This is the first time I've ever had a real scab from a whitehead. What I've done is placed a piece of hydrocolloid dressing on it. These are basically big, medical bandaids used for larger wounds, but u can cut them to the size u need with scissors. I Got mine on Amazon, but there r also facial bandaids sold in stores. I use these for my red marks from previous acne and they work very well, but this is my first time using it on a scab. I'm sure I'll get goods results from it as well. Is it's completely flat or is there some swelling still? Either way, I'm sure covering it up well help it heal.
