Causes of Malar rash
Malar rash is caused due to the blocking of the sweat glands. These glands or ducts are on and under the skin. When these sweat ducts are obstructed, it traps the sweat. This causes swelling of skin, itchiness and development of malar rash. Due to this,blisterswhich are sometimes filled with fluid, and reddish bumps develop, eventually causing irritation.
The sweat ducts can get blocked due to many reasons. Some of them are as follows:
- Infants have less developed sweat ducts which are prone to easy bursting. A damaged sweat duct traps the perspiration under the skin. The damage could be for the reason that the infant is heavily clothed, kept in incubator, has a high body temperature, or has been exposed to hot environment.
- Rigorous exercise or activities leads to clogging of sweat ducts causing development of malar rash.
- Excess application of ointment or cream may also block the sweat ducts.
- Skin fitted and tight clothes, as well as certain types of non-porous fabric can also stop sweating causing malar rash.
