The flare comes back because the fix is in the wrong place
Creams work on the surface. Your immune system overreacts on the inside.
Think of your body as a cup. When your gut is leaky and inflamed, that cup sits at 70% full before you even start your day. One hot shower. One stressful meeting. One meal. The cup spills. That's the flare.
The answer is not avoiding what spills the cup. It's emptying it.
