Malassezia Globosa causes seborrhea, Pyrithione Zinc is effective

Written by on February 11, 2008 in dermatitis, seborrheic dermatitis with 8 Comments

Interesting threads on the Rosacea Support Forum started by Artist. Apparently it is well known but it was a surprise to me that seborrheic dermatitis is not caused by Pityrosporum ovale, but in fact Malassezia Globosa. The second bit of information that was surprising to me was not only that ketoconazole is effective against M. Globosa, but so is Pyrithione Zinc (PTZ).

Some great links to heaps more information and the ongoing discussion here ;

    how pyrithione zinc acts on Malassezia globosa

  2. David Pascoe says:

    The theory is that PTZ acts as an anti-fungal so is effective in eliminating M. Globosa, a type of yeast.

    When people have this problem like seb derm, and this yeast lives on our skin. Are we sensitive to foods we eat that contain yeast, or foods that feed yeast,example dairy products, breads, sugar etc.

    But how do other people who eat these products never seem to get this. Or will they eventually.

    Hi Maureen,

    that is a good question that I can’t answer. Anything is possible I guess, but I would think systemic intolerance to yeast is not related to seborrheic dermatitis. I doubt that foods that yeast feed on make much difference, but again anything is possible.

    We do know that systemic antibiotics can kill off flora and lead to candida – but that is something different I believe.

    Hi Digital Davo, thanks for your comment. Do you know if the Promiseb Topical Cream is available for use here in the U.S, or is there ither things to try like Born to Be Mild Medicated Cleanser.
    Do you at all think this is also related to Rosacea?
    Thanks–Maureen

    Looks to me like they are about to start promoting Promiseb in the US, so perhaps we’ll start seeing it become available soon.

    I think for some rosacea sufferers, SD can be a parallel issue. Thus having some good treatments that might be gentle enough for rosacea sufferers to us is a good thing.
