Dark under-eye shadows (sub orbital hyperpigmentation) are the result of enlarged or swollen blood vessels beneath the thin under-eye skin. Lack of sleep, poor nutrition and exposure to damaging environmental conditions may all contribute to this frustrating condition. While taking care of ourselves by drinking enough water, getting plenty of sleep, etc. can help this condition, some of us may require additional help. Shadowfade is designed to do just that by helping to diminish the appearance of dark circles under the eyes. For additional help with under eye problems see our Firming Eye Gel.
