It is common for skin to get dry and the condition is marked by less than the required water in the epidermis (the topmost skin layer). Males and females are equally affected by it. With age, the incidences for having dry skin increases. Elderly people tend to have less amount of natural lubricants and oil in the skin. Areas like the hands, lower legs and arms are more prone to have dry skin. Atmospheric humidity also affects the dryness of skin. It is called xerosic dermatitis or xeroderma.

It might be temporary and mild and may last for some days. In some cases, it can become a severe long-term problem. Dry skin symptoms encompass itching, discomfort and skin tightness. Winters and dry, cold air also affects your skin and the result is dry skin.

Why it normally occurs?
Individuals who wash or sanitize their hands more often can experience a greater degree of dry skin.

Medications may also induce this condition.
The epidermis layer of the skin normally has protein and fat, which prevents dehydration in the skin. When the fatty oils in the skin are removed, the moisture and protection of the skin is lost. The skin becomes more sensitive and breakdowns easily when it gets dried. It might cause the skin to become powdered or may be invisible.
Red rash may appear if dry skin is left untreated. Simple treatment and prevention measures have been effective in dry skin treatment.
Avoid chemical cleansers and harsh soaps is an effective way to prevent dry skin. Moisturisers and bland emollient application on a regular basis have shown effectiveness for treating the condition.
Cellulitis, bacterial infections and eczema might be complications arising from dry skin. Thankfully, dry skin generally is mild and the remedies are easy.
Generalised winter itching is also called winter itch and can be seen commonly amongst older people. It is mainly caused due to dry skin.
People suffering from eczema may also experience winter itch.
Cold temperature and low humidity can make the dry skin worse in winters.

Dry Skin - Why It Normally Happens?

It is a chronic autoimmune skin disease, in which the skin cells form a mass of scales. Usually, these patches of skin, which are dry, red and itchy, occur on the skin of the back, scalp, palms, knees, elbows and around the fingernails and toenails. But some people have the patches all over the body. The patches may also crack, flake and bleed. While there is no definite cure, the symptoms can be managed and treated.

Symptoms of Psoriasis

The symptoms of psoriasis may vary from patient to patient. However, if more than two of the following signs are seen, it is likely that psoriasis is the causative condition:

1. A sharp and localized pain in the joints accompanied by stiffness
2. Soreness in the throat
3. Tiny depressions in the nails or large brown patches under the nails
4. The diseased patches of skin can crack, peel and bleed
5. Swelling and tenderness of the limbs
6. Dental plaque
7. Muscle pain due to the swollen bands of connective tissue
8. A whitish and silvery mass of scales surrounded by red patches of stinging, itchy skin
9. The appearance of blisters or rashes on the dry scaly skin and also along the nails
10. Bumps on the folded skin like back of the knees, armpits etc.

Causes of Psoriasis

HIV
Human Immuno-deficiency Virus adversely affects the immune system and increases susceptibility of all kinds of infections and diseases. HIV-positive individuals have been found to have an increased risk of psoriasis than HIV-negative people.

Medication
Anti-malarial, anti-inflammatory and blood pressure medicines can cause psoriasis as a side effect. The disease is also an effect of withdrawal from topical steroid creams and other steroid-based medication.

Genetics
More than 32% of the cases of psoriasis have been linked to genes. In case of identical twins, if one twin has the disease,the other has a 70% chance of getting it too. There are several genes associated with the disease- most of these genes are related to the immune system. T cells (lymphocytes which affect cell specific immunity) can also cause psoriasis.

Other diseases
Diseases like strep throat, chronic infections, skin infections and stress may be responsible for the condition. Other factors like obesity, alcoholism, skin dryness and smoking can also lead to psoriasis.

Psoriasis: Symptoms and Causes

A skin tag is a diminutive, harmless, extension of skin that is usually attached from beneath the skin by a tiny support stalk. These skin tags are seen in places which are exposed to frequent friction with clothes or areas that have more skin to skin friction. They hang out from the skin surface. They commonly occur in the neck, underarms, groin, and upper chest. Medically a skin tag is termed as an acrochordon. Often skin tags are also identified as soft warts, fibroma pendulum, pedunculated fibroma, or soft fibromas. 

Reasons why they happen
Skin tags comprise of blood vessels surrounded by skin and loose fibers of collagen. Collagen is a kind of protein located all through the body. Anybody can develop a skin tag irrespective of gender and age, but elder people are prone to skin tags especially those who have type 2 diabetes. 
Skin tags tend to evolve in the layers of the skin folds, where the skin rubs against itself as mentioned earlier, but it is also observed that few individuals get skin tags without any such reason. This is also a reason why skin tags occur more in overweight people as they have more skin folds that are susceptible to chafing. 

Why should you get them removed? 
Most skin tags don't need treatment as they are harmless, but at times people do tend to discard them for cosmetic purpose or may be out of discomfort when they rub against skin or clothing. Checking with your physician in case you doubt the shape of the skin tag and suspect a cancerous element. In such scenario, you will be recommended biopsy for further proceedings if any. 

