Can anyone tell me what this skin condition is please

[Travelcrazy]

This sre my friends arms, he is 74 and always in the garden pottering around.
He has all these white patches on his arms and legs. It doesn't bother him but is it anything to be concerned about?
Thanks for any help.

Vitiligo?

It's vitiligo

My daughter has something similar when she tans and it's down to picking at herself. So scars in effect. I have similar to a lesser degree.

Idiopathic guttate hypomelanosis

Very common as you age, and harmless.

@Okayornot is there any treatment that works for this?
thanks for all your replies

If it is IGH then it is just the product of having older skin that has been in the sun a lot. As it isn't harmful I doubt the NHS would treat it. I would suggest he see the GP in the first instance so they can rule out anything nastier.
