If the problem of corns has not passed into the chronic stage or you have encountered it for the first time, you can try to localize it or gradually eliminate it with fairly simple means.
To do this, you will need a bath with warm water, foot cream, a good band-aid and a lot of patience. It will not be possible to cope with this task at once. Therefore, the process of helping yourself will have to be repeated several times.
So, first — a warm bath. Hardened keratinized tissues need preliminary softening. You can add sea salt or pharmaceutical herbs that have anti-inflammatory effects, such as chamomile, to the water. When the surface of the corn becomes softer, proceed to gently remove the upper stratum corneum with a pumice stone. Then you should treat the foot with a foot cream with softening and moisturizing properties. The range of such creams is very wide, the effect of the application is the same on average, so it makes no sense to give a specific recommendation.
In conclusion, you should close the problem area with a band-aid. This is especially true if in the near future you have to put on shoes and go somewhere on your own business. The product line of specialized patches is also very large. For some of them, manufacturers declare medicinal properties.
