No deterioration! This is the common sense of perfume. Alcohol will not volatilize after the perfume is placed for a period of time, so it must have a strong smell of alcohol when you take it out. Fake goods are not fake goods are not a problem. Even Chanel Dior, a big-name perfume, has this situation. It's normal! If there is no alcohol in perfume, it cannot be called a good perfume. The higher the grade of perfume, the higher the alcohol content. This is why the new perfume has a strong smell of wine when it is first opened. Alcohol will evaporate after several uses.

One more thing, I don't know which brand you are talking about. If it is a big brand perfume, there must be a production batch number, but the shelf life must not be marked. Unless marked in Chinese.

Besides, since you said you bought it at the counter, it can't be a fake.

What brand is holy water?
