Free Font in Adobe Products ?

Hello,

I would like to use photoshop's font to put in pictures I sell.

I would like to know if the fonts are free if I have bought Photoshop, or if I have to pay even if I have already pay the Photoshop program ?

I don't know if the fonts on my PC are free.

I thank you very much for the answers, and apologise my poor english : I'm french, and I forgot many words ! ...
