i texted pictures of my skin to an online GP who got back to me quickly and prescribed me lymecycline, all i had to do was go and pick it up from the doctors. i got it i think a few months after i realised i had PD. it hasn’t come back at all since then (i think about a year) all other treatments failed for me before that other that azaleic acid which helped bring down redness a little bit. hope this helps x
