How do i say you put a smile on my face in french?

There are a few ways to say "you put a smile on my face" in French, depending on the level of formality and sentiment you want to convey:

Formal:

* Tu me fais sourire. (You make me smile.) This is a simple and direct way to say it.

* Tu as mis un sourire sur mon visage. (You put a smile on my face.) This is more literal and slightly more formal.

Informal:

* Tu me fais sourire aux lèvres. (You make me smile.) This is a bit more endearing than the first option.

* Tu me donnes le sourire. (You give me a smile.) This is a more playful and affectionate way to say it.

More poetic:

* Tu illumines mon visage de ton sourire. (You illuminate my face with your smile.) This is a very romantic and poetic way to say it.

You can also choose to use the formal "vous" instead of "tu" if you are speaking to someone you don't know well or in a more formal setting.

Ultimately, the best way to say it depends on the context and the relationship you have with the person you're talking to.
