Even if you apply hand cream diligently, your fingers will get rough quickly in winter. For authors who work in water without wearing rubber gloves, their fingertips often crack. If you wash it in such a state, it will stain and you are worried about hygiene. So, I bought "Coroskin ", which I knew the name for a long time, and tried it.


Coroskin developed by Tokyo Koshisha is a "liquid adhesive plaster" that is useful for treating small cuts, scratches, hangnail, and rhagades. It is a liquid containing "pyroxylin", "d-camphor", "benzyl alcohol", etc., and when applied to the affected area, it dries immediately and turns into a transparent film. By covering the affected area like a film, it blocks water and detergent from entering the wound. Unlike ordinary adhesive plasters, it can be used without hesitation on joints that bend and stretch.



The clear and viscous liquid gives off a slight odor, but when I apply it, I am impressed with how well it fits on the skin. Water does not soak into the ridges on my fingertips, making washing much easier. Since it is a very thin film, it will come off naturally after repeated water work and bathing, but if you want to remove it in a hurry, you can remove it with a steaming towel or nail polish remover. It is possible that the film that has peeled off from the skin may be mixed into food, etc., but it is explained that there is no harm because it is excreted without being digested and absorbed by the body.


Coroskin that protects your rough fingers. If you have a lot of water work, why not try it? It comes in 11ml (0.37us fl oz) and costs about 950 yen. There is also a 2-piece set (5ml (0.17us fl oz) x 2) that is easy to use for home and work, for yourself and for children. Please note that it cannot be used on large wounds, affected areas with suppuration or heavy bleeding, around the eyes or face, or on skin damaged by shaving or hair removal.
