Title: freckles from the sun?
Post by: Becca Priddy on 16/08/2006 05:55:42

as an arizona native i have thought about why people say that the sun causes freckles.. i was wondering if this is really true, and if it is does it have any purpose? or is it just a reaction our skin has to uv rays (or something else?) is there any evolutionary advantage to this?

This is a great question Becca !..I haven't an answer for you though ! [:)]...and would like to extend warm greetings to you.

I have freckles...as does my daughter...and when I was 7..I unfortunately became terribly sun burnt on both my arms......upon healing I was left with very freckly arms !..not the whole arm...just the top bit from the elbow to the wrist..

..........When the sun is very strong I do find that the freckles seem more prominent.

Lets hope a passing freckle sun expert passes by and answers.

I'am passing by but I am not your expert.
I offer my simple opinion (I like simplicity).
Freckles seem to be common in white skinned people (red hair, blonde)that never get a proper suntan but tend to 'burn'. Most of the melanin available is in the freckle themselves, so freckles get a tan...and the rest burns.
By gradual and prolonged exposure to UV rays some people get a nice protecting suntan and much more tanned freckles.
I knew it like this.

We should use a cream to remove those freckles.

We should learn to love diversity.
