What can I do to make my Eczema better?

Changes to how you wash

  • Use a soft towel and pat yourself dry (rather than rubbing)
  • Avoid using soaps – try using oily moisturiser instead
  • Don’t use bubble bath
  • Add unfragranced oils to your bath

Changes to your clothes

  • Use sensitive-skin detergents in your washing machine
  • Allow only cotton to be in direct contact with your skin wherever possible

Changes to how you moisturise

  • Use moisturiser as often as possible, particularly after washing
  • Use moisturisers that are unfragranced
  • Switch between moisturisers until you find one that works well for you
    • Usually oily moisturisers are more effective but they may not be absorbed as easily
    • You don’t need to buy expensive moisturiser – cheap moisturisers are just as good

Other measures

  • Stay well-hydrated
  • Install an air humidifier where you live/work/sleep

Commonly used medications

  • Antihistamines
    • For itching
  • Topical steroid creams & ointments- these should be used at the lowest effective strength as they can cause significant side-effects. They should only be used in addition to the measures described earlier.
  • Antibiotics- if skin infection is thought to be playing a part in the Eczema
  • “Occlusion dressing”- the practice of applying moisturiser thickly under cotton bandages & gloves to treat eczema in children
  • Less-commonly used medications, usually under the guidance of a specialist include:
    • Ultraviolet light therapy
    • Coal tar ointment
    • Immunosuppressant medications
