Sen2cor: Correction without results

Good afternoon,

I opened the original image (band 2), I set the output image, and set the resolution: 10m. The appearance and the pixels values has not changed. =/

a question: the value of the resolution must be the pixel size of the band? 60m: 1,10 / 10m: 2,3,4,8 / 20m: 7.8A, 11.12

I appreciate if someone help!
