Ode to Toilet Paper

Dear Toilet Tissue, 


I was noticing on your packaging that you tout that you are "hypoallergenic" and "dermatologist approved".


Does that mean some toilet paper is allergenic and dermatologist deplored?
Do I really need to start reading labels on my TP? 


Warning: This paper made out of peanuts, pet dander, and/or rag weed.


Warning: This paper made at a facility that may also process stinging nettles, poison ivy, and itching powder.


Thanks for stating the obvious, 
Lark
