Does a steady-looking candle flame flicker at a faster rate than we can see?

hello,I'm not sure if this is the right place to post this.
anyway here it is.
does candle flame always flicker?
i mean even if we see candle flame is steady does it flicker and change continuously(our eyes are not sensitive to see that kind of flicker)?

The flame is the combustion of a region of vapors of organic molecules that surround the wick. The flicker is the air turbulence blowing around the region of vapors into irregular shapes.
