A long lasting perfume can make you feel better, but it’s hard to tell what you’re getting with a fragrance that lasts up to three months. 

In a recent article in The Journal of Experimental Dermatology, Dr. Yael B. Shapiro, a dermatologist in Tel Aviv, Israel, discovered a method that can find a scent that lasts as long as two months without the smell. 

Shapiro’s technique is based on the concept of a coffee coating, in which a tiny amount of coffee extract is added to the formula of a perfume. 

The formula then absorbs the coffee extract, which allows the fragrance to stay on your skin for up to four weeks. 

If you have sensitive skin, this technique can be tricky to use. 

“It is not an easy way to use, because you need to carefully balance the amount of the extract and the amount you apply to your skin,” Shapiro told the Daily Dot.

“I think a lot of people have trouble applying the extract, and that’s a big problem because they can’t smell the fragrance, and they think the scent will get stronger when you apply more of it.”

Shapiro is now experimenting with new methods to create a longer lasting fragrance.
