One device that gets around that difficulty is the aside. An aside is a short speech from a character that is spoken directly to the audience. The other actors on set can physically hear the words but as their characters, they pretend as if nothing was said. The audience understands that the speech was meant for them only. History of the Aside
Lip burning sensation may also result from different types of lip burns or even chapped lips. Certain types of neuropathy (nerve problems) may result in lip burning sensation, as the cranial nerves from the brain supply the lips. Symptoms may occur in the lips alone or any other area of the body that is supplied by a peripheral nerve. Lip burning sensation may be the only symptom experienced, it may start as a tingling (paresthesia) and change to numbness, or there may be a combination of symptoms. Burns from heat, cold, chemicals and sun may also cause a lip burning sensation.
Just as the rest of your skin can be damaged by the sun, so can your lips. Yes, you can have sunburned lips, and they hurt! Treat sun damaged lips by applying aloe to help the burned skin heal more quickly. Use a lip balm with an SPF of at least 15.
