My six year old kid received a long thin scratch on his cheek about a month ago. It seemed to go pale, which showed against his natural skin tone, and I was worried it would not face more. I was recommended a cream ("Ella") and have applied it for about 4 weeks. I also used plasters during the day to stop the sun from getting to the scar (we live in Thailand and it is usually sunny).
The area it was applied to is now red and rough, and parts of the white scar line seem to have widened. I have stopped using the cream. What should I do next?
