Introduction

Vitamin C serum—by now, it’s likely a staple on every skincare enthusiast’s shelf. Loved for its brightening powers and anti-aging benefits, this potent antioxidant has earned its place in our routines.

It increases circulation, brightens skin, boosts collagen production, combats environmental stressors, and repairs surface damage.

Here’s the question we need to discuss right now: What is the ideal time to use a Vitamin C serum – day or night?

Given the popularity of Vitamin C serums in the skincare community, it’s been on everyone’s mind lately.

Besides, it is even recommended by experts for all skin types. Yes, for sensitive skin skin peeps too!

But there’s some debate on whether to use this potent serum in the morning or at night or both. Let’s delve deeper!

Day or Night The Best Time to Apply Vitamin C Serum

Vitamin C In The Morning

The light texture and fast-absorbing properties of Vitamin C serum make it ideal for morning-time applications.

It’s perfect for layering under moisturizer, makeup, and sunscreen.

Besides, when you apply the serum in the morning, it protects your skin from environmental stressors like UV rays and pollution throughout the day.

However, apply a broad-spectrum sunscreen with an SPF of 50 or higher to give your skin the best protection.

Sensitive skin peeps, looking for the best Vitamin C serum for your skin?

Don’t go for high-concentration Vitamin C serum during the day.

It’s best to opt for one with concentrations between 10% and 20%, like the CITTA Vitamin C Brightening Face Serum, which has 10% vitamin C and 2% Kakadu Plum, perfect for beginners and sensitive skin.

Vitamin C At Night

You can also soak in the benefits of Vitamin C at night.

Your skin is busy repairing itself while you snooze, and therefore, applying the serum as part of your nighttime routine ensures it gets absorbed effectively.

Additionally, you don’t have to worry about photosensitivity, which sometimes can happen with daytime use.

During the night, your skin is most receptive. Hence, using a Vitamin C serum can help boost collagen production, brighten your skin, and target hyperpigmentation.

Quick Tip:

Store your Vitamin C serum in a cool, dark place.

Exposure to light and air can oxidize Vitamin C, making it less effective.

Also, ensure your skin’s pH is balanced (after cleansing) to maximize absorption.

In a Nutshell: Benefits of Vitamin C Serum

1. Brightens Dull Skin

Vitamin C inhibits melanin production, which helps fade pigmentation, dark spots, and uneven skin tone—leaving your skin radiant and glowing.

2. Boosts Collagen Production

It stimulates collagen synthesis, helping to maintain skin’s firmness and elasticity while reducing the appearance of fine lines and wrinkles.

3. Fights Free Radicals

As a powerful antioxidant, Vitamin C protects the skin from oxidative stress caused by pollution, UV rays, and other environmental aggressors.

4. Speeds Up Skin Repair

It supports the skin’s natural healing process, making it effective for repairing sun damage and post-acne marks.

5. Improves Skin Texture

Regular use can smoothen rough patches and give your skin a soft, even texture.

6. Enhances Sunscreen Efficacy

When used in the morning, Vitamin C works synergistically with sunscreen to defend against sun damage more effectively.

7. Safe for Most Skin Types

When used in the right concentration (typically 10–20%), Vitamin C is well-tolerated and safe for oily, dry, combination, and even sensitive skin.

Final Thoughts… When To Use It?

Whether you use it in the morning or at night, a well-formulated Vitamin C serum for bright skin will give your face the glow you need.

Wish to apply it only during the day? Make sure to pair it with sunscreen for added protection against the harmful UV rays of the sun.

No matter when you choose to apply it, consistency is key. So, pick the time that suits your routine best and let Vitamin C do its magic.
