Dr. Pen M8 Needle Heads. Replacement Needles for Dr. 
Pen M8. Micro-needling is a safe, chemical-free, and 
minimally invasive technique for stimulating collagen 
production. Collagen and elastin give skin its texture, 
structure, and appearance. But as we age, these 
compounds break down from the sun and environmental 
damage that causes dry skin leading to wrinkles.
