Micro-needling & Needling Depth

A great advantage of using an automated needling pen is that I can adjust the needle depth to tailor the treatment to different areas of the face.

For a chicken pox or acne scar I can increase the depth to 1.5mm and penetrate to the dermis layer to engage the fibroblasts to produce collagen to treat the scar tissue.

There may be areas of sun damage, I would adjust the pen to 0.25-1mm to target the melanocytes that produce the melanin pigment that cause discolouration patches.
