Why don't you sell a 3 mm roller?

[SarahVaughter]

We don't sell longer needle lengths than 1.5 mm because they carry a risk of infection or nerve injury, especially if larger areas are rolled. And if even one needle is bent, serious skin damage and perhaps scarring will result. Bent needles are a significant risk with such long needles.



Our opinion is that 3 mm deep rolling should be only done by medical professionals.

 

  The necessity of rolling so deeply (with the exception of certain scars) is controversial as well.
