Different preparations (cream versus gel) and their properties help determine how long your provider leaves the numbing treatment on before injection, Usually, the longer the better. Ice is also a great addition to help decrease pain and bruising.

I hope that this vide response that I've put together, answering this question is found to be helpful.

Hi, thanks for your question. Yes, in most cases if the numbing cream is left on longer it should have more of a numbing effect. Typically, getting lip filler should not feel painful. Some patients may find the sensation a little strange but not painful. Please speak to your provider if you have any concerns about your lip filler treatment.

Yes, numbing cream helps to make lip filler treatment more comfortable. The longer it is left on, the more the numbing will be in effect. If a Juvederm XC product is used there will be a numbing agent mixed in with the filler as well.

Thank you for sharing your question. In most cases yes, the longer the cream is on the better the numbing. In most cases 15 minutes or longer may be required.
