What is a callus?
A callus is a toughened area of skin which has become relatively thick and hard in response to repeated friction, pressure, or other irritation. Rubbing that is too frequent or forceful will cause blisters rather than allow calluses to form. Since repeated contact is required, calluses are most often found on feet because of frequent walking, most commonly on people who walk barefoot or wear open heel footwear. Calluses also form on the hands of weight lifters, carpenters, and string musicians, for example. Calluses are generally not harmful, but may sometimes lead to other problems, such as skin ulceration or infection.
What are the causes of calluses?
Normally, a callus will form on any part of the skin exposed to friction over a long period of time. For example, people often develop calluses on the middle finger of their dominant hand due to writing with a pen or pencil. Another cause is from playing string instruments like the guitar or the violin; calluses will develop on the four fingers of the hand used in holding the strings down to the fingerboard, and sometimes on the fingers of the hand used for pizzicato or strumming. Calluses are also very common on the fingers of bassists who use both the pizzicato and slapping techniques. This also applies to rock climbers on almost all of their fingers. There are many activities that can result in the formation of a callus, and having one is sometimes viewed as a badge of honor.
What is the working principle behind the callus peel?
It is almost the same principle as a facial peel, using AHA (alpha-hydroxy acid) products.
How often do you need to do the callus treatment?
2 - 3 sessions spaced 4 weeks apart.
