How should I manage keratosis pilaris?

It's an elementary school child, and I guess you could call it goosebumps?

The skin on my arm is bumpy.

I looked it up and it seems like keratosis pilaris; it looks like this is hereditary.

My husband is like that, though. Both of his arms are like that.

It seems the daughter has the same skin as her dad.

I suppose men would be self-conscious about it too, but I'm a woman and my skin is like this...

My child is still young so I don't have any particular thoughts about it, but I'm the one who's more worried.

How should I take care of this?

I wonder if moisturizing well will suffice... or if exfoliation is the priority.

If I manage it well, can I get rid of it completely?
