Niacinamide is a form of vitamin B which supports your skin’s barrier repair, regulates oil, improves uneven tone, and offers hydration, making it a crowd favourite in moisturizers, serums, and even cleansers.
Yet this popularity does not mean it comes without caution. A question that pops up a lot is can niacinamide moisturizer cause dryness if overused, especially in winter? This question becomes more relevant as winter air stresses your skin barrier.
If you’re wondering whether to switch products altogether, check out Should You Change Your Niacinamide Moisturizer in Winter? — it breaks down how climate and formulation type affect niacinamide performance.
In this blog, we will explore what role niacinamide plays in maintaining your skin’s hydration, how to use niacinamide moisturizer correctly to avoid dryness during winter while maintaining skin balance and understand niacinamide overuse effects.

Understanding Niacinamide’s Role in Skin Hydration
Niacinamide contributes to skin hydration mainly by boosting ceramide synthesis, reducing transepidermal water loss (TEWL), and reinforcing lipid layers. These actions help reduce niacinamide moisturizer dryness when used properly.
A clinical study by Piotr Zalecki shows topical niacinamide use resulted in increased skin hydration and improved skin tone over three weeks.
Because of this, niacinamide is often seen as a “gentle” active that pairs well in daily routines. But gentle does not mean it’s immune to misuse, which is why niacinamide in winter skincare must be handled with extra care to prevent barrier strain and dryness.
-
For general hydration, consider using niacinamide with 2–5% concentration levels.
-
The effect of niacinamide can differ depending on the climate you live in. In humid zones, niacinamide’s humectant effect is supported better, while in dry zones it relies on barrier reinforcement to retain moisture.
Why Overusing Niacinamide Can Lead to Dryness
'Overuse' can mean different things: using a very high concentration, layering multiple products with niacinamide, or applying it too frequently. These habits heighten niacinamide overuse effects and significantly increase the risk of niacinamide moisturizer dryness.
Niacinamide helps regulate oil production in your skin, which is extremely beneficial when used in moderation. When overused, it can reduce the natural oil production and can leave the skin feeling tight, flaky and dry.
Niacinamide overuse effects are real and must be paid attention to, particularly in seasons when your barrier is already vulnerable.
Winter Skin Challenges
During winter, the cold air and low humidity pull moisture out of your skin. The lipids in the skin barrier, which are usually soft and flexible, start to become more rigid in cold temperatures. This change in texture is what’s referred to as reduced lipid fluidity.
When lipids become stiff, they can't seal in moisture as effectively. As a result, your skin barrier becomes weaker and more fragile, making it easier for moisture to escape and irritants to get in. That’s why your skin feels drier, tighter, and more sensitive in winter.
When the skin is already in a fragile state in winter, the overuse of actives like niacinamide can do more harm than good.
Signs You’re Overusing Niacinamide Moisturizer
If you experience any of the following symptoms, you might just be overusing your niacinamide:
|
Sign |
What to Observe |
Interpretation |
|
Redness & stinging |
Mild burn-like sensation after application |
Indicates barrier irritation |
|
Flaking / dryness |
Fine peeling or patches |
Suggests barrier weakening |
|
Increased sensitivity |
Products that were tolerated now sting |
Reduced tolerance threshold |
|
Dull/tight texture |
Skin feels tight or looks lacklustre |
Loss of suppleness & hydration |
It’s also important to tell purging apart from true dryness or irritation. Purging is a temporary reaction to renewal and shows under-surface breakouts, while dryness is mostly skin-surface stress.
How to Use Niacinamide Moisturizer Correctly in Winter
-
Use once or twice a day depending on your skin’s needs.
-
Combine with supportive hydrators like ceramides and hyaluronic acid.
-
Don’t layer with multiple actives (e.g., acids + retinol) without buffering.
-
Use gentle cleansers which are non‑stripping to preserve barrier lipids.
-
Use a richer final moisturizer or oil to lock in hydration.

Alternatives & Barrier‑Repair Ingredients to Consider
If a niacinamide moisturizer is causing you discomfort, or you simply want to rotate between other ingredients, consider these ingredients that complement or substitute its benefits:
|
Ingredient |
Function |
|
Ceramides |
Key lipids that help reinforce and strengthen the skin barrier. |
|
Panthenol (Provitamin B5) |
Soothes irritated skin and boosts hydration, helps counter niacinamide overuse effects |
|
Squalane |
Lightweight emollient that hydrates without feeling greasy or heavy. |
|
Glycerin / Hyaluronic Acid |
Humectants that draw water into the skin, opposes niacinamide moisturizer dryness |
Switching temporarily to formulations with lower niacinamide concentration (1–2%) may also help restore balance to your skin.
Expert Tips for a Winter Skincare Routine
-
Always patch test begin with using the product on a small area, gradually expanding.
-
Use the “thin to thick” rule to layer your ingredients. Start with ingredients thin in consistency, like a toner or a serum. Then move to richer products like moisturisers.
-
Do not over‑exfoliate your skin, especially in winter, as it may strip your skin barrier.
-
Ensure that you hydrate your skin with moisture and humectants before sealing with emollients or occlusives.
-
If you feel any discomfort, reduce the frequency of your application immediately or stop completely.
Conclusion
Niacinamide is widely considered for its multi‑benefit role in skincare. But sometimes even well‑studied ingredients can betray your skin when overused. In winter, when the skin barrier is naturally under stress, niacinamide moisturizer dryness can occur if used excessively.
To avoid overuse dryness, use concentrations that do not trigger your skin and pair niacinamide with supportive, non‑irritating ingredients. If you wish to personalise your skincare routine, observe how your skin responds to ingredients and adjust accordingly to ensure that niacinamide remains an ally.
