Hi Skin Biology I currently have the 0.5 needling device and have been using it for several months 3 or 4 . My question is when would I know when to buy a fresh new one ? I needle every Sunday night .

Thank you for posting your question winter!

Our particular microneedling roller is best used up to 30 times.

It's nice that the container / box our device comes in has on the side a printed schedule where you can literally check off the times you've used your roller.

That way when you reach 30 times you know it's time to pick up a new roller.

Best Wishes,
-Skin Biology

Hi thank you I didn't know there was a spot on the case to keep track I will do this
