Hi @rfries, You will notice I changed the title of your discussion to describe your question a little better and help other members find it who may have some thoughts or suggestions.

I think you mentioned you have been using a CPAP for a couple of months. What type of CPAP mask are you using? Do you think you may have a silicone allergy and the mask is causing it? Has it been oily since you started using the CPAP?

I wrote a long reply with the history of my oily skin and it went away before I could send it. Maybe it was too long. Basically I was wondering if others have had the same. I do inject testosterone and REM sleep may result in the production of more and I know that testosterone causes oily skin around the eyes. Also I workout with weights and that does increase testosterone. Or maybe this has no basis in medicine. I will see my doctor Friday and will ask him.

My mask is the hybrid ResMed F30 and no I have no allergies other than the usual suspects like ragweed. It is really interesting to me that this is apparently not a common side affect.

In case others experience this oil problem, here's what my doctor said. Being unaccustomed to wearing a mask the body could sweat and that would result in oily skin. I've been awake now for 2 hours after a prerry good night (5 events per hour and over 8 hrs. usage) and the oil is still bothering my eyes. I am wiping oil off my eyelids. I have naturally oily skin but not like this. I am waiting for results from blood test measuring free testosterone level. Since starting CPAP I have reduced my testosterone injections by 30%. I have experienced this oil problem before, without CPAP, with high testosterone, the production of which can seem to go out of control at times.
