Wrinkly fingers on one hand?

[myhobbyisouting]

Why would I have wrinkly fingers on just my left hand? Has anybody had this?

They look clearly wrinkled whereas the right hand is fine

It's like I've suddenly developed "old" fingers. I'm in my early 40s so maybe I should've expected this but it was fine last week

I have no idea but initial thoughts - do you travel as a passenger a lot and put your left hand on the 'windowsill' of the car? Lots of people who driver for work say they've aged more on their right side.

Do you sleep in your left hand in some way?

In the bath do you have your left hand in the water most of the time and the right out of the water holding your phone or book or something?

Do you moisturise your face and/or body using just your right hand?

I was also going to suggest maybee you have it I the sun more inadvertently OP but maybe it's just dry? I'd give them a soak exfoliate and moisturise and see if that changes anything.

I hold my phone in my left hand. I wonder if it's that.

Don't drive/travel as a passenger enough for it to be car related. Very strange indeed.
