Diy Teeth bleaching results

[Lefort1234]

I did teeth bleaching with 45% carbamide peroxide and did 2 times 30 minutes, it isnt the best results I lowkey didnt do it perfect and it isnt hydrogen peroxide which is way more effective. And these are my before and after I only did like the front 8 on bottom and top.

Before:

After:

My question is should I do it again and how often would it take to get a really good result? Or is there a limit I am not 100% happy yet but its at least a little change in my opinion

Its btw the complete same lighting.

If someone wants to do it themselfes go on pneumos guides its in BOTB

Does anybody know a goo real peroxide source? On ebay I only found carbamide
