You can use the following methods to identify the authenticity of Neutrogena shower gel:

1. The color of the genuine product on the front is relatively bright, and the excessive color is more natural. There is a product in the upper right corner of the words Neutrogena. The registered trademark is small R, but the fake one does not.

2. The back is mainly about the date. The date of the genuine product is embossed, and the printing is very clear, so you can tell the date at a glance. However, the technology of imprinting the date on the back of the fake Neutra cleansing cream is not very good. Some of them cannot tell the specific number even if they are carefully identified.
