Maybe ask chemist for dakatort ointment it works for skins cuts etc
I don't know that daktacort is the most appropriate thing to be using on a cut, it's more for fungal problems or inflamed skin as its a mild steroid. Something like germolene or savlon would be better to ensure the cut doesn't get infected. Germolene also helps to numb the wound if it's sore. Try to keep it clean.
I think if it doesn't improve in a few days then maybe seek advice from a medical professional.
Edited to say, you're also not meant to use daktacort on broken skin, so definitely steer clear.
