Lauric Acid is best treated as a cautious avoid during an active seb derm flare or when you are following a strict Malassezia-conscious routine. It is a C12 fatty acid, and laboratory work shows that fatty-acid uptake machinery from some Malassezia species can use lauric acid. That creates a theoretical concern, but it does not prove that every product containing Lauric Acid will trigger symptoms.

The laboratory picture is not a finished-product test, and results vary with the Malassezia species, the fatty acid and how the lipid is supplied. In skincare, a small amount in a rinse-off cleanser is not the same exposure as a fatty-acid-rich leave-on product. If you want the simplest cautious choice during a flare, choose a formula without Lauric Acid. Otherwise, stop using a product if it repeatedly increases itching, redness, tightness or stinging.
