When should I see a dermatologist about actinic keratosis? 

You should talk to a dermatologist about any changes you notice developing on your skin, but it’s particularly important if you have symptoms of actinic keratosis and notice any of the following: 

• the patch gets bigger

• the patch starts to bleed 

• the patch changes colour, particularly becoming red or darker

• the patch becomes sore or painful

• a rough patch develops into a raised, distinct lump

• a scaly patch appears on your lips

• a scaly spot doesn't go away on its own
