i usually used gel nail polish on my toes and have had no problem for years. last time i toile off my set i was left with this. is it a greenie? fungus? something else? what do i need to do to let it heal? i’d love to keep wearing polish (especially gel) if possible, i spend a lot of time at the beach and i don’t want to have one unpolished toe :/ is there also any idea of the timeline of the healing process??
