Niacinamide helps fade uneven skin tone by slowing melanin production, calming inflammation, and strengthening the skin barrier. With regular use, it visibly improves dark spots, post-acne marks, and blotchiness, without irritation or downtime.
Uneven skin tone is one of the most stubborn skincare concerns, whether it's from sun damage, hormonal changes, or post-acne marks. Niacinamide, a well-studied form of Vitamin B3, offers a low-irritation, high-reward approach to brightening and balancing your complexion.
At KarinaNYC, we've helped hundreds of clients achieve visible clarity using expert-curated routines built around actives like niacinamide.
If you're tired of products that promise a glow and deliver nothing, keep reading, because this guide will show you exactly how niacinamide works and how to use it right.
What Causes Uneven Skin Tone?
If you’ve ever looked in the mirror and noticed patches of darkness, dullness, or blotchy areas that weren’t there before, you’re not alone. Uneven skin tone is one of the usual concerns I see in clinic. And trust me, it doesn’t care how old you are or how much you’ve spent on skincare. It happens to everyone.
There are four main culprits I see over and over again:
Sun Damage And UV Exposure
Decades of unprotected sun exposure, even if it’s just walking the dog, leads to melanin clustering into little “sun spots” over time. It’s your skin’s way of trying to protect itself, but it leaves you with blotchy patches that deepen year after year.
Hormonal Shifts (Like Melasma)
Melasma often shows up as symmetrical blotches, especially around the cheeks and forehead. I’ve seen it triggered by birth control, pregnancy, or even stress.
It’s deeply rooted and tends to worsen with heat, UV, and inflammation, so it requires a delicate approach.
Post-Inflammatory Hyperpigmentation (PIH)
This is what happens after a breakout, rash, or even aggressive exfoliation. Once the skin calms down, it leaves behind a mark, usually pink, red, or brown depending on your skin tone.
- The good news? It’s very responsive to the right routine.
- The bad news? Many people make it worse by being too aggressive.
Aging And Glycation-Related Discoloration
As we age, the skin’s metabolism slows and the even glow we had in our twenties starts to fade. Yellowing, sallow tones, and brown patches can appear from years of sugar exposure (glycation), UV, and just...life.
It’s not your fault. But it can be helped.
Why Niacinamide Works So Well For Uneven Skin Tone
Niacinamide is a form of Vitamin B3, completely water-soluble, and gentle enough to use every single day. Don’t be fooled by its simplicity, this is one of the most versatile and effective ingredients we have in skincare.
What makes niacinamide so special is its stability.
It doesn’t oxidize like vitamin C, it doesn’t make your skin peel like retinol, and it doesn’t trigger the same sensitivity that acids can. It’s safe, powerful, and best of all? It works for everyone, even my clients with rosacea or ultra-reactive skin.
It’s like the Swiss Army knife of actives: brightening, soothing, and strengthening all in one.
How Niacinamide Targets Uneven Tone
Here’s why we use niacinamide so often in our practice at KarinaNYC, it goes after uneven tone from multiple angles, which is exactly what most people need. Pigmentation isn’t just about melanin. It’s about inflammation, barrier breakdown, oil imbalance, and healing capacity. Niacinamide touches all of those.
Inhibits Melanin Transfer To Skin Cells
Niacinamide doesn’t bleach or peel the skin, it works by interrupting the process where pigment moves from deep in the skin to the surface. This helps fade dark spots gradually and safely.
Strengthens Your Barrier
Uneven tone isn’t just about pigment, it’s often tied to a weak, compromised skin barrier. Niacinamide boosts ceramide production, which means better hydration and less inflammation overall. And less inflammation = less pigment.
Brightens Dull, Tired-Looking Skin
Pigment makes skin look muddy. Niacinamide works to restore clarity and luminosity by reducing redness, calming blotchiness, and supporting overall skin clarity.
Reduces Inflammation That Worsens Discoloration
I’ve seen this time and time again, when clients use too many actives, the skin becomes inflamed and the pigmentation gets worse. Niacinamide calms the fire. It’s a reset button for stressed skin.
Regulates Sebum And Reduces PIH From Acne
For those dealing with breakouts and the marks they leave behind, niacinamide is gold. It helps balance oil production, which means fewer breakouts, and less post-inflammatory pigmentation from acne that’s healing.
Want Bright, Even Skin? Here’s How I Use Niacinamide
When to Apply It
The beauty of niacinamide is that it’s a team player. It doesn’t require special timing or delicate handling. You can use it morning, night, or both, whatever fits your lifestyle.
And unlike some actives, it won’t make your skin photosensitive, so it’s perfectly safe in the sun (just don’t forget your SPF, of course).
Personally, I love it in the morning to help with oil control and barrier support, and again at night layered with actives like retinol or peptides. It’s one of those ingredients that just makes everything else in your routine work better.
What Products To Use (Serum, Toner, Moisturizer)
There’s no one-size-fits-all here, and that’s the beauty of niacinamide, it shows up in multiple product formats. Here’s how I think about each one when designing a routine for a client:
Serums
This is your heavy hitter. If pigmentation is your #1 concern, start with a niacinamide serum, ideally around 5%. It’s targeted, potent, and absorbs quickly. I often recommend these right after cleansing and before other treatment products.
