White rash on hands

I have a white rash on both hands that is only noticable when you look closely (no one else has noticed but me).  

It is 'under' the skin and there are no bumps,  raises or dry patches on my skin.   The skin on my hands is perfect and smooth, this appears to be under the skin.     I have pink porcelain skin and the white dots under the skin are singular in some areas and in clusters in the other.    I do not think it is a loss of pigmentation as such as the dots/patches aren't big enough.

The soles of my feet are perfect.   I did have white lumps under the skin on the arches/side of feet going back about 5 years ago which have gone down - and was told they were lumpy fat tissue and not to worry about them.  

There are no other rashes on any area of my body.    I get cystic acne and lots of skin breakouts, but I have always had this issue since I was a teen.    I am 23 years old now.  

There is no rash on the tops of my hands.
