Dairy is the worst thing in the world for my acne as well. I haven't drank milk in about 8 years because of it, even though I love milk. I don't take tablets for my skin and try to control it with my diet, but the amoxiclav I was given post-surgery completely cleared any residual acne that I had.
When I spoke to Zarrinbal about post-surgery foods, he told me to try and avoid milk and yoghurt because it leads to an increase in bacteria which might trigger an infection. I guess that same bacteria is responsible for acne.
Also, as I said to Modigliani, the hip graft scar is quite high up and would definitely be visible in a bikini.