Toners
People sleep on toners, but they’re incredibly valuable, especially when they’re packed with niacinamide, hydrating agents like Vitamin B5, or even calming botanicals like honeybush (which we use in our KarinaNYC PIGM prep toners).
Think of this step as setting the stage for everything else to absorb beautifully.
Lightweight Moisturizers
If you’re using other actives and just want niacinamide in the background doing its thing, a cream can be perfect.
Look for one with a blend of niacinamide, antioxidants, and barrier-repair ingredients for ongoing tone correction with zero drama.
Key Pairings That Boost Its Effect
One of the best things about niacinamide is how well it pairs with other actives. Done right, it can amplify results without overloading the skin.
Vitamin C
Brightening duo of dreams. Vitamin C tackles pigment from one pathway (tyrosinase inhibition), while niacinamide blocks melanin transfer. Together, they hit two major points of pigmentation formation, perfect for dull, sun-damaged skin.
Retinol
A power move for those with post-acne marks or aging concerns. Retinol accelerates cell turnover, while niacinamide calms inflammation and reinforces the barrier so you can actually tolerate the retinol long enough to see results.
Arbutin + Kojic Acid
Gentle melanin disruptors that complement niacinamide beautifully. We use this combo in more advanced pigmentation protocols when melasma or deep discoloration is at play.
Hyaluronic Acid
If your skin is dry, pairing niacinamide with hyaluronic acid is a hydration dream. Bonus: niacinamide helps lock in moisture by strengthening the skin’s lipid barrier.
Azelaic Acid
One of my favorite combos for rosacea-prone or sensitive skin types. Azelaic soothes and lightly exfoliates while niacinamide works on tone and barrier function.
Real Talk: Niacinamide Isn’t Tricky (If You Do It Right)
Niacinamide isn’t nearly as complicated as the internet makes it seem. The trick is knowing when to use it, what to pair it with, and how to avoid the layering mistakes that trigger redness or breakouts.
Here’s how to get clear, even-toned skin, without trial and error.
How Long Until I See Results?
On average, most of my clients notice visible improvement in uneven tone and dark spots within 4–8 weeks, sometimes faster if we’ve paired it with exfoliation or light therapy. It’s not an overnight miracle, but it is a consistent builder.
Should I Apply Before Or After Actives?
Always apply niacinamide early in your routine, right after cleansing and toning. Water-based serums go first, followed by oils or thicker creams.
If you're layering it with retinol or vitamin C, make sure the formulas are compatible and your skin barrier is in a good place.
Why Does My Skin Get Red When I Use It?
If you’re experiencing flushing or warmth, it’s likely not the niacinamide itself, it’s what you’re layering with it. Combining too many strong actives (like AHAs or retinol) can create irritation.
Simplify your routine and space out your layers. Your skin will thank you.
Can Niacinamide Make Your Skin Purge?
Technically, niacinamide isn’t an exfoliant, so it shouldn’t cause purging. But if you’re using it with actives like retinol or acids, it might speed up cell turnover just enough to unearth congestion.
Go slow. Introduce one new product at a time.
Is It Okay To Use With Vitamin C Or Retinol?
Yes, absolutely. Modern formulations are designed to work together, and I’ve seen incredible results when pairing niacinamide with both. Just be mindful of your skin’s tolerance, especially if you’re new to actives.
Top 5 BR Products For Uneven Skin And Dullness
Not all niacinamide products are created equal. What matters is not just the percentage of niacinamide; but how it’s formulated, what it’s paired with, and whether it fits your skin’s current needs.
These five Biologique Recherche (BR) picks have become go-to’s in our studio, not because they promise miracles, but because they’re beautifully designed to support real, visible change over time.
Sérum PIGM 400
This is a brilliant serum for clients focused on tone irregularities without wanting to overwhelm their skin. It blends niacinamide with a cocktail of botanical extracts that support brightness and antioxidant defense.
I often recommend this one post-travel, post-summer, or when your skin just looks tired. It layers seamlessly under other treatments and never pills, an underrated bonus.
Lotion P50 PIGM 400
This is our P50 formula specifically designed for pigmentation concerns, and it plays beautifully with niacinamide. It gently exfoliates while also hydrating and balancing the skin, giving niacinamide the perfect environment to do its job.
When clients want smoother texture and more clarity, this is the toner I reach for.
Creme PIGM 400
Lightweight, elegant, and effective. This moisturizer is ideal for daytime wear, especially under makeup. It supports pigment correction while keeping the skin comfortably hydrated.
I’ve seen great results when used consistently after brightening serums or post-P50. It gives your skin a polished finish that doesn’t feel heavy or greasy.
Masque VIP O2
This is a treatment mask I personally use before events or when my skin looks dull. With oxygenating actives and niacinamide, it’s a fast track to brighter, more radiant skin.
Clients often notice a difference after just one use, not just in tone, but in glow. It's especially lovely after a flight or late night.
Fluide VIP O2
Think of this as a city skin serum, perfect if you’re exposed to pollution, stress, or harsh weather. It protects, hydrates, and subtly evens the complexion with continued use.
I love it for clients who deal with reactive skin or redness. Niacinamide in this formula helps take the edge off stressed skin, while boosting tone over time.

I see it all the time, clients walking through our doors frustrated, after spending thousands on skincare that didn’t deliver. Not because their skin is “difficult,” but because most routines are too generic, too harsh, or too inconsistent to create lasting change.
