Weird looking wound(s)
I have a wound on one of my finger joint(if that's the word). The wound is very very dry skin, and is only sligthly more red than the suronding skin.
At the border of the wound, there is a rim about 1mm tick made of skin. The finger hurt a little during uses. When in uses, sometime, the skin break
open and blood come out of it.What bother me is that the wound have been there for about a month and half. Three week after I saw it, it somewath
disapeared, but two week afterr it re-apeared. Few days ago I saw that on my other hand thumb joint, a similar wound appeared, albeit less severe.
I will take a photo in two hour or so.
PS: My face burns are less severe, and may be seen as .normal. teenager skin defect, but I do think I will be marked for life. Price of chemistry
hobby I guess.
I never asked for this.

Start using face shield and some good gloves so it doesn't happen again.

No, I don't.
It is a bit hard to see, but you can see a two day old skin shred, the pictures doesn't show the wound right.

I hope that the problem with your fingers is not due to some allergy. Some people become sensitized by certain chemicals. This can go unnoticed for
years and then suddenly, one bad day, the problem appears and from that day they never can handle the chemical compound again without severe skin
problems afterwards.
I do not say that your wounds are due to allergy, but it might be one direction to investigate. Did you have repeated exposure to some chemicals? Do
you have a concrete cause of the wounds, or did they apparently without reason appear?
Latex can be a source of such problems, sometimes the powder inside gloves. Another well-known sensitizer is hexavalent chromium. Some transition
metals (nickel, hexavalent chromium, cadmium, cobalt) are known sensitizers. The most serious ones, though, are many organic compounds, especially the
somewhat more complex ones. Stuff from oranges, kiwis and other fruits also can be sensitizers.
Another aspect of sensitization is that some sensitizers need an initiator to act so. Some organics may become a strong sensitizer, in the presence of
another chemical, while both chemicals on their own may be relatively benign.
Some people also can have wounds simply by frequent dehydration. I myself notice that if I wash my hands very often, then the skin becomes very dry
and in winter time this even may lead to little cracks in the skin. Annoying but nothing serious. In the past I had the habit to wash my hands
frequently during experimenting, just to be sure that no chemicals stick to my skin, but I abandoned that practice. So, if I experiment, especially
when it is cold in the lab in wintertime, I try to avoid washing and wetting my hands as much as possible and I only wash them when I have had contact
with a solution (e.g. liquid running along the outside of a bottle or test tube), and when I'm done experimenting, preparing for leaving the lab.

I only work with neoprene and PVC gloves. Repeated exposure, of course, sulphuric acid for example, and a lot of others. There a reason, maybe not
chemistry related, but it look like so, but I don't know from where they come. The wound look pretty deep, and I'm sure that if I take it and use
force it would shred my skin. I work with all what you said but cadmium. I never had dehydratation actually, and must say it is very weird to have
such a wound.

That looks somewhat like my eczema that comes and goes on my hands and fingers, especially the right one. This showed up about 5 years ago and won't
go away. My doctor said it was due to allergy - I said "from what?" - he said "I have no idea." I keep it knocked down with a prescription cream:
Betamethasone Dipropionate cream, USP 0.05%.
Dry weather and frequent washing makes it worse. It tends to itch.

Never seen an skin allergy like this, the wound is very deep, and much like a chemical burn, the skin rim would confirm that. It is like If I had a
vein(if that's the word) all around the wound. Look very weird, I hope it is not a sign of poisoning!
As for picture size, next time I will put a download link, will be simpler. I have hard time with cameras.

