There is not enough applicable evidence to make a clear general seb derm recommendation for Creatine. Its conditioning role is separate from a laboratory finding that Malassezia furfur can use it as a nitrogen source.

That experiment used a minimal culture medium with a lipid source. It supports a theoretical mechanism question, without showing that a cosmetic containing Creatine feeds yeast on your skin or causes a flare. No applicable human seb derm benefit was established. Judge the full formula and your own repeated response, and seek advice if symptoms persist.
