How to Layer Niacinamide and Vitamin C the Right Way

If you've heard that Vitamin C and Niacinamide can't be used together — that's outdated advice. Modern dermatology confirms they're safe and effective when layered properly.

In this guide, we'll show you exactly how to combine ROI's 15% Vitamin C Serum and Niacinamide Serum to get glowing, balanced, and happy skin.

Why Layer These Two Serums?

They do different things — and work beautifully when paired, especially for Indian skin dealing with pollution and humidity.

Vitamin C: Brightens dull skin, fades dark spots, and protects against pollution and environmental damage

Niacinamide: Reduces acne, controls oil production, calms redness, and strengthens skin barrier

Together, they help you glow — without irritation. Want to know more about their individual benefits? Check out our Niacinamide vs Vitamin C comparison guide.

2 Safe Ways to Layer

✅ Option 1: Split by Time of Day (Best for Beginners)

AM routine:

Cleanser
Vitamin C Serum
Moisturizer
Sunscreen

PM routine:

Cleanser
Niacinamide Serum
Moisturizer

👉 Great for sensitive skin or first-time users. This method ensures maximum effectiveness without any risk of interaction.

✅ Option 2: Layer in One Routine (For Experienced Users)

Use both serums in the same routine — but with a small wait time to ensure proper absorption.

Step 1: Cleanse your skin thoroughly
Step 2: Apply Vitamin C Serum (thinner consistency goes first)
Step 3: Wait 10–15 minutes for full absorption
Step 4: Apply Niacinamide Serum
Step 5: Finish with moisturizer (and SPF in the morning)

Can You Use Them Daily?

Yes — but follow these guidelines:

Introduce one serum at a time if you're new to actives
Use gentle formulas like ROI's with no added fragrance or harsh ingredients
Always wear sunscreen if you use Vitamin C during the day
Start with every other day and build up to daily use
