3. Soothe Your Skin:
Truth is, cool temperatures naturally relax skin that is irritated or over exerted. So the real reason we always see people at the spa with cucumbers under their eyes is because they are the ideal shape to rest over the eye, plus they lock in moisture, (which perfect for replenishing thirsty skin).
Another way to go about this method is to place a cool, used green tea bag on the skin under each eye, feel free to use extra relaxing types of tea like chamomile, peppermint and lavender.
