Many experienced KP members have stated high CO percentages are very harsh on their skin. I have used as high as 30% CO because I like the lather qualities of this oil. I cannot see that my skin has suffered from this high percentage but I would like to know if I increase the supper fat from 5% to 8% or even 10%, would that offset the harshness of the higher use of CO? Would the higher supper fat diminish the lather?
