The main differences are: the transparency of colloid, the smell and the material of jar.

the lighter color is the genuine product, and the darker color is the fake product.

what is clear at the bottom is genuine, and what is vague is fake.

the colloid with good light transmittance is genuine, and the colloid with poor light transmittance is fake.

the genuine colloid is transparent and has a faint fragrance, and the plastic of the jar is very hard, so the lid often breaks during transportation.

Fake, the colloid is turbid, and it has a strong smell of cheap essence. When it is painted, it immediately turns into water, and the jar is soft and can be pinched and deformed.

the side with the duck in the picture is genuine.
