Welcome to HealthcareMagic. Hope you are sure about the fact that the fungal infection
is completely healed.Because generally infections of fungal origin take longer time to get healed , unless one has taken months(min 3mnths) of treatment. So in case it is still there, you better restart with antifungals like Terbinafine
or Miconazole ointments, offcourse after proper consultation with Dermatologist
.If you sure it is just a scar, I would suggest, take good amounts of Vitamin A and C supplements, and keep applying Aloe Vera over the area.It takes long, but effects are good.Take care.
