What Is Vitamin C Serum?

A vitamin C serum is a lightweight, concentrated skincare product packed with vitamin C, a powerful antioxidant. It helps your skin fight free radicals (the unstable molecules from pollution, UV rays, and stress that damage skin cells), while also supporting collagen production. As a result, it is one of the most effective ways to fade and reduce dark spots and get a glow from within.

What does vitamin C do for your skin?

Vitamin C isn't just a brightening ingredient. It's multifunctional. Here are some of its benefits.

It gives you a glowing, blemish-free skin.
It reduces dullness and fades dark spots.
It supports collagen production, keeping skin firm and youthful.
It evens skin tone, making it look smoother and more radiant.

When to Use Vitamin C Serum?

You can apply a vitamin C serum twice a day, in your morning and night routine.
Applying vitamin C in the morning helps protect skin from daily exposure to UV rays and pollution.
Always follow up with sunscreen; vitamin C boosts its effectiveness.

For the night routine

Applying vitamin C serum at night can help repair skin while you sleep.
It is also recommended to apply a vitamin C serum at night, as it helps target pigmentation, acne marks, and dullness while you sleep.

The Best Way To Use And Store Vitamin C Serum For Maximum Effectiveness

Vitamin C oxidizes with light. Therefore, store it in a cool, dark place.
Use a stable form, like L-ascorbic acid.
Always follow it up with a sunscreen in the morning.
Avoid layering your vitamin C serum with any exfoliating acids or retinol in the same routine.

Pat it in: Gently pat the serum into the skin; do not massage.
Pairing with other actives: Avoid pairing it with strong active ingredients, like retinol or salicylic acid serum, in the same routine.
