Dressings for Eczema

covering / ointment fixation / semi-occlusive / semi-permeable

For decades, dressings such as body suits, dressing gloves and tubular bandages have been used as a component in the treatment of moderate and severe eczema. Dressings are primarily used as a cover to prevent scratching and irritation from rough textiles as well as securing the ointments used for treatment. Patients and parents of patients with eczema indicate that the use of dressings helps to keep the condition under control.

Purpose

The DermaCura dressing is a medical device for covering and securing the ointments used to treat chronic skin diseases such as eczema and psoriasis. The primary purpose of DermaCura is to reduce itching, which is the most common complaint of eczema sufferers. It is designed to protect damaged skin, reduce itching and prevent scratching by creating a mechanical barrier for the affected skin. Furthermore, the unique smoothness and extremely fine structure of the material—see image below—ensure it reduces itching. In summary, DermaCura dressing is a soft, semi-permeable and semi-occlusive dressing which contributes to an improved moisture balance of the affected skin.

itching / itching prevention / fibres / fibre structure

The primary purpose of DermaCura is to reduce itching, which is the most common complaint of eczema sufferers. It is made using an extremely soft fibre that is softer and smoother than other materials—for example wool or cotton. These thin, smooth fibres are preferred because they prevent irritation of the hypersensitive skin associated with eczema and eczema-related conditions.

The illustration above shows the smoothness and extremely fine structure of the DermaCura eczema dressing. These properties make it very comfortable to wear.

Another intended effect of DermaCura eczema dressing is to improve the moisture balance and the absorption of wound fluid in wet eczema. The moisture-regulating capacity of the DermaCura dressing ensures a good fluid balance in the affected skin of patients. Research shows that the absorption of water is much greater with DermaCura than with other materials. In addition, TEWL measurements have shown that the fibres of the DermaCura dressing improve the function of the skin barrier. In preference tests, users were found to prefer the fibre of DermaCura in comparison with their own clothing.

TEWL

Transepidermal water loss (TEWL or TWL) is the loss of water that passes from inside a body through the epidermis (that is, either the epidermal layer of animal skin or the epidermal layer of plants) to the surrounding atmosphere via diffusion and evaporation processes. TEWL in mammals is also known as insensible water loss (IWL), as it is a process over which organisms have little physiologic control and of which they are usually mostly unaware. Insensible loss of body water can threaten fluid balance; in humans, substantial dehydration sometimes occurs before a person realizes what is happening. Measurements of TEWL may be useful for identifying skin damage caused by certain chemicals, physical insult (such as “tape stripping”) or pathological conditions such as eczema, as rates of TEWL increase in proportion to the level of damage. However, TEWL is also affected by environmental factors such as humidity, temperature, the time of year (season variation) and the moisture content of the skin (hydration level). Therefore, care must be taken when interpreting the meaning of TEWL rates.

DermaCura dressing fibres have a unique structure that is made of increasingly finer fibrils. These fibrils are the smallest hairs that make up the complete fibre. Microscopically small channels between these fibrils regulate the moisture balance of the affected skin. This fibril structure and the moisture-regulating properties of the DermaCura fibres are unique compared with synthetic structures which do not absorb moisture.
