How to Reduce Rings Around the Neck

I have one and I'd love to get rid of it.  If you have dark rings around your neck, armpits and groin area it might be a sign of disease, so, See a doctor!  Otherwise, the ring(s) might be the result of skin stretching.  If you were recently pregnant, or lost or gained large amounts of weight that might explain it.  Bad posture and constant looking down are also said to cause these rings.  There isn't much consensus about the causes or remedies.  What you can do is try to lighten the dark lines by exfoliating and bleaching.  The skin on the neck area is very delicate, though, so be gentle and remember to apply moisturizer.

The following are some natural skin bleachers:
Yogurt.
Lemon -you can also mix it with yogurt and apply it, but it is photosensitive so stay out of the sun if you use it.
Papaya juice.
Shea butter -it's supposed to be highly effective in reducing the appearance of stretch marks and scars.
Vitamin E -ditto.

And, of course, neck exercises and proper posture should help as well.
