Niacinamide does not expire, but it does degrade over time. Niacinamide is a vitamin B3 derivative; therefore, like all vitamins, it loses its potency as it ages.
Exposure to light, heat, and moisture affects how quickly it degrades. You should expect your Niacinamide to start degrading after about two years of using it.
In this article, we’ll discuss whether or not Niacinamide expires, how long Niacinamide can be stored before it goes bad and what happens if you use expired Niacinamide on your skin.
How Long Can I Use Niacinamide after the Expiry Date?
There’s no hard and fast rule about how long you can use Niacinamide after the expiration date.
The best way to determine if a product has gone bad is by smell and appearance. If it smells bad or changes in consistency, discard it.
As long as the product still smells fresh and looks good, there is no reason to worry about using it after the expiration date. The only thing that matters is ensuring that the products do not cause any damage to your skin.
What Does the Expiration Date Mean?
The expiration date is the last day a product is safe for use. It means that the product will continue working after this date. It means there’s no guarantee of its efficacy. The only way to tell whether your Niacinamide has expired is by looking at the label.
How Do I Tell if Niacinamide has Expired?
Niacinamide is a water-soluble vitamin used to treat acne, rosacea, and skin sensitivity. Manufacturers and brands determine Niacinamide’s expiration date, but it is usually printed on the label.
To check if your Niacinamide has expired, look for these signs:
● The product turns yellow or brownish. This happens because of oxidation.
● You notice crystals forming at the bottom of the bottle
● A change in texture.
What Is the Difference Between the Expiry Date and Best Before Date?
The expiry date is the last day a product is guaranteed safe and effective, while the best-before date is a recommendation for when you should use it.
The manufacturer determines it, so you can trust that they know what they’re talking about when they tell you your product should be thrown out after two years.
The best-before date is a recommendation given by the manufacturer, but it can sometimes indicate when your product expires. It could be much longer than that.
How To Store Niacinamide?
It would be best to store your Niacinamide in a cool, dry place. Avoid direct sunlight and high temperatures. Please keep it away from moisture and humidity.
Niacinamide has a shelf life of about 36 months, but it can be damaged if exposed to extreme temperatures or other environmental factors that could cause oxidation. Keep your Niacinamide in an airtight container when not in use to protect its potency for more extended periods.
Does The Niacinamide Expiry Date Matter?
Yes, the niacinamide expiry date does matter.
The expiry date is essential for your safety and the product’s effectiveness. The effectiveness of your Niacinamide may be compromised after its expiration date.
The expiry date on a product indicates how long it will remain at its highest quality before it begins to degrade in some way. This degradation could affect the potency of your Niacinamide and make it less effective at treating acne or helping with other skin problems.
How Do I Tell If Niacinamide Has Gone Bad?
The expiry date on your niacinamide bottle doesn’t have anything to do with whether or not you can use the product after that date. The expiry date is only for the safety of the consumer.
The best way to determine whether your product is still good is by checking the color, smell, and consistency. If it looks or smells funny, you probably won’t get any benefits from it.
Is It Safe to Use Expired Niacinamide?
You can safely use Niacinamide after the expiry date on the bottle. However, it may work better than before the expiry date. If you notice redness or unusual effects after using expired Niacinamide, you should toss it off.
You should also throw away any skincare products past their expiration dates. You should never use products that have gone bad because they can cause irritation and breakouts on your skin.
Niacinamide does expire; therefore, it is vital to check the expiration date before using it on your skin. If you have unopened bottles of Niacinamide that are past their expiration date, you can still use them as long as there are no signs of mold or other visible signs of deterioration. However, the effectiveness of Niacinamide may be reduced after the expiry date, so it is recommended that you use it before its expiration date.
