Vitamin C Serum: Your Brightening, Collagen-Boosting Glow Staple
Hello, beautiful people! Today we’re talking about a skincare hero many routines swear by: Vitamin C serum. If you’ve been wondering what it is and why everyone’s obsessed—good news: the hype is well-deserved. This antioxidant powerhouse can help bring back radiance, support firmer-looking skin, and improve the look of uneven tone over time.
Whether you’re new to actives or you’re building a more advanced routine, here’s everything you need to know: benefits, how to use it, storage tips, and quick FAQs.
What is Vitamin C serum?
Vitamin C serum is a skincare product formulated with Vitamin C—a potent antioxidant your skin loves. In skincare, Vitamin C is often listed as L-ascorbic acid (though there are other gentler derivatives too). The goal is simple: deliver a concentrated dose of antioxidant protection and brightening support to the skin.
Vitamin C isn’t one-size-fits-all. It comes in different strengths and formats, so whether you have dry, oily, sensitive, or combination skin, there’s a Vitamin C option that can work for you.
The benefits of incorporating Vitamin C serum into your beauty regimen
If there’s one ingredient that earns “skincare staple” status, it’s Vitamin C. With regular use, it can help:
- Brighten dull skin: supports a healthier-looking, more radiant glow
- Fade the look of dark spots: helps improve the appearance of hyperpigmentation and uneven tone
- Reduce the look of fine lines: supports smoother-looking skin over time
- Protect against environmental stress: helps defend against free radicals from pollution and daily exposure
- Support collagen production: helps skin look firmer and more elastic
- Support sun-damage prevention: adds antioxidant backup alongside daily sunscreen
COSRX The Vitamin C 23 Serum is a popular choice for those wanting a high-strength brightening boost.

Using Vitamin C serum is simpler than it sounds. Most people prefer it in the morning to maximise antioxidant support during the day.
- Cleanse
- Tone (optional)
- Vitamin C serum (2–4 drops, pat in)
- Moisturiser
- Sunscreen (non-negotiable)
Consistency is key. For visible improvement, use it regularly and always pair it with daily SPF. And as with any active: patch test first.
Tips on how to use your Vitamin C correctly
A few drops are enough. Using more than recommended won’t speed up results—it may just increase irritation risk.
Vitamin C works best when it can absorb properly—apply after cleansing (and toner if you use one).
Wait a minute or two before layering moisturiser and SPF so the serum can sink in fully.
Where to store your Vitamin C
Vitamin C is sensitive to light, heat, and air, which can cause it to oxidise and lose effectiveness. Store your serum in a cool, dark place (not the bathroom), and always close the bottle tightly after use.
If your Vitamin C turns significantly darker or smells “off,” it may have oxidised—consider replacing it for best results.
FAQs
A: Yes, especially for sensitive skin or higher-strength formulas. Patch test first and start slowly if you’re new to actives.
A: Yes. Vitamin C can help support skin recovery and calm the look of inflammation. If you’re actively breaking out, choose a gentle formula.
A: It varies, but many people start noticing improvements after about 2–3 weeks of consistent use.
