Is this authentic or fake

hii, i just got my first labubu from second hand in Korea so the box is opened but the doll still sealed in the foil.

I bought the same color as the user DouShaBao_w but mine look smaller and less chunkier😭

i noticed the difference on the face shape, mine look less oval.,

the QR can be scanned and redirected to the authentic web and the code is working
