If you’ve ever wondered how long does niacinamide last, this is the article for you.
We’ll cover everything from shelf life, to expiration dates and more.
How Long Does Topical Niacinamide Expire?
The shelf life of topical niacinamide depends on the packaging. It’s usually between 18 months to about 3 years, but it may vary depending on the brand.
If you have topical niacinamide that’s expired, there’s no reason not to use it up.
You can simply throw away any leftover product after you’ve used up all of the contents—or if you’re worried that something might be wrong with your skin after using an expired product, consult with a dermatologist before continuing to use it.
How Do You Tell If Your Niacinamide Has Expired?
Here are some things to look for if you think your niacinamide has expired:
1. Check the expiration date on the package.
If it’s not there, you can still use it if you’re certain that the bottle was manufactured recently.
2. Check for damage to the packaging or container.
If there’s a dent in it or cracks in the lid or bottom, throw that baby out!
You don’t want to take any chances with this stuff.
3. Look at how much product remains inside of your container
If there’s less than half left, then toss that bad boy right into the garbage where he belongs.
That way you won’t risk getting an upset stomach (or worse!).
4. Change in color
The best way of knowing if it’s safe is by looking at the expiration date and checking how long ago it was made.
If there’s no expiration date or it has passed it, then throw away whatever amount remains as soon as possible.
5. Change in odor
Slight changes in odor aren’t always cause for concern; however, if these smells get stronger with time and smell foul or rancid then throw away what remains immediately.
6. Change in texture
Niacinamide goes bad when its texture changes significantly due to microbial growth inside which makes it look more oily than usual.
Is It Safe to Use Expired Niacinamide?
You’ll want to make sure you use your niacinamide within its expiration date.
However, it’s also important to consider whether or not expired niacinamide should be used at all.
If you see that your bottle of topical niacinamide has expired, don’t worry; the skin care product is still safe for use up until that point.
Once a topical product reaches its expiration date and is no longer effective in the way it was intended, there’s nothing harmful about continuing to use it—aside from the fact that there may be some side effects associated with using an outdated formula (more on this later).
However, if you see signs of discoloration or other irregularities in your topical niacinamide (it looks like it has gone bad), throw away any remaining product and get a new one from the drugstore or pharmacy before using again!
What Happens if You Use Expired Niacinamide?
So, what happens if you use expired niacinamide?
You won’t die or anything.
The good news is that niacinamide is not toxic or harmful in any way.
However, there are some side effects you might experience if your skin absorbs too much of the vitamin: redness and swelling of the skin as well as mild irritation and itching.
If you have any concerns about using expired niacinamide, please talk to a dermatologist for more information.
Can You Freeze Your Niacinamide to Extend its Shelf Life?
You can freeze your niacinamide, but you’ll want to take a few precautions first.
- Make sure you’re using an airtight container or bag to store it in the freezer
This will help prevent moisture from getting into your product and allow bacteria to grow.
- Use expiration date on frozen products as a guide only
They aren’t always accurate since storage conditions can change the quality of what’s inside that package.
The best way to tell if something has spoiled is by checking its odor and appearance: if either of those changes, toss it out immediately!
How Can You Tell If Your Niacinamide Is Bad or Spoiled?
If you are concerned about the shelf life of your niacinamide, contact the manufacturer.
If you have any questions about your product or its expiration date, the company will be able to give you a definitive answer.
If you think that your niacinamide has expired, here are a few ways to tell:
How Do You Store Your Niacinamide Properly?
Niacinamide can be stored in a cool, dry place.
It is important that you keep the product away from heat, as extreme temperatures can cause the product to lose its effectiveness.
Niacinamide should also be kept out of sunlight, which could cause it to become discolored or ineffective.
Also, keep your niacinamide away from children and pets.
Children may mistake it for candy and eat it, while pets might chew on the bottle or lid and make a mess.
Now that you know all about the shelf life of niacinamide and how to tell when it has expired, it’s time to start using your product!
Remember that you can always freeze it in case it expires before you’ve had a chance to use up all of its contents.
You may also want to keep an eye out for signs of spoilage, such as mold growth or foul smells coming from inside the container.
If any of these things happen, toss out whatever amount remains so that no one gets sick from using contaminated products—and remember: always keep an unused portion away from where food is prepared or stored so as not to contaminate anything else!
