Why does the eye patch under the eye bags smell like a tire?

The reason why the eye mask with eye bags removed smells like a tire is because of the patented hydrophilic gel technology. According to the relevant public information, the pouch sticker is specifically aimed at the problems of Chinese people's bags under the eyes, dark circles and eye lines. The product adopts patented hydrophilic gel technology, which is different from ordinary eye mask. The eye bag patch made by this technology will inevitably have a smell, which is called fetal smell.
