**Q: Can you use this in a micro needle vial, or is it too powerful?**
A: Per directions, apply this product to chin or neck to do a patch test to make sure you have no allergic or harsh effects. If not, I'm sure you can use this serum with the micro-needling. Anytime you perform the micro-needling it's very beneficial to have a serum to protect the skin from needle entry and of course to let your favorite serum penetrate the skin.
