Question:
I'm using the skin colored cream as a semi-ok concealer for the scab. Unfortunately, I'm starting to get tingles in that area--has anyone heard that benzoil peroxide isn't good to use on cold sores?

Answer:
Can't vouch for benzoil peroxide though hydrogen peroxide is very healing, I'd skip the cover up and just use a small bandaid instead. I would think this would irritate the lesion more than anything. I find that my acne is more irritated than helped by that stuff (though it does clear up faster), and ruins my clothing too. Just my two cents.
