How would you treat indents on forehead caused by thickening and furrowing? (Photo)

I posted on here before thinking what I had was fat loss, but I finally found out the changes I'm seeing are from something called pachydermoperiostosis.

I wrote a whole blog about getting diagnosed for anyone who is curious: https://youmemindbody.com/disease-illness/it-began-with-a-forehead-indentation
