Vitamin C is one of the most loved and proven skincare ingredients in the world — and for good reason. A good vitamin C serum brightens, evens tone, fades dark spots and gives that healthy glow. Here’s how to choose and use one, from Z & Z Cosmetics.
Benefits of vitamin C
- Brightens dull, tired skin for a radiant glow.
- Fades dark spots and evens out skin tone.
- Antioxidant protection — defends against pollution and sun damage.
- Boosts collagen — helps firm skin and soften fine lines.
How to use vitamin C serum
- Use it in the morning, on clean skin, before moisturiser.
- Apply a few drops and pat gently into the face and neck.
- Always follow with sunscreen — vitamin C + SPF is a power duo against dark spots.
- Start every other day if you’re new to it, then build up.
How to choose the right one
- Concentration: 10–15% suits most people; start lower if sensitive.
- Packaging: dark or airless bottles keep vitamin C fresh and effective.
- Pair well: vitamin C loves niacinamide, hyaluronic acid and SPF.
- If a serum smells off or turns dark brown, it has oxidised — replace it.
Prefer a cream or mask?
Not everyone loves serums — you can also get vitamin C benefits from products like the Celimax Pore + Dark Spot Brightening Cream or a weekly Vitamin C sheet mask. Explore options in our Skincare Products collection.

Common vitamin C mistakes to avoid
- Skipping sunscreen — vitamin C works best paired with SPF.
- Using an oxidised serum — if it turns dark/brown, it’s no longer effective.
- Layering with strong actives — avoid using with strong AHAs/retinol at the same time.
- Starting too strong — build up slowly if you have sensitive skin.
FAQs
Morning or night? Morning is ideal, for daytime antioxidant protection.
Can all skin types use it? Yes — sensitive skin should start with a lower concentration.
