If only in one place that it is likely because of eczema, and the cause is allergies or it could be due to chronic scratching continuously.
If allergies cause must be sought allergic to anything, and we avoid, whereas if the result of scratching it should not scratch-scratch.
Because if it feels good to scratch, scrape the skin, new skin comes thicker, harder carded and so on. Well this cycle we must break with the provision of cream and also not carded. Easily cured hopefully guaranteed.
