Why was the FIRST-degree burn ^^^^FOAMY WHITE^^^^?!?! Was It Coagulation??!!?!?!?!?!?!?!?! Please Answer With Reasonable Responses!!!! Its NOT VASOCONSTRICTION or DEHYDRATION!!!!!!!!!!

No. Redness and PALENESS is the result of the different behavior of
capillaries.
There is a difference between paleness and whiteness.

Not in my case. I am very dark-skinned [literally as dark as an oreo
cookie]. My burn wound appeared white -- foamy white. It was NOT cold,
so vasocontriction didn't cause the color change. The wound was
unusually hot, extremely irritating and painful and FOAMY WHITE.
What caused this whiteness? I know it is NOT vasoconstriction! It
seemed like a first-degree burn. The skin texture and moisture content
didn't change much. There was NO _swelling_ at all!
Is it the coagulation of the epidermal proteins that causes the
'whiteness'? If not, then what causes
it????????????????????????????????!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?
I know for a fact that it is ^^^^NOT^^^^

The plate wasn't NEARLY hot enough to ^^dehydrate^^ my skin AT ALL.
Plus the duration of contact wasn't long enough to dehydrate my skin in
the burn region.
I hope my response didn't seem harsh. I was just trying to clarify that
the WHITENESS I am describing has nothing to do with VASOCONSTRICTION.
Unlike what you describe, the WHITENESS did NOT turn red at all. The
wound began to darken to my normal skin color after it healed.
I hope you understand.

Hmm, I wonder what would happen if all the proteins in my epidermal
tissues throughout my body were thermally-denatured completely but did
NOT form *covalent* bonds after being denatured.

photo evidence or fuck off.

Well, no one gave me any rational answer. Some told me it was
vasoconstriction. Others said it was dehydration. I know it was neither
vasoconstriction or dehydration. However, I *still* don't know exactly
what caused the thermal burn to look white.

This would be conclusive evidence of one of two things:
a) Nobody here knows.
b) Nobody here cares.
Either way, continuing to ask the same question again and again is
unlikely to generate new and interesting responses.

WTF?! I posted it to biology, medical, and chemistry newsgroups! They
should know and care, because my question involves biological, medical,
and chemical entities!

Did you ever post how you burned it?
Was it some caustic soda?
:)
Radium
No. I've said repeatedly, the burn was caused by contact with a hot
plate.

Sorry-my mistake. I forgot that you would be a much better judge than
I of what I am interested in. The fact that you haven't got the answer
you wanted after umpteen thousand repititions of the question must be
an experimental error, and not an indication that nobody cares.
So go ahead- ask the question again, and again, until you get the
answer you want.
What's that definition of insanity again? Doing the same thing over
and over, and expecting different results?

Call your doctor. You can pay him or her to give you an answer.

If that reply was directed at me, should I point out that the question
was rhetorical?
David Bostwick
Sorry. The suggestion was for the OP.
