Again I am victim of a recurrent spur of facial seborrheic dermatitis. You see, that is the problem when you stop treatment for a couple of days - you just have to learn to live with it...
Seborrheic dermatitis on face is annoying and looks bad, but unless you control it it just keeps coming back over and over again. My affected areas are around the nouse, near the mouth corners, the chin, and the forehead. I've noticed that when my beard starts growing, the condition gets worse, and I hate that because I like to keep my goatee.
It is good to notice that I'm feeling a mild umcomfortable feeling on my face. I guess that's the consequence of drinking and smoking the night before - even once in a while, it affects your condition.

Insights on a Seborrheic Dermatitis Treatment on "Sew Many Things"

If you've suffered from SD (Seborrheic Dermatitis) for quite some time, you know how much of a struggle is to keep it under control. And yes - you can only keep it under control because this is a condition that can't be cured.
Not only that, to make things worse, doctors prescribe steroids that are known to cause side effects on the long term (like thinning the skin, and in some cases ostheoporosis). So, it is good to hear about how other people approach the treatment of SD without using potentially-problematic products. Take for example this detailed post about seborrheic dermatitis I found on a blog called "Sew Many Things". In it, Kira, the writer of the blog, talks about her new approach to seborrheic dermatitis.
I've already took some notes from the post! We are living in times when many of the so called "medical cures" only bring new conditions. Check out also her results photos. You can see the great improvement!
