Biopelle’s Dark Circle Relief Cream helps plump up the under-eye area as it strengthens the capillaries to reduce future under-eye darkness. These dark circles can be caused by a variety of conditions – skin type, thinning skin, ethnicity, age, fatigue, nasal congestion, lack of sleep and allergies. This product also tightens the skin to reduce the appearance of shadows. It has light-reflecting minerals which reduce the transparency of the skin.
