The difference between Heyan and Hera is:

1. Different national companies

1. Heyan: South Korea’s first-line brand, the brand includes almost all Need skin care products, and a full line of makeup series.

2. Hola: An Australian skin care brand named "Hola" acquired by Guangzhou Aoshia Industrial Co., Ltd., a subsidiary of Liby Group.

2. Different foreign names

1. Heyan: Korean products use hera.

2. Hola: Australian products use Hola.

The reason why the two products have similar names:

Guangzhou Aoxiya Industrial Co., Ltd., a subsidiary of Liby Group, acquired an Australian skin care brand called "Hola". Before the brand entered China, Aoxia Company had already started to apply for the registration of the Chinese trademark "Hera" with the China Trademark Office.

So when South Korea’s Hera entered the Chinese market, the name Hera that was supposed to be used could no longer be used, so she changed her Chinese name to Heyan.
