Very useful in the cosmetic purse . . .
"The niacinamide and zinc in these wee beauties also help tone down any redness post pimple. I am not young, but still have oily skin and I find these incredibly helpful to have on hand. Hint: as soon as you feel a tingle of a spot starting, clean the area and slap a patch on as fast as you can. The sooner you intervene, the quicker it will go."
