plus learn about some of the best serums you can buy.

To understand how vitamin C works, you first have to understand free radicals. These natural molecules aren’t bad on their own, but they can become a problem when they build up. In high numbers, they can break cells down over time, contributing to illness and aging.

Antioxidants help fight free radicals, though, keeping everything in balance. Vitamin C is one such antioxidant. When used on the skin, it can combat signs of aging. It decreases hyperpigmentation, evens out your skin tone, reduces wrinkles, and protects your skin from sun damage.

If you’re interested in trying vitamin C serum but aren’t sure how to pick one, don’t worry! We rounded up 10 great options for you.

In selecting our top vitamin C serums picks, we looked at price, customer reviews, potency, and packaging. Vitamin C serum should be packaged in opaque packaging. Otherwise, it can break down when exposed to light, causing it to be less effective.

It’s worth keeping in mind that there are different types of vitamin C, and not all of them are equally effective.

We mostly chose products made with L-ascorbic acid, ascorbyl palmitate, tetrahexyldecyl ascorbate, and magnesium ascorbyl phosphate. We also kept an eye out for products that have additional beneficial ingredients.

Key ingredients: vitamin C, pumpkin ferment, pomegranate extract
Skin type: all skin types

Why we love it: A vitamin C formula that’s cruelty-free, free of essential oils, *and* has a fun name — what’s not to love? This Drunk Elephant formula is designed to stay on your skin for 72 hours.

When shopping for a vitamin C serum, it’s important to look for a product made of a potent, stable type of vitamin C. Look for L-ascorbic acid, ascorbyl palmitate, tetrahexyldecyl ascorbate, or magnesium ascorbyl phosphate on the ingredients list. It’s also best to look for a product that’s sold in opaque packaging, as vitamin C can break down when exposed to sunlight.

You can also check out the other ingredients, especially if you’re looking to help several skin concerns at once. For example, hyaluronic acid or glycerin are good additions for dry skin, while AHAs can help slough off dead skin. Some products may also be formulated with retinol to help eliminate the appearance of wrinkles.

Many products are made with 10 to 20 percent vitamin C, and that’s usually potent enough. Older studies show that maximum absorption is achieved at 20 percent.

In general, it’s best to cleanse and tone before applying your vitamin C serum. Then follow with a moisturizer.

You’ll only need a few drops of serum, which you should gently pat into your skin with your fingertips. You can use the serum once or twice per day.

Adding a vitamin C serum to your daily routine will improve your skin’s glow while reducing the damaging effects of the environment and the sun. The longer you use a vitamin C serum consistently, the more you’ll be able to see the difference it makes.

As always, discontinue use if the product irritates your skin.
