Yes, it's quite interesting to already see a positive correlation with Seborrheic Dermatitis around the lips and on the scalp. Does anyone who hasn't taken the survey also have any peeling elsewhere? If so, can you distinguish between sebhorreic dermatitis and psoriasis?
Reading about Seborrheic Dermatitis on wikipedia and the potential link to the Malassezia yeast. It usually presents in areas rich in sebum, which as many people know, the lips do not have sebaceous glands. However sebum does reach the lips from the area around the lips.
And interesting to read the beauty article linked on wikipedia that says:
"Malassezia hydrolyze human sebum, releasing a mixture of saturated and unsaturated fatty acids. They take up the required saturated FAs, leaving behind unsaturated FAs. The unsaturated FAs penetrate the stratum corneum and due to their non-uniform structure breach the skins barrier function. This barrier breach induces an irritation response, leading to dandruff and Seborrheic Dermatitis ."
