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.
