When the weather is really hot I happen to get this (pinpballs not sure) around my lips, kind of like herpees but its not, what can it be?

Lip pimples? Some people develop lesions along the border of the lips when sebum accumulates and clogs up the sebaceous glands. Avoid manipulating the area to try to "pop" them. You could develop an infection or end up with scarring. See a dermatologist for tips on preventing these, or an aesthetician for extractions.
