Painful callus is most often wet (wet) - with the formation of a blister in the area of excessive pressure or friction of the skin, but dry calluses, primarily core calluses, can also cause pain when walking.
Dry callus - due to the presence of an intradermal rod formed by an accumulation of dead skin keratinocytes, it is sometimes defined as an internal callus.
One of the hardware methods of getting rid of calluses is their destruction using such a cryo-liquid as liquefied nitrogen, which has a temperature of -195.8 ° C in this state of aggregation.
As you know, corns are divided into wet (wet) and dry (hard). Thus, a hard callus - a thickening of the outer (horny) layer of the epidermis, consisting of dead keratinocytes - is a dry callus.
