Anyone received blue light therapy-felt nothing during treatment

I received BLT and didn't feel anything on my face- a remote warmth on one side. I have a friend that says he feels tingles and stinging plus warmth. My Doctor said I am one of the few that it work on. I did the hour with the serum and then 16 minutes under the light.
I told the tech that I didn't feel anything and she said that was fine.
Is this normal? I ended up having to put a cream on my face for 2 weeks twice a day. Turned the whole process into an endurance test!
But I don't think the treatment was done right. So wanted to hear if anyone else had this issue. Thanks in advance!
