Which one is correct?

I think you're expressing two different things. If, since seeing them, you've forgotten how they looked at that moment in time, you say
"I've forgotten what you looked like"
If you're unable to imagine what they currently look like because it's been so long since you've seen them, then
"I've forgotten what you look like"
seems more appropriate.