I'd take Woelen's advice on this one... Your pictures are just far enough out of focus that it's difficult to tell just what exactly that wound is,
but I've had similar things happen. I have poor circulation in my hands and feet (likely genetic, one of my sisters has clinical raynauds and the
other is somewhere between us), along with very dry skin when the humidity drops... Although I normally heal relatively quickly, something that would
heal cleanly in a week during the summer will take three to four and develop "rims" of scar tissue during the winter - The dryness coupled with lower
circulation is quite the double blow...
Take Woelen's advice here and avoid washing your hands if you can - If you must, use the mildest soap that will do the job, or just plain water.
Avoid contact with defatting solvents, basically any alcohols and anything non-polar, as they will literally dissolve the oils out of your skin and
dry it even further. And a better picture would help - You need to know if this is an allergic spot reaction, a rash, a chemical burn, or whatever to
figure out the best course of action.
If you see me running, try to keep up.

my 2 cents: Please consult a doctor. Could be that this is entirely not chemicals related. Keep an eye on it, and see whether more such spots appear
over the coming time.
Besides, if you use soap or other fat dissolving agents, the skin becomes more open to the absorption of stuff from outside your body, as it opens up
your pores. I completely agree with woelen, and use similar practises, i.e. wash with plenty of water, if really needed with a brush, only after
contact with chemicals/solutions. Soap and cleaning agents only after work is done.

What you have described sounds/looks like a fungal infection, most similar to "ringworm" (tinea, sp.).

A fresh idea Ozone. It does look similar to "athletes foot" that I used to get as a teen. try some anti-fungal cream for a couple weeks, maybe that
will resolve it.
I would of course consult a dermatologist if it persists. Good luck plante, and be safe.

Chemical-induced excema. ( I think, your pictures are shitty... and too big, shrink them) had this on my pinky many many years ago thanks to a few
drops of lead acetate solution.
In Canada a 0.5% hydrocortisone cream can be bought OTC. Put this on the rash, put a cotton glove on overnight and repeat for a while. It may
reappear for a few years when sensitized by environmental factors.

interesting.. seems as this might be what i had!? i had this damn thing all over my body (well ok.. 85%..)
i even had it long time after i was forced off chemistry for as much as 2.5 years and to this day i still have it (not that severe tho..
i now have it on my leg, i believe one tiny 0.5x0.5 cm mark on each arm..
dry reddish skin..
have you been exposed to SO3 or similar gasses? i cannot remember exactly when i first time met SO3, but it could be around the same time i started
getting these weird things.. doctor explained it as being ''dry skin''
it comes and goes as i noticed, using tonnes of soaps makes it worse and winther isnt good either
it forms some sort of white crisp on the surface that you can scratch off, and ofcourse it becomes pretty itchy after that where you will be left with
thinking it was a bad idea to scratch it off..

A few hours ago I washed some glassware, and one had a small amount of diluted H2SO4 remaineing on it. When I washed it, some got on my wounded
finger, a burning sensation was observed, after washing my hands, and a few hour of reading later, the wound disapeared and doesnt hurt!!! I'm all
mixed up, how can it have come from bleeding very tin sensitive skin to healty skin???
Very weird.

woelen "I hope that the problem with your fingers is not due to some allergy. Some people become sensitized by certain
chemicals."
Sounds like an accurate diagnosis. Possibly some contaminating material is still in the wound?
"Some people also can have wounds simply by frequent dehydration. I myself notice that if I wash my hands very often, then
the skin becomes very dry and in winter time this even may lead to little cracks in the skin. Annoying but nothing serious. In the past I had the
habit to wash my hands frequently during experimenting, just to be sure that no chemicals stick to my skin, but I abandoned that practice. So, if I
experiment, especially when it is cold in the lab in wintertime, I try to avoid washing and wetting my hands as much as possible"
I have dealt with this for decades and the answer is simple, keep skin moist with Aloe Vera and never get cold water on your hands. Wait until the
water gets warm. Most people stick their hands in the water while it is still running cold. Try it, you will see a big decrease in the skin cracking
problems in winter if you avoid cold water.

Maybe the H2SO4 indeed dissolved some sensitizing chemical and rinsed it away from the wound. Maybe some insoluble oxide, which now is removed?
Anyway, good to read that the skin is better now. Let's hope it remains so. Please report back on that after a few days.

Well, it either removed the substance that caused allergy or broke whatever it had inside leaving it normal. I wouldn't recommend the topical use of
H2SO4 though

But will it blend?
I'd recommend trying Aloe Vera if you haven't already - that stuff seems to cure everything around here...
