Under eye circles are from excess pigmentation of the skin or shadowing from eyelid bagging. It is easy to tell what is causing your circles, simply by stretching the eyelid skin between your fingers. If the circles disappear, its bagging. If they remain, you need Scarguard Lightening Serum.
If the color stays when you stretch the skin between your fingers, you need to look carefully at the color of your eyelid circles. If the color is blue, the color is from blood vessels and no creams will help. This type of eyelid circle is best treated with Lasers. If it is brownish, It is called hyperpigmentation and Scarguard Lightening serum should work wonders.
Your skin cells make a pigment called melanin. The amount of melanin in a person's skin determines their skin tone. Hyperpigmentation means that the area has made too much melanin, and does not blend in with the surrounding areas. Many things can cause hyperpigmentation, including excess sun exposure, sun damage, hormones, illnesses and trauma.
