This photoshop tutorial will show you how you can adjust the flesh tones by removing the excess red easily.
Step 1.) Open your image, choose the lasso tool from your Tool Pallete (or press L) and make a selection around all the flesh-tone areas in your photo. You can add other flesh-tone areas to the selection by pressing-and-holding the shift button.
Step 2.) Go to Select > Feather (or alt+ctrl+d) and enter 10px
Step 3.) Choose Image > Adjustments > Hue/Saturation (or ctrl+U) ..When the dialog appears, click on the edit pop-up menu and choose Reds (you’re only adjusting red tones in the selected flesh areas)
Play around with the saturation and hue, to get your desired tones.
