if your main problems are your eyes/browbone it’s probably not going to do as much as you would like, and will in fact emphasize them

I don’t think you will look like a femboy (??) I wear a face mask most of the time to hide my moidface

do it, its good for fragile ppl in closed spaces, helps a bit with dysphoria and social anxiety (from my pov ofc)

I dont think most femboys wear a mask to hide their face other than to post porn.
