What's wrong with my legs? Are they normal?

So when I was younger, around 9-10 ish, like usual girls that age, I was investigating and trying out a shaver razor for women's legs. Since I was that young and not supposed to be using it, no one had told me yet that with razors you need to shave them with moisturiser, shaving cream or in the shower.

So I just shaved my legs when they were dry and just normal.

afterwoods I got these red spots on the outside of my calf, from like my ankle around one third of the way up my shin. They didn't hurt, they just looked funny. They were flat and not raised, they were a bit dryer, but with some moisturiser they were normal feeling again.

Now that I am 13, I still get them, just when I am in the shower and out of the shower, when the weather is hot or when the skin has gone a bit dry.

It does not hurt, and thankfully in the past 3 years it has gone down to a more mild thing so it's less noticeable. The skin I think just feels like normal skin, its just tiny little round spots. They are flat its just like the pattern of the skin or something.

I'm just wondering what it it, will it eventually fade away completely, and yeah. I don't need a doctor, it's just a strange pattern of skin.

Also, when I'm in heat or the sun too long it goes quite dry and in really hot weather it looks like little flat scales.

(With moisturiser it looks normal again it's just a pain to put it on several times a day)

I'm not concerned, I just want to know more about it :)

Thanks :)
