Home care measures
Skin - dry; Winter itch; Xerosis; Xerosis cutis
- Moisturizers, especially creams or lotions that contain urea and lactic acid
- Topical steroids for areas that get very inflamed and itchy

Prevention

- Do not expose your skin to water more often than needed.
- Use lukewarm bath water. Afterward, pat the skin dry with the towel instead of rubbing.
- Choose gentle skin cleansers that are free from dyes and perfumes.
