Talc?

Don’t use anything on the scar as it’s an infection risk. I use a sanity pad on my scar (placed inside my pants) to try and keep it as dry as possible x

You can get dressings on Amazon that you can cut to size, please don’t put anything on it until it’s healed. After a shower, I would use the cold setting on the hairdryer to dry off and whilst laying down apply a new dressing so that when I stood up it’s like under the overhang and did that until I felt it was nice and healed😊
