It looks like one of the lichen “diseases” although its not contagious. It doesnt really need any treatment as it should clear up on its own…although it may take several months. The way you are treating it is fine, but do see a doctor if it becomes troublesome. Have you had any vaccinations recently? Sometimes occurs after vaccinations although usually in children..
Thank you. I’ve not had any vaccinations recently, last one was my covid booster in September 2022.
