Perfume ingredients are not printed on packages as producers consider them to be company secrets.
Doctors suggested consumers test for an allergic reaction before they purchase a new perfume.
"There are several thousand potential allergy inducing substances, and it is hard to tell which one causes the allergic reaction when people get skin irritations," said Shi Yuling, director of the department of dermatology at Shanghai's NO.10 People's Hospital.
Some consumers spray fragrance on different parts of their body and may not notice small skin irritations, Shi said.
She said allergic reactions to perfume are not that common but suggested potential buyers apply a sample on their skin and wait 48 hours to see whether they have a reaction before buying.
Some perfume enthusiasts said they would be more cautious in future when purchasing a fragrance.
"I will see whether there will be a sales ban or not from the EU before I decide to present it to others or use it myself," said Cherry Wang, who works in advertising and received a bottle of Chanel N 5 as a gift.
