1. Look at the outer packaging

The outer packaging paper of the genuine product is slightly rippled, while the fake product is very smooth. The words ROUGH PUR CONTURE are bolder on the fakes than on the genuine ones.

2. Pay attention to the length of the tube body

As shown in the picture below, the distance between the genuine product is 7.5mm and the fake one is 9.5mm, which is a difference of 2 mm.

Comparison of the bottom labels, the genuine "ROUGE" is connected together, while the fake ones are separated.

3. Look at the paste

Due to the problem with the fake mold, the fake lipstick looks fatter, and the bottom of the paste is smaller and concave inwards.

The authentic Yves Saint Laurent lipstick is a vertical straight line with a perfect outline.

4. Look at the weight

Due to the different production raw materials, the weight of the fakes must be different. There is a difference of 7 grams. The genuine products are heavier and the fakes are lighter.

The weight of the authentic Yves Saint Laurent square tube lipstick is about 41 grams.
