With rosacea, as you know, the skin is hypersensitive. Redness and bumps and tiny pimples and splotches, All come with the territory. I am assuming that you have oral HSV? If that’s the case, it’s more than likely to surface around the mouth and not the cheeks or other areas where rosacea frequents. Not to say it’s impossible but more unlikely than likely. If these pimples are little whiteheads, not herpes if the bumps that you see and feel are under the surface of the skin, not herpes. You can’t really spread herpes around. If you’re having an outbreak, for example and you put some cream on it to numb it or to help with healing, like an antiviral cream, you’re not gonna spread it everywhere. Herpes likes to emerge from thinner skin and it also needs to be transferred to thinner skin. That’s why something like sitting on the toilet, is no risk. The skin of the but it’s just too thick for herpes to penetrate. That’s like the skin on the cheek it’s too thick for a virus to penetrate unless there’s some huge open wound.

Maybe your skin is just more hyper sensitive right now. Maybe you’re under more stress and the rosacea is coming out full force. Maybe too much sun. I honestly don’t know enough about rosacea to really say what could be causing it. But I don’t think herpes would be on the list. Still it would not be hurtful to go to the doctor and have them take a look.
