How often should I replace the needles on my micro needling pen?

Hi @Keekoh. Each tip is single use only. I recommend going to a professional to have this treatment done to avoid complications and infections. Best of luck to you, Dr. Nima!

Each tip on the (medical grade) pen I use is sterile single use only.  I dispose of it in the sharps container.  Hope this helps.

Thank you for your
question.Micro-needling needles should be replaced after every single use.

I hope this helps.To be sure, see two
or more board-certified providers in your area for a complete evaluation to
make sure you are a good candidate and that it is safe for you to have
treatment.
