Deal with Dark Circles
File this under "Sad but true": As we age we become more susceptible to dark circles. Melanin builds up under eyes, making skin appear saggy. The best treatment, say dermatologists, is an injectable filler like Restylane or Juvéderm (starting at $750–$1,000 per syringe). It pulls the skin taut, getting rid of the crêpey effect that emphasizes the discoloration.
