Slimy face after eating "healthy"

Hello,

maybe someone here knows what's up.

When I eat and drink good, like lots of vitamin C or green tea, when I wash my face, my face is more slimy feeling like there is some coating on it. When eating not so good, my face and sweat were more sticky than slimy.

It feels like some very weak aloe vera mask..

Anyone has an idea if this is good (toxins moving out of body) or something else?

Thank you people!
