When it comes to brightening and protecting your skin, Niacinamide and Vitamin C are two of the most celebrated ingredients in modern skincare. But if you’ve ever browsed beauty forums or TikTok, you’ve probably come across the debate: Can these two powerhouse actives be used together—or do they cancel each other out?
Let’s uncover the science, the myths, and what it means for your daily routine.
What Is Niacinamide?
-
Also known as: Vitamin B3
-
Skin benefits:
-
Strengthens the skin barrier
-
Reduces redness and blotchiness
-
Balances oil production
-
Minimizes the look of pores
-
Supports collagen production over time
-
Niacinamide is gentle, versatile, and well tolerated by almost all skin types. It’s a true multitasker that makes other actives in your routine work better.
What Is Vitamin C?
-
Also known as: L-Ascorbic Acid (and its derivatives)
-
Skin benefits:
-
Potent antioxidant that shields skin from free radical damage
-
Boosts collagen synthesis for firmer skin
-
Brightens hyperpigmentation and uneven tone
-
Enhances sunscreen protection
-
Vitamin C is highly effective, but can sometimes feel unstable or irritating in high concentrations.
The Myth: Niacinamide and Vitamin C Don’t Mix
For years, the internet has claimed that combining Niacinamide and Vitamin C makes them “inactive” or could irritate the skin. This myth comes from old, outdated research where high heat caused a reaction between the two.
In real-world skincare formulations, however, modern science shows that these two actives can absolutely coexist—and even enhance each other’s benefits.
The Science: Why They Work Together
-
Stability: Modern formulations stabilize Vitamin C with pH adjustments and encapsulation, making it safe to pair with Niacinamide.
-
Synergy: Vitamin C neutralizes free radicals on the skin’s surface, while Niacinamide works deeper to repair and calm. Together, they deliver a brighter, more even complexion.
-
Skin tolerance: When layered properly, the combination reduces irritation compared to using Vitamin C alone.
How to Use Them in Your Routine
-
Layering order matters:
-
Apply Vitamin C first (usually in the morning, before sunscreen).
-
Follow with Niacinamide serum or moisturizer.
-
-
Patch test first: Sensitive skin may prefer using Vitamin C in the AM and Niacinamide in the PM.
-
Don’t forget SPF: Both ingredients are most effective when paired with daily sun protection.
Halal Perspective: Is It Safe & Permissible?
-
Niacinamide is a synthetic form of Vitamin B3, not derived from animals—making it halal-friendly.
-
Vitamin C used in skincare is either synthetic or plant-derived, which is also halal-compliant.
-
At Purelab Care, we ensure that every formulation avoids hidden animal derivatives and undergoes third-party testing for ingredient integrity.
