How many lesions can be treated in one session, and how long does it take

The session length depends on the number, size, and location of lesions. A single lesion takes about 1–2 minutes of actual laser time; most sessions last 5–30 minutes including numbing and post-care. Multiple small lesions can often be addressed in a single visit when safely distributed, though the surgeon may split larger counts across sessions to keep healing manageable.
