Ever since childhood I have had small spots on my upper arms, which produce a hard white substance when pressure is applied.
I have tried every possible 'cure', including drinking lots of water, exfoliating daily, not moisturising, different kinds of moisturiser...
I have been told in the past these spots are the result of excess protein in my body.
I have reached a dead end.
Can anyone help me?

I have the same thing.
My mother says its from eating fats.
But I've been excersicing daily and they still appear.
