First of all, you can tell the authenticity from the packaging. The difference lies in the text on the packaging box. The top English letters "ROUGEPURCOUTURE" are not particularly thick, just a little thicker than the bottom letters. Moreover, the font on the genuine packaging box is overall slender and comfortable, while the fake ones are rough and even have a little stain. The picture below shows the true left and false right.

Look at the batch number on the bottom of the outer packaging. The batch number on the bottom of the authentic product is hand-engraved. Very thin and delicate, but very clear. Most of the fakes are printed with a whole mold, the fonts are rough, and the whole is not refined. The picture below shows the true left and false right.

Looking at the lipstick logo, the black line of the fake logo on the left is longer than the real logo on the right, and the line behind the fake logo is thinner, while the real logo is slightly thicker and more delicate.

The trademark at the bottom of the genuine product is relatively correct, and the spacing between the characters on the genuine product is almost perfect, especially the spacing between the characters and the underline. There must be a gap, and fakes often fail to achieve such sophisticated technology.

The smell of authentic YSL lipstick is the floral and fruity fragrance of peach, but it is not very strong, while most fakes have strong chemical substances or other smells. Pay attention to your identification.

As far as the overall quality of the lipstick is concerned, the authentic YSL lipstick weighs about 40g, while the fakes often do not reach this weight and the texture is also very poor.

In terms of price, most YSL lipstick prices are around 300. If the purchase price is too low, it may be a fake.
