There is not enough applicable seb derm evidence to give Lactoperoxidase a clear general recommendation. Its recorded cosmetic purpose is light stabilisation, which does not establish a treatment action on skin.

Checked research concerns complete enzyme systems, oral lozenges or mixed toothpastes, with additional substances needed for those systems’ activity. Skin and oral environments also differ. These findings cannot isolate a cosmetic seb derm benefit or exact Malassezia response from this enzyme. Consider the full formula and intended use, and ask for advice about continuing irritation.
