Dear
i have been seen some effects with a cream with (hypericum triquetrifolium) flowers you may know as st John worst (ypericum perforatum )
I mean it helps the symptoms.It makes the skin soft and clean if you use it twice a day (You must care very much ,do not have exposition to the sun . you can use it with no direct contact to sun in the area you apply
I do not know if it cure but i know it helps
With my best wishes
