What causes sun blisters on lips?
Sun blisters on lips and other parts of the body are caused by prolonged and constant exposure to harmful UV rays from the sun. Though common in those with a fair skin, the blisters can also develop in those with dark skin who spent a lot of time outdoors.

Sun poisoning blisters
Sun poisoning is defined as an extreme case of sunburn. Sun poisoning blisters occur when UV rays from the sun inflame your skin. In most cases, the symptom will begin similar to those of a normal sunburn. In some people, it may go on unnoticed leading to severe symptoms and dangerous situation.
The strength of UV radiation from the sun is determined by a number of things including cloud cover, closeness to the equator, and altitude. According to the WHO, small doses of UV rays can be helpful to your body, however, too much of it lead to premature aging and skin cancer.
Overexposure to UV radiation can damage your immune system. This can slow down its infection-fighting response. This is the reason when excess exposure to the sun can also trigger the development of cold sores.
Sun blisters vs cold sores
