Soften Skin?

Get the Adjustment Brush (K) from the toolbar, and then click on the – (minus sign) button to the left of Clarity four times to reset all the other sliders to zero and set the Clarity amount to –100 (all the way to the left), and then increase the amount of the Sharpness slider to +25. Go ahead and paint over your subject's skin areas (avoiding things like the lips, eyes, eyebrows, hair, eyelashes, nostrils, etc.), and it softens your subject’s skin.
