Niacinamide and Vitamin C, you are sure to find these glow givers all over the skincare aisle. From masks to cleaners to heavy-duty serums – just name it. The two active ingredients diminish the appearance of spots and pigmentation, though via different pathways. So, naturally, the question comes to mind: Can you pair Vitamin C and Niacinamide to reap maximum benefits for your skin? 

The debate around Vitamin C vs Niacinamide has evolved—what was once seen as a skincare clash is now a power combo in 2025. Fast forward to 2025, and the verdict is clear: what was once believed to be a skincare standoff is now recognised as a powerhouse combination. 

Let’s break down the myths, science, and modern usage to help you decide how to get the most out of your niacinamide serum and vitamin C. 

Understanding The Basics 

To make the most of Vitamin C and Niacinamide in your routine, a basic refresher on the ingredients is necessary

Vitamin C: While the water-soluble ingredient is famously known for its brightening properties, it works on several other concerns. It is a potent antioxidant that keeps menacing aggressors at bay, boosts Collagen production to soften ageing lines, and soothes inflammation and irritation.

Niacinamide: This Vitamin B3 derivative is a multitasker in every right that works across skin types. Apart from administering an even skin tone, topical application of Niacinamide serum hydrates the skin, curbs sebum production, boosts barrier health, and calms irritation.  

From Skincare Rivals to Radiance Duo

Once believed to clash due to potential pH conflicts, vitamin C and niacinamide are now known to work harmoniously when properly formulated. Recent advancements in skincare chemistry have proven that pairing them can lead to brighter, calmer, and more resilient skin.

So if you’re still asking “Can I use vitamin C serum and niacinamide together?” the answer is yes—with glowing results. 

Why Niacinamide Complements Vitamin C ? 

While Vitamin C is a perfectly safe active it may cause inexplicable irritation and skin flare-ups, in rare cases. This is where Niacinamide comes into the picture. Its anti-inflammatory properties help alleviate the skin while preserving hydration and boosting barrier health.

Key Benefits of Combining Niacinamide and Vitamin C

Wondering why you should combine them? Here’s what they can do together:

• Brighter Skin: Vitamin C fades pigmentation and niacinamide enhances radiance

• Stronger Barrier: Niacinamide reduces inflammation and helps your skin retain moisture

• Even Tone & Texture: Vitamin C smooths skin, while niacinamide shrinks pores

• Balanced Oil Production: Niacinamide regulates sebum, reducing breakouts

In short, the benefits of combining niacinamide and vitamin C go beyond what each ingredient can do alone.

How to Layer Vitamin C and Niacinamide

Mastering the art of layering these two actives is easier than you think.

• Morning Routine:  Start with a low pH Vitamin C serum and follow up with a neutral Niacinamide essence to maximise absorption & to protect against free radicals and brighten.

• Choosing pH levels: Vitamin C works best in an acidic pH, approximately 3.5. It seeps deep into the skin for better results. Niacinamide, on the other hand, works well in neutral to slightly acidic pH (around 5 to 7).

• Finish with SPF: Always follow with sunscreen to protect and lock in benefit

Still unsure when to use niacinamide and vitamin C? Keep vitamin C in your AM routine and niacinamide in either AM or PM, depending on your skin’s needs.

When And Why Niacinamide And Vitamin C Can Clash? 

As discussed earlier, Niacinamide and Vitamin C are actives that bring out the best in each other – on most occasions. However, in rare cases, these brightening agents may clash due to -

1. Using high concentrations of the two actives: If you are using high concentrations of both Niacinamide and Vitamin C, you are likely to experience redness, inflammation, and other flare-ups.

2. Layering incorrectly: Layering right is directly proportional to the efficacy of active ingredients. So, if you are slathering Niacinamide and Vitamin C back-to-back, you are bound to face some discomfort on the skin.

If you're worried about nighttime irritation or want to add more barrier-supportive ingredients, using a retinol-based night cream like the Revitalising Night Cream with Sea Buckthorn, Acai Berry & Retinol can help balance and nourish your skin overnight. Its antioxidant-rich formula complements your morning brightening routine without overloading your skin.

- Combat oily skin: Niacinamide curbs sebum production, and Vitamin C prevents clogged pores.

- Revive dry skin: Both Niacinamide and Vitamin C ensure long-lasting moisturization of the skin, banishing dry and flaky texture

- Soothe inflamed skin: Packed with anti-inflammatory properties, the pair helps alleviate flare-ups
