Vitamin C serum is known for its brightening, anti-aging, and antioxidant properties, making it a staple in many skincare routines. While it’s often recommended for daytime use because of its protective benefits, using Vitamin C serum at night can also be highly effective for skin repair and rejuvenation.

In this blog, we’ll guide you through the proper steps to use Vitamin C serum on your face at night to get the most out of this powerful skincare ingredient.

Why Use Vitamin C Serum at Night?

At night, your skin goes into repair mode—healing damage caused by sun exposure, pollution, and daily stress. Applying Vitamin C serum before bed can help accelerate this repair process by:

• Boosting collagen production

• Reducing signs of aging like fine lines and wrinkles

• Fading dark spots and hyperpigmentation

• Protecting skin from free radical damage

Step-by-Step Guide: How to Use Vitamin C Serum on Face at Night

1. Cleanse Your Face

Start by washing your face with a gentle cleanser to remove dirt, makeup, and impurities. Clean skin allows the serum to penetrate better. If you want to learn about the best cleansers for your skin type, read our guide to choosing the right cleanser (internal link).

2. Apply Toner (Optional)

If you use a toner, apply it after cleansing to balance your skin’s pH and prepare it for better absorption of the serum.

3. Apply Vitamin C Serum

Take 2–3 drops of Vitamin C serum on your fingertips and gently pat it onto your face and neck. Avoid rubbing harshly; gentle tapping helps the serum absorb faster.

4. Let It Absorb

Wait for about 1–2 minutes to allow the serum to fully absorb into your skin before moving on to the next step.

5. Apply Moisturizer

Seal in the serum with a nourishing moisturizer to hydrate your skin overnight. For recommendations, see our top moisturizers for nighttime skincare (internal link).

Tips for Using Vitamin C Serum at Night

• Start Slow: If you’re new to Vitamin C serum, begin by using it every other night to see how your skin reacts.

• Check the Concentration: Higher concentrations (above 15%) might cause irritation at night; opt for milder formulas if you have sensitive skin.

• Avoid Mixing with Retinol Immediately: Vitamin C and retinol are both potent. To avoid irritation, use Vitamin C serum at night and retinol on alternate nights or in different routines.

• Store Properly: Keep your serum in a cool, dark place to maintain its effectiveness.
