Curious(Curious)

I'm trying to describe the facial expression people make when they're unsure, curious, deciding, or trying to understand something. The expression consists of closing the eyelids half-way, not evenly, but as if shrinking the eyes, wrinkling the brow and eyebrows, and sometimes tilting the head, as if to trying to understand it from a better angle. Is there any verb that represents doing this?

I don't know a word for it either in English, in Spanish, in German, in French, or in Japanese, so I couldn't use Google Translate to figure it out. I tried describing what it looks like, like I did in the previous paragraph, on Google and hoping to find someone else who describes it similarly, but I didn't find it. (I found stuff about plastic surgery, though).

I tried going through my memory to find words that are related to facial expressions or something like it, like frown, grin, smirk, snicker, pucker, stare, glare, wince, and grimace, but none of them really fit. "Frown" is close, but it mostly connotates anger or sadness. I'm looking for curiosity.

Then just now I found this page with a list of 100 facial expressions. I've just skimmed it, but it seems to me that the words in the list are mainly feelings, and not facial expressions themselves. I also found this Wikipedia article about Facial Expressions, but I haven't really read it yet, because I've been busy writing this blog post. I'll update this if I find it, but until then, I'm trying to find a suitable temporary replacement. I was thinking of "frince", or "fringe", but they both seem to be taken. Frince is slang for "fucking price", and fringe seems to mean boundary or something. It has to have a soft consonant at the beginning, I think, followed by an "r". The "r" would connotate some kind of force being applied, but in a good way, slight and controlled - in a curious, intrigued manner. "D" or "F" seem like good starting consonants. Yeah... "C", "T", and "P" are too harsh. "N" maybe? Nourl. Hmm. Too cat-like, and ambiguous pronunciation, so no. Hmmm. "Mirate". Hmm... sounds more like something related to what you are looking AT, not so much about your face itself. "Drince". "Dringe". Dringe. Hmm. Dringe. Dringe doesn't sound too bad. I'm sure there's better ones, but that'll do for now.

I dringe. You dringe. He/she/it dringes. We dringe. They dringe. Thou dringest.

I dranged yesterday. I will dringe tomorrow. He is so drunged.

I think the "i" vowel helps. It makes it sound harmless, small, personal, which I think befits an intrigued movement of the face.

But if you know what the actual word is for it, please tell me.

P.S: I found another word for a facial expression: Gurn. You should take a glance at it.

UPDATE: My dad just gave me a word to describe the expression: "quizzical". He looked at me quizzically. But it's either an adjective or an adverb, not a noun or a verb. But it does transmit the description quite accurately.
