Depending on the type of ink, you might try oil-based hand cleaners such as Goop or acitrus-based solvent, or an alcohol-based solvent, such as isopropyl rubbing alcohol.
Though it's very hard on the hands and can damage clothing, dilute bleach works for ink-jet stains.

You can try using some removing it using certain alcoholic products such as alcohol wipes, nail polish remover, paint thinner.
However stronger product such as the pain thinner is not as recommended.
Nail polish remover or the alcohol wipes are the best choice though if you have.

I tried all the suggestions
but I did not have any luck.
I looked at the toothpaste and thought why not.
It was minty crest.
I don't know it that makes a difference.
Put it on the ink, got my nail brush all the ink came off.
If you don't have a nail brush use a toothbrush.
Good luck.

This might work: Try hairspray.
This is said to leave stickiness, but it works.
Any alcohol based products, even hand disinfectant.
Finishing with a soap rinse works to.
Dishsoap.
This works pretty good, but the thick ones meant for extra cleaning.
Using nail polish remover works, but make sure to wash your hands afterward really good.
Additional Info Mixing soaps you use with salt or baking soda to make a exfoliant like scrub works.
Also, trying baby oil may work.

A product called Amodex is a favorite among fountain pen users and it works on a variety of inks.
It was invented in the 1950s by a printer and was specifically designed for safe use on skin (its base is lanolin).
For use on fabrics, though, one of the Carbona " Stain Devil " spot treatments may be cheaper.
There are nine different formulations and the directions differ subtly, so sure to read carefully.
Stain Devil #3 is the one optimized for inks.

A Mr. Clean Magic Eraser (dampened with water) works very well, and isn't hard on the skin.

Sometimes I'll be working with stamps, and stamp ink is sticky and hard to remove. 

Even after trying lots of soap, body soap, scratching against a table, and sandpaper the ink still remains on my hands for a day. What can I do to get rid of the ink faster?
How do I remove hard-to-remove ink from my hands?

There are a wide range of products that you can use to remove hard-to-remove ink from your hands, depending on what you have available. You could try oil-based hand cleaners, a citrus-based solvent or even toothpaste. Nail polish remover and alcohol wipes are also worth trying, and a product called Amodex is designed for removing fountain pen ink. A Mr Clean Magic Eraser also works very well if dampened with water. The options are cleaners like Goop, citrus-based or alcohol-based solvents, toothpaste with a nail brush, hairspray and soap, Amodex or Carbona Stain Devil.
Try oil based hand cleaners like Goop or a citrus-based or alcohol-based solvent. Dilute bleach works but is hard on hands and clothes. Use toothpaste and a nail brush. Use hairspray and rinse off with soap. Use Amodex for the hands and Carbona "Stain Devil" for clothes. Use Mr. Clean Magic Eraser (dampened with water).
