It looks like gorgeous former "Knots Landing" star Joan Van Ark has been using her nighttime soap correctly!

The 64-year-old natural beauty turned up at a Beverly Hills charity event on Thursday, looking a million times better than she did back in December.

Thankfully, Joan is one Hollywood actress not getting injected with motor oil. She looks good!
