Hi young Sea Hurricane Seany,this forum has been freckling aroundquite a bit in the past if you 'search':http://www.thenakedscientists.com/forum/index.php?topic=5094.msg42444#msg42444Quote from: Becca Priddy on 16/08/2006 05:55:42as 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?becca Quote from: neilep on 16/08/2006 13:43:44This 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.neil<font size="1"><font color="blue"> Men are the same as women, just inside out !</font id="blue"></font id="size1">Quote from: iko on 17/08/2006 18:10:39I'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.byeikodo you want an expert opinion?
