My final version of things that helped are this: with a cotton ball put on violet extract. let that dry. then put on calendula salve. I would do this both morning and night. Then when I got home everyday I would slather a combo msm/aloe gel all over my face, and pay special attention to the dermatitis areas. My face is now clear of any red areas, pimples, rash, all gone. This is what I recommend. I'm posting this under Violet Extract, as I feel this was the game changer. It took less than two months to clear completely.
This is my third post on Earth clinic on Perioral Dermatitis. I have been battling it for 6 years. As I had posted previously I was managing it by working to stay away from chocolate and sugar and trying to eat a green diet but recently had another bad flare (just after halloween! Had a few moments of weakness)
I discovered on another site people having success with violet extract. I got it on Amazon immediately. I put a few drops on the area and rub it in with my fingers. I have no side effects and it's starting to work. I noticed it works best when applied a few times a day. Its a little brown tincture with a light odor that goes away in a few minutes.
The first few days if the spot got dry and scaly I would use the Calendula cream.
I only started the violet extract a week ago so my problem is not gone yet, but it is much improved! I have high hopes. Will keep you all posted.
