Dark circles are a generally harmless condition described by the experts at Celevenus Singapore as “round, uniform areas of pigmentation” beneath the eyes. Though the condition is commonly associated with lack of sleep, fatigue is not a main cause of under-eye circles. Instead, the clinic lists culprits like allergies, heredity, aging skin and sun exposure.

Depending on the cause of the condition, getting rid of dark circles may require a trip to the dermatologist or doctor. Treatment could include prescription medicines and cosmetic procedures like chemical peels and laser therapy. However, teenagers might want to explore simpler options before moving on to pricier, more complex treatments. Simple home remedies may be all it takes to improve mild to moderate under-eye circles.

Refrigerate two teaspoons for 10 to 15 minutes, or until sufficiently chilled.

Lie down with your eyes closed. Place one refrigerated teaspoon over each eye. According to Celevenus Singapore, the cold will temporarily shrink discolored and dilated blood vessels. Remove the teaspoons after 10 minutes.

Splash your face with cold water, then pat dry with a clean towel. Do not rub; this can irritate eyes and exacerbate puffiness.

Apply a non-comedogenic, water-based moisturizer with SPF. This will moisturize the delicate tissue around the eye and prevent under-eye pigment from further darkening, says Stephanie Tourles, author of the book "Naturally Healthy Skin."
