First, it is very hard to decide what a red mark is ,without seeing it in 3d, and really that means you must visit a GP.
A long term red patch is a result of a scrape or bump, or a burn, a cold burn
or exposure to a foreign substance.
Likely foreign substances are things like
* insect bites - mosquitos, midges, dust bird or cat mites, or bed bugs.. its not common but the lingering effect of a bite might turn into a large red patch after a week or so.
* plants - many plants have irritants in their sap, leaves,stems, and even flower or fruit.
This might also take a week to show up in full.
* chemicals - eg dishwashing detergents are corrosive, paint thinner or paint stripper, and so on.
There are skin diseases that are not caused by an external agents though.
Vitiligo, psoriasis, or otherwise a non-lumpy eczema .. The symptoms so far are not bad enough to be called psoriasis ...
The treatmeants for all are the same.. the skin is sensitive there, so keep the spots moisturised and don't expose them to chemicals or detergents.. even anti-dandruff shampoo can be too strong. Don't dry them out with long showers or baths.
Vitiligo is the symptom of unexplained de-pigmentation in patches of the skin. Vitiligo may be caused by ill-health.. eg malnutrition or lack of vitamin D (you can get vitamin D from certain foods .. or make vitamin D in your skin it by exposure to sunlight.). The patch of light skin may go red because without protection from UV ,and the patch is easily sunburnt. sunburn will then cause the colour to return to the patch, and also Tanning triggers the repair of the skin in general , so exposure to sunlight can be a cure for the spots caused by Vitiligo, psoriasis or any patch of eczema .
Suntanning can make conditions like acne and dermatitis worse.. so be sure its not an infection .
Sounds as if you might be allergic to the chlorine (or some additive) in the pool. Check with a dermatologist.
It is because they are a day walker and you are probably full on ginger.
you will get the red spots from probably if your skin reacts with either your soap or you body wash and the white blotches you will probably get from having prickly heat THANKS. I Tried changing the shower gel and the rash's still occured. can u help again ?
because when the sun hit's it it burn's and goes all red if you were talking about sun burn.
People get red when they are angry because its the contraction of skin muscle and nerves.And it turns to red because of stress.
because there is a natural reaction and your blood comes to the surface
Possibly a lobster- they go in dark blue and come out red/orange... prawns go in blue and come out pink.
They do what they do before they shed the skin. Look for food and hide in areas where food may come to them.
Have you ever scalded yourself with very hot water from the tap? Noticed how red the skin was? That's exactly what happens when you go into the sun without sunscreen - the sun burnsyour skin - and a burn is a burn. It is skin damage. You should always use sunscreen.
