Thank you for this helpful reply. My wife is sensitive to the sebum odor.

Try these tips
Carry blotting wipes with you. These little papers are designed to soak up sebum, not just wipe away sweat. Using them throughout the day when you notice build-up on your face, scalp, or neck can effectively control odorous sebum secretions.

Add a face and neck wash to your daily routine. Make sure that dermatologists recommend the products you use. Some good ingredients for sebum control to keep an eye out for include tea tree oil, aloe vera, salicylic acid, and niacinamide.

Invest in shower equipment that can help with mobility issues. Consider adding a detachable handheld shower head or a long-handled shower brush or sponge to help you clean hard-to-reach places.
Store baby wipes in your bathroom, purse, or car. That way, if you notice body odor during the day, you can quickly address it without having to disrupt your day to shower.

If motor symptoms make applying deodorant difficult, consider using a spray deodorant or asking a care partner for help.

Speak to your doctor about any concerning smells. While they may be related to Parkinson’s, differences in body odor can also be indicative of other issues, and it’s important to mention any changes you might notice to your primary care physician or movement disorder specialist.
