Hello,
Thank you for asking your query.
From the information and the images you provided, the lesion does not look like a Cold sore (Herpes Labialis). I am assuming that you have no other symptoms of like sore throat, itching, redness of mouth or slight itching of the area (to start with).
So this can be a case of simple acne or folliculitis. But there is a rare possibility that this is an early stage of Herpes labialis which may evolve to typical clinical picture. I would recommend you not to apply pressure over lesion. Wash using a mild detergent/soap/face wash. Use clean towel to wipe gently. The lesion should disappear in 2-3 days. If not you may want consult a Dermatologist.
Hope this helps
Thank you
