That is pretty interesting that it just now changed. Do you know if the doctor turned up the machine or not? I see them more when the doctor is being more aggressive. Something you might want to try on the area is Triple Antibiotic Ointment. This is what I have used ever since I started laser treatments. I never get blisters and it makes things heal quicker then other things I have tried in the past.
I probably have not seen any recent pictures of Alexa. Send me one if you would.
Talk to you later.
