How to Use Vitamin C Serum

Vitamin C serums are one of the best skincare products for anti-aging, fading dark spots, firming skin, reducing hyperpigmentation, and more. But you have to know how to use a vitamin C serum. Vitamin C is a powerful antioxidant that can benefit your skin by:

  • Reducing the look of wrinkles by boosting collagen in your skin
  • Fading dark spots and hyperpigmentation
  • Adding glow to your skin
  • Firming crepey skin
  • Undoing sun damage

Amazing, right? However, actually making sure that Vitamin C is able to benefit your skin in all these different ways starts with using a Vitamin C serum the right way. 

How To Use Vitamin C Serum?

Vitamin C serums require a little bit of knowledge to be used properly so your skin can get all the benefits. Using Vitamin C Serum at the right time, for example, can make a huge difference to ensure your skin gets all the perks of this potent skincare ingredient.

When to Use Vitamin C Serum?

Vitamin C is best applied to your skin in the morning. 


Using your Vitamin C serum in the morning has two important benefits for your skin. First, your skin actually gets a small amount of protection from oxidants (aka ‘free radicals’) you might be exposed to during the day - free radicals can be caused by sunlight, pollution, and smoking. 

Giving your skin daily protection from these harmful particles prevents issues such as the skin losing firmness, dullness, as well as dark spots and hyperpigmentation - especially if you use a daily sunscreen, too!

Another reason to use your Vitamin C serum in the morning is that it leaves your nighttime routine free to use other amazing skincare ingredients, such as Retinol or exfoliating acids. 

Unlike Vitamin C, these skincare ingredients can make your skin more sensitive to the sun right after use - so it’s best to apply them at nighttime instead.

Tips for Using Vitamin C Serum

Another really important thing about Vitamin C serum is its pH. Vitamin C has a slightly acidic pH and needs to stay at this pH under 4 for best results on your skin.  

Applying your Vitamin C serum to skin that’s still damp from water or your toner can raise its pH, which can make your Vitamin C serum less effective.

The solution?

Always apply your Vitamin C serum to clean, dry skin. This will give you the amazing results of firmer skin, a more radiant glow, and quickly fade those pesky dark spots!


So pick a Vitamin C serum with a pH of under 4. And add it to your morning routine every day.
