Expired Glycolic Acid
The theory of decadent glycol
There is decadent glycol in the world, and its properties may be different from those of ordinary glycol. Fugenol has a specific nature and can be used for all kinds of purposes, but once it is decadent, everything changes.

The quality of decadent glycol gradually shifts. At the beginning, there may be a peculiar smell coming out, but it is no longer fresh, like the smell of rot, which is faintly scattered around. Looking at its color, it is not as clear as it used to be, or it is slightly yellow and gradually turbid, as if the marks of time were stained in it.

Its use is not as good as before. Often, glycol can be used as a moisturizing thing, applied to the skin, and can make the skin moist and smooth. However, if decayed glycol is used, it will not only have no nourishing effect, but will be harmful. Apply it to the skin, the skin may feel uncomfortable, itchy and painful, and even rash and redness, as if it has been attacked by evil.

Investigate the reason, as the years go by, the internal components of glycol change over time, the original structure disintegrates, and the new thing may be harmful. Therefore, when encountering decayed glycol, you must not use it lightly, and you should discard it, so as not to leave a disaster on your body. It is wise for everyone to observe the changes in things and judge the situation.
