corns on toes

Help!
I have what I think are corns on the tops of my toes … mostly the 2nd thru 4th toes on both feet.
I’ve tried the over-the-counter corn remover and it doesn’t seem to work.
Are these something that a podiatrist removes, or do I need to see a dermatologist?
I’m trying to get rid of these things before summer sandal weather.
Thanks!
