Listening this week could save your life (well, at least your kidneys).  Find out what common ingredient in keratin treatments you (and your friends, family and patients) NEED to avoid.  But there's a lot more than that packed into this week's episode.  As always, the Derms on Drugs bring the goods on the latest questions that the literature is answering:

-What is "transcutaneous auricular vagus nerve stimulation" and which common but difficult derm disease does it help with?  
-What OTC supplement makes NBUVB work better for vitiligo?  
-What oral drug can you add to isotretinoin to make it work even better?  
-Does oral tranexamic acid increase the risk of blood clots when used in dermatology?
-How well does Opzelura work for hidradenitis suppurativa?
-Do Humira biosimilars work as well as Humira in hidradenitis suppurativa?
-What common statistical technique used by pharma is total BS?
-Which ingredient in 'keratin treatments" is causing kidney failure and kidney stones?
