5 Frequency Separation

This command enables you to improve skin by editing tones without damaging delicate textures. Merge a copy of all layers with Ctrl/ Cmd+Shift+Alt+E, then go to Filters > Frequency Separation. Choose an amount that blurs out the skin, then click OK. Now highlight the low-frequency layer, grab the Clone Tool (set Sample to Current Layer), and clone to smooth out areas of blotchy skin.
