MK II Penis oil acts on the local skin, and also on the inner layer
as well as the skin sub-layer.
The skin sub-layer is with capillaries and veins. Big Penis Oil acts on this layer of the skin from the outside in as it gets absorbed.
The penile spongy-structure tissues avert the Big Penis Oil from piercing into the core of the two penile cylinders.
It necessitates a harder erection for the Big Penis Oil to get into the core of the penile cylinders.
The vacant hollow spaces in the spongy tissues are the obstruction of the chemical diffusion (penetration) for the Big Penis Oil.
