Start by steaming your face or using hot/ice cold compresses to open the pores and increase circulation. That's a long (and stressful!) trip with recirculated air, so your skin needs a refresher!
Rotate the hot/cold compresses (5 minutes each) several times. Then follow up with a nice aspirin exfoliation and mask. Just mix 3-4 plain aspirin in some water until it forms a grainy paste. GENTLY rub your entire face with the paste, exfoliating the old skin layer and exposing the new. Then just leave the paste on for 15-20 minutes, rinse with warm, then cool water.
Follow up with a green tea toner (black can also be used--green is best). Heat water, add 2-3 tea bags and allow them to steep on the counter for about 5 minutes. Put cup with bags into the refrigerator. When chilled, apply to your face as a toner. WONDERFUL for the skin, and really wakes it up! Don't rinse it off! Also great as a makeup base.
Try these and you'll see a quick change!
