Skin rash on face

From time to time I develop a skin rash for want of a better description on my face. I get red lines running out from the edges of my mouth to my chin (approximately mutton chops shape) and the skin along my chin becomes extremely sore, itchy, dry and flaky. This occurs quite suddenly. I moisturise heavily and it usually goes away within a week or two. See attached photos.
The first time it happened, I had just returned from 2 weeks in Africa during which I had excellent blood sugar control and put it down to the Doxycycline anti-malaria tablets.
This recurred last week. I had experienced very good blood sugar control for over a month since I had been working and very active. At a party in my honour I had a jam doughnut and other sweet stuff, which of course I know I should not have eaten. It flared up almost immediately.
My current theory now is that it is diabetes related and occurs if I have a sudden increase in blood sugars after a period of good control.

I would be interested if anyone else has had a similar experience and any tried and tested treatments.

Of course - if my theory is correct, I know how to avoid recurrence.

Hi @nolly53

Hence if this happens I treat immediately with Diprobase cream which will restore it to good health within 2 days.

Thanks. I think that one of my kids may have Diprobase. I will give it a go.

Despite having been diabetic for 10 years before this happened for the first time, the first occurrence was after returning from Africa to a roasting summer here. I know that doxycycline can trigger skin rashes so it assumed that it was the cause - perhaps it did trigger it. Every other occurrence has been in the summer so this is the first time that it has happened in the winter. That is what made me think that diabetes may have been the cause.
