There currently is no cure, but for comfort I recently read (possibly here somewhere in the Mayo Clinic Connect forum?) that coconut oil (the "hardened" form...like the consistency of lard/shortening) can provide relief for some.

I've been using prescription Clobetasol for years. Before that, decades ago, a form of a testosterone cream was prescribed. Fortunately I haven't had any issues with the Clobetasol at all. But everyone is different.

Another, but more expensive nonprescription option is Aquafor.

Do look into the online Lichen sclerosus society that may have some helpful advice & where others share their LS experience, & there is a weekly interactive forum on Saturdays. I haven't gone there much myself. I have found more community (& privacy) here on Mayo Clinic Connect.

I hope some of this may help. Let me/us know what you find helpful and hopefully provides some solace.

Best wishes.
