Hi Helen536, I found the following info on the apdaparkinson's.org website. Hope you find it helpful.

Parkinson’s disease (PD) can cause a whole host of non-motor symptoms, including symptoms related to the skin. This week we take a closer look at these problems.

Seborrheic dermatitis — patches of scaly, irritated skin
Seborrheic dermatitis is a common skin condition in the general population, but even more commonly found in people with PD. It causes patches of scaly, red skin and dandruff, primarily on the scalp and on the oily parts of the face such as the sides of the nose. In PD, it is thought to be caused by over-secretion of oils from the sebaceous glands in the skin. In much the same way that dysfunction of the autonomic nervous system (the nerves that control automatic body functions) cause non-motor symptoms in PD such as blood pressure dysregulation and urinary abnormalities, autonomic dysfunction of the nerves that control the oil glands of the face can cause seborrheic dermatitis.

John563, same problem. Gaberpenten seems to being doing the job. 🍎

Yes, recently itchy spot develops on arms or legs with a pink circle around it. Never thought this could be PD thanks. Putting cortisone on now, itching stops almost immediately.

Thanks for the heads up!

My nose itches sometimes - very annoying. I never thought of it as a PD symptom but now I might have an answer.

Yes bottom of my feet! Intense. Neuro says it is peripheral neuropathy. Cortisone cream works well. Family Dr wants me to try gabepentin
