I’m getting fingerprinted to get a substitute teacher job, and I have to go back because the FBI rejected my fingerprints the first time around. These are grooves that go the length of the finger.
Anyone else have these? Any ideas on how to make my fingerprints come out right?
I have those as well, mostly between the joints but also a few extending past the 3rd knuckle of my pinky fingers.
I would expect that if the same wrinkles show up in the second set of fingerprints, they’d decide that that is just what your fingerprints look like. Trying to make them “come out right” seems counterproductive if any fingerprints they find aren’t going to match the “fixed” fingerprints.
The word you seek for that is desquamation.
You might try drinking extra water and more hand lotion for a day or two before getting fingerprinted to plump your digits. Its so easy to be even mildly dehydrated, especially in winter.
The skin on your hands is a good barometer of your body’s hydration level. Check out this article for more info.
About 90 minutes before the prints are taken, eat a bag of potato chips and drink a glass of water. then another glass of water every half hour. An easy way to check is to look at your tongue in the mirror. If there is a crease down the center of your tongue, you are not fully hydrated. Eat something salty and then drink 8oz of water every half hour until your tongue is flat and smooth.
At that point, if the prints are still wrinkled then that’s just what your fingerprints look like.
Actually it’s maceration, which describes the process of keratinized skin becoming hypersaturated with water. Desquamation describes how keratinized skin is shed.
Ignorance fought!
I thought maceration was grinding something up. I heard about it reading about chick culling 
I have those lengthwise lines on my fingers now that I’m old. Haven’t been fingerprinted lately though.
That is one definition, but not the medical usage of the word when applied to skin.
TruCelt: I don’t think I ever don’t have a groove down the middle of my tongue. Now I am concerned.
Qadgop: so where’s the line between bathtub wrinkles and trench foot?
Maceration is also used to describe soaking fruit to hydrate it or just kind of get the juices moving in and out.
So I guess that means you should soak your fingers in rum and sugar 
So I did get my fingerprints taken, but it wasn’t the wrinkles that were causing a problem.
According to the person taking my prints, the grooves are worn down, from being a programmer for so long. She sees this in typists, data entry people and programmers a lot. Also nurses.
Interesting.
I have those grooves too, more pronounced on my right hand . . . and they even extend onto my hands in some areas. I never had them when I was younger.
