A dermaroller is an instrument that creates micro pathways in the skin for products to better penetrate. It’s a great way to get your products to absorb and penetrate the skin. And also the dermaroller creates tiny pricks around the skin and gives enough space in between so the wound healing response takes over. You grow new skin. That, in turn, leads to a smoother, more even, and plumper complexion. Plus, when used in conjunction with a serum, it boosts ingredient absorption by up to 90%.
