The Best Vitamin C Serums for the Face

One powerhouse ingredient you should certainly consider adding to your skincare arsenal is vitamin C, also known as L-ascorbic acid (or ascorbate). This strong antioxidant is a must for maintaining healthy skin and overall well-being. And what better way to introduce it into your routine than with a vitamin C serum? Thanks to their higher concentration of active ingredients, serums offer a powerful way to deliver this nutrient directly to your skin. Because we all know the importance of getting our daily dose of vitamins.

Finding the best vitamin C serum for your face can be a bit of a challenge. But don’t worry—we’ve got you covered. At Cosmetify HQ, when it comes to diving deep into the world of skincare to bring you the crème de la crème, you can count on us.

How Does Vitamin C Work?

If you have yet to know, get to know - Vitamin C is one of the most renowned ingredients in the skincare game. It’s a particular subgenre of ingredient that’s otherwise known as an antioxidant: it works by neutralising free radicals—unstable molecules that come from things like UV exposure and pollution. Free radicals can cause serious damage to your skin, leading to premature ageing. Vitamin C steps in to protect your skin, helping to prevent fine lines, wrinkles and more. If you still have yet to be convinced, Vitamin C is also a key player in collagen production, which is essential for keeping your skin firm and bouncy. By boosting collagen levels, it helps to improve skin elasticity and reduce sagging, giving your face a more lifted and youthful look.

How To Find The Best Serum

When on the hunt for the best vitamin C serum for your face, there are a few things to consider. First, pay attention to the concentration of vitamin C in the formula. Anything above 20% might cause irritation, especially if you have sensitive skin. While vitamin C is generally safe for daily use, if you experience any discomfort, start by applying it once or twice a week. Or, you can mix a few drops into your moisturiser to help your skin adjust.

FAQs About Vitamin C Serums

What does vitamin C do for your skin?
Vitamin C is a potent antioxidant that protects against free-radical damage from pollution and UV exposure. It helps brighten the complexion, fade dark spots and stimulate collagen production for firmer, smoother skin. Discover more glow-boosting options in our vitamin C skincare collection. It pairs wonderfully with niacinamide, which you can read more about in our blog post 'Can You Use Niacinamide With Vitamin C?'

How do you use a vitamin C serum?
Apply your serum to clean, dry skin each morning before moisturiser and SPF. Use a few drops and gently press into the face and neck. If your skin is new to vitamin C, start every other day, then increase frequency once your complexion adjusts.

Can you use vitamin C serum every day?
Yes — most people can use vitamin C serum daily. It’s best applied in the morning to help shield skin from environmental stressors, but you can also use it at night alongside hydrating or repairing products.

What should you not mix with vitamin C serum?
Avoid layering it with high-strength retinol or AHAs/BHAs at the same time, as this may cause irritation. Instead, alternate usage (vitamin C in the morning, retinol at night) and always finish with sunscreen during the day.

Which vitamin C serum is best for your skin type?
• Dry skin: try dual-action or oil-based formulas like Pestle & Mortar Vitamin C 2 Phase Serum.
• Sensitive skin: gentle, plant-based options such as Antipodes Glow Ritual Serum.
• Oily/normal skin: lightweight, fast-absorbing choices like Eucerin Hyaluron-Filler Vitamin C Booster.
