I'm of the opinion that gloves are a solution for avoiding or limiting calluses, but with the asterisks that: 1) it can also be a (minor) crutch if not also developing your grip strength in tandem, and 2) that gloves must be properly fitting or else it might be even worse than no gloves at all.

If the calluses seem to relate only to isolation exercises, then #1 is less of an issue. But if they appear due to compound exercises, then that's a clue to improve your grip, as a callus ostensibly is due to uneven pressure around your hands.

For #2, ill-fitting gloves might grip the implement or barbell or dumbbell, but if the glove slides against your palm, then it'll bunch up and that virtually guarantees uneven pressure. You might also consider fingerless gloves, so that there's material only where it's needed to avoid palm calluses.
