First smartphones and now…. smart cleansers? A new hi-tech cleanser called Dr. Dennis Gross Color Smart Cleanser & Mask ($28) changes color when its ingredients are hard at work. Formulated with vitamin C to brighten, antioxidants to protect, and clay to absorb impurities, Color Smart doubles as a mask to detoxify, firm and illuminate dull skin. It deeply cleans pores while gently exfoliating away dead cells.

To use as a cleanser, apply the product onto dry skin and massage until the color has changed completely to orange. Once the color is different, that’s your cue to rinse. As a mask, simply leave the formula on your skin for three to four minutes for an extra deep clean. The change in color signifies that ingredients have taken effect.

To put it simply, this is like a cleanser for dummies — it’ll tell you when your face is clean but also if you missed a spot (hello, pesky hairline). Washing your face doesn’t get much easier than this!
