What is the best treatment for under eye dark circles ? ( not a home remedy).

Are you talking about dark circles or ’‘bags’’?

The simplest remedy is sleeping and drinking a lot of water. The absence of those two cause the under eye dark circles.

Dark circles from genetics, the skin is darker there?
Dark circles from dark surface veins?
Dark circles from broken capillaries?

Get a Physicians Formula cover stick in Green, Blue, Lavender or Yellow. The packages will tell what skin tones work best with each color of stick.

Plenty of water.
Plenty of alcohol free sleep.
And..a clay mask applied under eyes until dry removes puffiness and shadows. :-)

Sometimes they’re caused by allergies.

If you go into Sephora, they will give you samples. You can try a few and see which work. Just a little hint, keep the names of the creams and remember which you like… I’m on the fourth sample and loved the first but can’t remember what it’s called! argh!
