Hi,
People with Seb Derm often have impaired skin barrier function. This means that our skin is not able to protect us from the environment as well as it should be. As a result, our skin can become inflamed and irritated more easily. The tactful way of saying this is:
“We have sensitive skin.”
It’s code for – our skin barrier is not working and isn’t doing its job.
We don’t know which came first – impaired skin barrier or Malassezia – in the seborrheic dermatitis continuum. However, we know Malassezia is present on the surface of normal skin and is found everywhere on everyone. Numbers of surface Malassezia is not higher in Seb derm sufferers but Malassezia levels in the stratum corneum is notably higher on skin affected by seborrheic dermatitis.
Some researchers proposed that a defective skin barrier is the root cause of seb derm. Once these changes occur, it encourages Malassezia growth and penetration, causing inflammation which further damages the walls of defence.
Repairing and maintaining a healthy skin barrier may be one of the best ways to prevent seborrheic dermatitis and maybe even cure it. You can do this by a multi-pronged approach of topical creams, diet and lifestyle changes.
