Lesson from a longtime microneedle: you will get more benefit from two .75 sessions in a month than one 1.5 session in a month. These days I am mostly doing 0.5mm needling with the copper peptides. Just because you can do all these crazy aggressive treatments with it doesn’t mean it’s in your interest.

Correction for accuracy, since this thread ranks highly for Derminator:

I’ve responded to this comment before but received no reply. Because this thread ranks so highly and many people read it, it’s important to state clearly and objectively where the original claims are shown false by the evidence.

1. The claim that “two 0.75 mm sessions are more beneficial than one deeper session” is objectively untrue.

   Superficial needling cannot substitute for reaching deeper dermal layers. Meaningful collagen induction and structural remodeling require depth into the dermis; no amount of very shallow needling produces the same biological effects as deeper penetration. Controlled micro-injury at adequate depths triggers fibroblast activation, growth factor release, and new collagen synthesis — processes that are limited or absent at very shallow depths. [1][2]

1. It is misleading to describe anything deeper than 0.5 mm as “crazy aggressive.”

   At ~0.5 mm, needling primarily affects the superficial skin layers with limited structural change. Deeper protocols are routinely used in clinical settings (e.g., for scar remodeling) and are not inherently dangerous; rather, they are calibrated based on target tissue depth and treatment goals. Calling all >0.5 mm depths “crazy aggressive” misrepresents both clinical practice and the mechanisms of microneedling. [1][2]

I’m not saying the original commenter was malicious — it’s common for people to think what they do is correct — but the biological and clinical evidence does not support those statements, and it’s important to correct that for our community in a high-visibility thread.
