The treatment of choice depends on the cause of the dark circles. If congestion or allergies cause the circles, treatment of the underlying condition should improve the dark circles. Eczema is a skin condition marked by redness, itching, swelling of the skin and inflammation. Skin irritants, allergens and stress can trigger outbreaks. Eczema can create the appearance of dark circles when it affects the area under the eyes, and rubbing under the eye can worsen the condition. If dark circles result from lifestyle habits, then improving sleep, reducing alcohol use, managing stress and stopping smoking can improve your dark circles. Laser surgery to lighten the skin under the eyes can be helpful when the dark circles occur because of irregularities of skin pigment.
