I'm not sure if it's in syringes but it's not a 35% gel. I have some leftovers from what I bought from my dentist. I apply this on top and my dentist Opalescence 35% on the bottom. No comparison at all. None of that, not even a slight sting from accidentally hitting the gums. The light is good but I threw the gel in the bin and think I'll just pay a more expensive one from my dentist.
