So...in the right corner of my lips there is a darkened spot a discoloration. what is it? is it harmful? is it sunburned?

Venous Lake: What causes a venous lake to appear on the lip? Can it be removed without leaving a scar? An injury from a blow, bite or burn may damage the lip tissue and allow blood to accumulate under the fine skin on the lip, or any other part of the body. They are caused by the ruprure of a very small vein near the surface of the skin, while the skin over it remains intact. See your doc to make sure.

Many possibilities: There are many things that may cause a discoloration of the skin. Several types of inflammatory conditions of the skin, allergic reactions, and sometimes bacterial, viral or fungal infections and cancer can cause a discoloration of the skin. Insect bites can also be the cause of a rash or a discoloration of the skin. Have it evaluated by a professional and get the appropriate treatment.
