Why You Need a Vitamin C Serum in Your Beauty Routine

It seems like everyone is trying to sell a health fad these days. You need vitamins for your nails, your hair, and wait… Vitamin C… for your face?! 

I was skeptical when I first heard about the Vitamin C serum craze. I eat oranges and drink EmergenC when I’m sick – doesn’t that provide me with all the Vitamin C my body needs?

Apparently not. 

Vitamin C is an antioxidant, a buzz word we are all familiar with, but what exactly are antioxidants? 

According to the Merriam-Webster Dictionary online, an antioxidant is “a substance (such as beta-carotene or vitamin C) that inhibits oxidation or reactions promoted by oxygen, peroxides, or free radicals.”

In plainer English this means antioxidants assist in protecting your cells and DNA from the damaging effects of free radicals. 

Free radicals are produced naturally in your body but it’s important to have a balance of free radicals and antioxidants. Too much of either is bad news.

So why put Vitamin C on your face?

UV rays, pollution and other environmental factors can contribute to signs of premature aging in your skin. 

Vitamin C serums help stimulate new cellular growth and the formation of collagen, which improves skin firmness, smoothness, and overall skin health. 

They can brighten and even out your skin tone. Vitamin C serums also assist with fading dark spots. 

They are truly a skin care essential!

Not all Vitamin C serums are created equal, however. 

Shopping for a serum

When shopping for a serum, it’s likely you’ll want to seek out Vitamin C in its purest form, L-ascorbic acid. 

If you have super sensitive skin, however, then you may want to opt for something a little less potent. 

Consider a formula with some of the other popular forms of Vitamin C: Magnesium Ascorbyl Phosphate, Sodium Asdorbyl Phosphate, and Ascorbyl Tetraisopalmitate. 

Packaging matters

You don’t want to just go out and buy a random Vitamin C serum.

Your serum should be packaged in an air-tight container because light exposure and oxidation will cause the product to expire faster. An amber-hue bottle with a pump is an ideal choice. 

When your Vitamin C serum changes color, texture, or smell, it’s no longer good for your skin. Don’t use an oxidized (aka expired) Vitamin C serum!

Top Rated Serums

These are the top rated Vitamin C serums at Sephora with L-ascorbic acid in them:



This is the serum I opted to purchase. It appealed to me because it’s cruelty-free, without fragrance, and was formulated by a dermatologist and cancer researcher.


Use your Vitamin C serum once a day, (morning is preferred, and be careful if the concentration of ascorbic acid is high- follow the instructions on the bottle) and don’t skip using your sunscreen afterward! They work together to protect your skin!
