Can't remember the series , please help me remember!

Hai,
I wanted to see these series again that I saw when I was a child So I assume it's from about the 90's .
It was about a blond woman which lived in a forest , ofcourse strangers come in !
But when the woman used like mud on her skin and covered herself completly she became alike some " monster " .

Sorry for the low info
Thx already , I would really like to know the title again and watch them ^^
