What is the most regretful cosmetic you bought?

In fact, I have been choosing a product called Mary Daijia in cosmetics, which suits me very well.

In particular, the mascara of Mary Daijia is very suitable for people with short eyelashes, and anyone who wants to have thick long eyelashes can use it.

Once I used another brand of mascara, and then I found it didn't work. Super difficult to use, so if you have used a brand, generally don't choose to change it.
