Is any of this happening now?
Call 911
These changes usually do not require an emergency department visit, but they should not be postponed for months.
A dermatologist or primary care clinician can determine how quickly the area needs evaluation.
Emergency care is rarely needed for an age spot.
Seek emergency help after a treatment if you develop trouble breathing, swelling of the face or throat, a serious eye exposure, or signs of a severe burn affecting a large area.
Other emergency signs, for anyone
Someone who is struggling to breathe, gasping, choking, or cannot get words out
Someone who has chest pain, tightness or pressure lasting more than a few minutes
Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
Someone who is unconscious, or cannot be woken
Someone who is bleeding heavily and it will not stop with firm pressure
Someone who has had a seizure that will not stop, or does not wake up afterwards
Someone who has lips or skin that look pale, blue, grey or blotchy

Does any of this apply?
Book an appointment
A spot that has been examined and confirmed as harmless usually needs only routine observation.
Check it occasionally for changes, and continue sun protection.
Taking a clear photograph with the date may make gradual changes easier to recognize.
Arrange a routine appointment if you are unsure what a spot is, if you want cosmetic treatment, or if a treatment causes persistent irritation.
