Perfume and fragrances are everywhere, so you probably have an understanding of what a top, middle/heart, and base note are and what perfume is trending right now, and that's probably about it. Don't get us wrong, we love watching PerfumeTok as much as the next person, but there is so much more to learn about fragrance than just new products. 

There are so many unknowns when it comes to fragrance. Does it last forever? Why does something smell amazing on someone else and awful on me? Should I rub perfume in? We're here to demystify some common perfume myths.

Does perfume expire? 

Yes. Perfume, like any other cosmetics, does have an expiration date, but it's not necessarily something that you'll see on the bottle. If you're looking for an answer about when all perfume expires, unfortunately, we can't give you an exact date.

Each perfume has a different lifespan. However, the general rule of thumb tends to be that when a perfume starts to smell a bit off, it's time to get rid of it. It is also worth noting that to make a perfume last longer, proper storage is key.  Keep it away from heat and store in a cool and dark place. 

Do fragrances smell the same on everyone? 

No. Although a perfume has its notes, the scent will be different on every single person. The reason it smells different on everyone is because perfume interacts with your body chemistry. Everyone's body chemistry is different; that's why something might smell amazing on a friend of yours but not smell as good on you or vice versa. 

What does rubbing in your fragrance do? Should I be doing it? 

The answer is no. In fact, instead of making the fragrance stronger, it actually makes it weaker. According to Eisenberg Paris, the rubbing breaks down the fragrance molecules, which makes the scent disappear.
