The Cellex-C Skin Perfecting Pen is a leaf-green, pale, alcohol-free liquid gel that helps restore complexions by producing an environment inimical to the bacteria that develop on oily skin. This product also minimizes irritated and sore skin that is produced due to minor skin explosions and decreases the duration of breakouts. The Cellex-C Skin Perfecting Pen can also be used on insect bites for immediate cooling and soothing. It may also be used in conjunction with Retin-A. All ingredients are natural and herbal.
