In all fairness, if she needs an antibiotic for the PD it can’t be prescribed by a pharmacist, but yes, people should use Pharmacists more than they do. They have a wealth of knowledge.
From experience, the fastest way to get PD is by damaging your barrier. I have noticed an increase in the number of people posting photos of PD-like rashes, asking what their rash is and then in the same breath advising us all that they’ve been triple cleansing and using 12 million acids daily. I’m only saying this as I used to follow Hirons’ advice as a University student a few years ago. I used so many acids/vitamin A products that I really damaged my barrier and ended up with quite a bad bout of PD.
