Pimples and fat grains are both common names for the common people. Among them, pimples, which are divided into blackheads and whiteheads, are actually closed or open pimples. In open pimples, the pimple opening is open and appears black due to oxidation of air and some dust. Whiteheads, on the other hand, tend to be some closed pimples. Lipoma is actually the common name of the common people and refers to two diseases that tend to occur around the eyelids. One is milia and the other is sweat duct tumors. In one case, cornea, are white, domed, hard granules. Acanthomas, which are multiple, skin-colored papules around the eyes, can partially fuse into a mass, but pimples do not fuse together. And acne can occur in other areas besides the face, such as the forehead and back, so they are still very different.
