      community Best Microneedle Lengths To Stimulate Stem Cells

      in Microneedling  18 upvotes 2 years ago
      Microneedling with needle lengths of 1.5mm to 2.5mm to stimulate hair follicle stem cells for potential hair growth. Using needles longer than 2.5mm is not recommended due to risk of puncturing veins in the scalp. A dermastamp is suggested over a roller.
