I noticed a small oval shaped mark on my jaw 8wks ago, it was light pink in colour, slightly raised but not much, not bumpy or painful, sometimes itchy but not often. After a week, it became dry and then a scab formed and fell off. Underneath the skin was light pink again. It remained so for a further 4wks and then 2wks ago it became dry and scabbed over again. It has now gone back to being pinky/purple like a bruise. I used Fusidin (hydrocortisone/Fusidic acid) cream for 5days but it did not do anything. Any advice? I have not had any recent trauma to my face, it's not a bite, impetigo or contact dermatitis.
