I have had seb derm in the creases at the side of my nose for the last 15 years, on and off, mostly on. The doctors all prescribed steroid creams and antibiotic lotions, which worked temporarily. 2 weeks ago I decided to give apple cider vinegar a go. I stuck a clean q-tip in my bottle of acv and then applied to my clean skin, dabbing all the area around my nose that has the dermatitis. I did this 2x a day for the first day, then 1 more time on day 4. Then I gave it a break. The dermatitis cleared up on day 6 and hasn't yet returned. I no longer look like I always have a cold! The redness that accompanies the dermatitis is almost gone.
I figure I will apply the acv once a week for preventative measures. This is undoubtedly the best treatment I have tried thus far. If it stops it permanently, I will be thrilled. However, in the past the dermatitis flared up after consuming a lot of dairy products, so I always thought it was an internal condition... We shall see! I will report back in a month or so.
