I’ve had it for 18 years 🤷‍♂️

[@user-tg5lu9gc1s]

Is it still there?

[@ReallyJustAnotherDay]

Approaching 10 for me. Cleared up on my arms still persistent elsewhere

[@ericmed]

@@ReallyJustAnotherDayDid you try using the sun or UV?

[@ReallyJustAnotherDay]

@@ericmed I believe its the sun which cleared it up elsewhere unfortunately its also somewhere which makes daily sun exposure illegal in most places! UV is apparently a really risky option there too and not recommended. Has yours persisted for 18 years no change?

[@ericmed]

@@ReallyJustAnotherDay Lately it's more on forearms, armpit area, chest, abdomen which is easier for the sun but to be honest I've been doing a pretty bad job with consistently getting UV

I have it since 2019

[@ReallyJustAnotherDay]

Light based therapy on genital Lichen Nitidus ever recommend?

[@fitzgn78]

My son was dx with Lichen Nitidus as he was getting lighter spots when he was young and 10 years later and he still has flare up.

[@dermatologyexplained]

It can be a tricky condition to manage, I hope the video has shed a bit more light and understanding on this condition

[@advanced8998]

It's caused by gluten! Tell him to stop eating gluten and watch it go away
