What is a moisture lesion?

A moisture lesion is damage to the skin caused by prolonged exposure to moisture. It is sometimes called incontinence-associated dermatitis in adults or nappy rash in children.

A moisture lesion is often mistaken for a pressure ulcer.

What causes a moisture lesion?

The skin acts as a natural barrier against moisture, bacteria and disease. Healthy skin has a balanced pH level. When skin is exposed to moisture for a prolonged period, it can cause burning and damage to the area.

This is often more noticeable in older people because the skin becomes thinner with age.

How serious is a moisture lesion?

A moisture lesion may start as a minor problem but can quickly become more serious.

Pressure or friction on a moisture lesion can increase the risk of developing a pressure ulcer.

What can I do if I have a moisture lesion?

If you are incontinent of urine or faeces, you may be at risk of developing a moisture lesion.

If you think you have moisture damage or a pressure sore, contact your GP or healthcare professional. They will arrange an assessment and provide advice.

How can moisture damage be prevented?

  • wash the area using a pH-balanced cleanser, such as wipes or sprays. Do not use soap, as it is alkaline and may cause further irritation to the skin
  • use a barrier cream, such as Derma S, to protect the skin from damage caused by soiling
  • do not use thick creams, such as Sudocrem or Germolene, or talcum powder, as these may reduce the absorbency of continence pads
  • try to remain mobile and avoid sitting for long periods, as this may increase the risk of developing a pressure ulcer.

How is moisture damage treated?

  • your healthcare professional will assess and treat the moisture lesion using a cleanser spray and protective gel, such as the Proshield system
  • once the skin has improved, treatment will focus on preventing further damage using a barrier cream, such as Derma S
  • once the skin has healed, your healthcare professional may advise you to continue using Derma S to help prevent future damage.  You will need to ask your GP to prescribe this product.
