Was not the magic blocking pen
I purchased this to use on my 16 year old son. He has acne basically on his T zone on his face and on his back. We used this pen on his face and did not seem to really notice anything that stopped temples but he did feel that they went through the cycle quicker then if he did nothing. I did not feel it did anything for him but he was happy with the perception it cleared up.
