"Authentic Chinese Shops"I have tried China brush worked for the first few times...then stopped? Also comes in spray you can get at authentic Chinese shops.
An oxymoron unless you mean you bought authentically fake bullshit from an entire industry based on bullshit.!
As for it working at first, then then stopped working? Classic placebo effect.
You can't develop a tolerance to lidocaine, benzocaine etc. And there is NO mistaking an effective topical anesthetic. It FEELS numb to the touch.
