What Is Vitamin C?
Vitamin C is a potent brightening antioxidant. The most researched form is L-ascorbic acid (pure vitamin C), highly effective but more active; gentler derivatives suit sensitive skin. You'll see it from around 10% up to 23% — beginners often start lower and build up. It's most effective applied in the morning, before SPF.

Vitamin C vs. Niacinamide
Both brighten, and they work beautifully together. Vitamin C is an antioxidant that boosts radiance and collagen; niacinamide fades dark spots, controls oil, and strengthens the barrier. Contrary to the old myth, they can be layered. Pair vitamin C with niacinamide for maximum brightening.

How to Use Vitamin C
Cleanse, tone on damp skin, apply a vitamin C serum in the morning, follow with moisturizer, and always finish with SPF — vitamin C and sunscreen are the ultimate morning duo. Start slow if you're new to it, and store vitamin C sealed and away from light to keep it potent.
Frequently Asked Questions
What does vitamin C do for your skin?

When should I apply vitamin C?
In the morning, before sunscreen — they work together to protect against UV and free-radical damage.

Is vitamin C good for dark spots?
Yes — it's one of the most effective ingredients for fading dark spots and hyperpigmentation over time.
Why did my vitamin C change color?
