Hard, red bumps may occur on arms and legs normally around follicles. This can be an accumulation of Keratin and dead skin cells on the follicle also known as Keratosis Pilaris. The bumps that form can usually be felt before they are seen as they are dense and may itch. These often the size of a grain of salt and look like goose bumps that are constantly present. KP does not always create red bumps sometimes they appear to be skin colored. This skin condition gets gradually worse in the Winter and may go away in the Summer. In most cases, KP is self-limiting and ends with age. Females often experience this worse then men. Keratosis Pilaris is very common and can appear to be dry skin to the naked eye.
