Steps range from washing to exfoliating to moisturizing. But today, we’re going to be looking into one step in particular: serums. Specifically, vitamin C serums and how they are a great addition to your skincare routine!

Today we’re going to be diving into everything vitamin C serum, including:

  • What is a vitamin C serum?
  • How do you use it?
  • How do they work?
  • And what are the best K beauty vitamin C serums?

What is a Vitamin C Serum?

Vitamin C serum is exactly what you’d think! It’s a serum, typically a gel or liquid formula, that is rich with vitamin C. This means that it contains tons of great antioxidants for your skin. When you see words like “firming,” “brightening,” and “collagen boosting,” it really just means that the product will give you that luminous, youthful skin you’ve been looking for! 

Vitamin C serums can be implemented seamlessly into your skin care routine!

How to Use Vitamin C Serums

Vitamin C serums are applied topically to your skin. According to the K-beauty ten step routine, it should be applied after cleansing and toning your skin, but before using thicker products like moisturizer and sunscreen. You should use somewhere between one and three drops of serum, and only apply once or twice per day. So, as long as you’re applying once in the morning and once before you head to bed (basically when you do your usual skin-care routine), you’ll be set!

How Do Vitamin C Serums Work?

Okay, so you know what a vitamin c serum is and how to use it, but why should you be implementing this serum into your daily routine? Well, the simple answer is that vitamin C serums brighten and even your skin. They have your skin looking dewy and youthful in the blink of an eye. But how does it do that? 

These serums boost the collagen in your skin, which is a naturally occurring protein that keeps your skin from sagging. As we age, our bodies produce less collagen and therefore sag more. Vitamin C serums encourage more collagen production and maintain the collagen that is already in your skin. That’s how it keeps you looking young!