How is a skin tag removed?
A skin tag is removed through few procedures. Your doctor can consider any of the procedures mentioned below: 

 Cryotherapy: Cryotherapy requires chilling the skin tag with nitrogen fluid. Your physician may spray or swab a little amount of liquid nitrogen onto the skin tag. After the treatment, you may have a small blister which will heal by itself. 
Surgical removal: In the case of surgical removal, the skin tag is cut with a scalpel or scissors. The cut might sometimes be deeper in which case the cut will require stitches. Surgical removal has the advantage of obliterating the skin tag, but there is a risk of minor bleeding. Removal of skin tags doesn't require a full anesthesia. Local anesthesia is sufficient. 
Electro Surgery: Electro Surgery is another remedy where the skin tag is burned with electrical energy in high-frequency. The heat is applied through the narrow stem that holds the skin tag to the skin. 
Ligation: Ligation is yet another method where a surgical thread is tied up to remove the tag. 
There are also natural remedies, such as using lotions or essential oils over a period or also over the counter medicines but then a doctor s advice is always essential to prevent the scope of any scarring, to bleed or other such side effects.

Skin Tags - Get Rid Of Unwanted Extensions

Corns are small circular patches of thick, hardened skin that generally develop on the toes or soles of feet. They may occur anywhere else on the body. They might be caused due to friction and pressure which may occur, if you wear poorly fitted shoes or as a symptom of some other conditions such as bunions (big toe bent towards other toes) or hammer toe (toe bent at the middle joint).

Corns, especially on feet will not get cured unless its root cause is treated. If left untreated, the skin becomes thicker and more painful. Cures for corns will depend on the cause or nature of the corn. Here are some effective ways to treat most types of corns.

1. Removal of hard skin: A dermatologist can help remove the thickened skin with a scalpel, which will relieve the pressure on the affected tissue.

2. Products that treat corns: Some foot care products are specially designed to allow your skin heal and to redistribute the excess pressure that is causing the corn. These may be prescribed by your dermatologist for quick healing of your corns. Some of these products include:
a. Rehydration creams that soften thickened skin
b. Soft padding or foam insoles that can be inserted into shoes
c. Corn plasters that provide protection
d. Small foam wedges which can be placed between toes to cure soft corns
e. Special silicone wedges that change the position of your toes and help in redistribution of pressure.

3. Salicylic acid: Salicyclic acid, contained in several over-the-counter products is helpful in softening the first layer of dead skin, thereby facilitating its removal. Products containing salicylic acid should not be used if you suffer from conditions that cause circulation problems, such as diabetes, peripheral neuropathy or arterial disease. If you have cracked or broken skin in the area of the corn or sensitive skin, salicyclic acid is not suitable for you either.

You can prevent corns by practising proper foot care, as your feet carry the weight of the entire body and are very susceptible to problems. Using a pumice stone regularly to rub away hard, dead skin is a good way to prevent corns and bacteria. Wearing properly fitted shoes is a must to prevent corns. If you wear heels very often, they may put excessive pressure on your feet. If you suffer from diabetes or other diseases causing circulation problems, do consult a doctor as corns and infections in the feet can lead to more severe infections.

How to Treat Corns on the Skin

 Hives , also known as urticaria, is the outbreak of pale red, swollen bumps on the body. It can occur on any part of the body including the face, back, arms or legs. It is a type of hypersensitivity reaction in which the cause for the reaction is idiopathic (unknown). Also, it can come in various shapes and sizes. Hives can be associated with redness, itching, and a burning and stinging sensation. These can last for more than a minute or even more than that; up to days.

What causes hives?
Most of the times, hives are idiopathic, i.e. the reason that causes this type of hypersensitivity reaction is unknown. The bumps are caused by the action of histamine that makes the plasma in the blood leak out of the small blood vessels. Histamine is a substance that is released from a specialized cell and is what causes allergic responses in general. There are three types of hives- namely, acute, chronic urticaria and physical urticaria. Acute urticaria is when the hives last for less than six weeks. Chronic urticaria occurs when the hives last for more than six weeks. 

Physical urticaria refers to the condition when the hives are triggered due to causes such as heat, cold, sun exposure, sweating, pressure and exercise. Although, this condition is mainly idiopathic, there are common causes that may trigger this condition such as:

Foods such as nuts, fish, chocolates, milk and milk products
Environmental triggers such as pollen grains, dust etc
Medications such as ibuprofen or paracetamol
Insect bites
Latex
Blood transfusion
Bacterial infections including strep throat and urinary tract infection
Pet dander
Plants such as poison oak or poison ivy
What are the symptoms of urticaria?
Hives are usually self-diagnosable. The various symptoms of urticaria are:

Swollen red bumps known as weals
The red bumps can occur suddenly and subside all of a sudden as well
 Blanching which is characterized by the whitening of the swollen red part.
They occur on any part of the body and can change shapes, and sizes. It can become larger or it can reduce in size; it can also move around in the body.

Hives - Most Common 9 Reasons Behind It!

Dermatology is a very vast subject and many times it crosses the medical field to the cosmetology sector, where beautiful skin maintenance is concerned. The case of mole removal, for example, is handled by dermatologists. However, while examining the moles they first confirm that they do not, in any way, pose the risk of melanoma, a type of skin cancer. In fact, it has been reported that a dermatologist in Christchurch, New Zealand is offering free checkups during weekends for melanoma. Her plight is that she lost her brother to melanoma and many people make the mistake of ignoring moles on their skin and pay the heavy price.

A Professional Way Better than Trying at Home
For exactly the reason mentioned above, if you find moles on your skin, you should have the area examined by a dermatologist. The doctor would have the right instruments to identify and check whether they are only moles and then advise the appropriate removal. If the advice from the doctor itself indicates a simple procedure at home, then you can do this. There are over the counter products, such as peels available which can be used and then the moles can be removed. For other cases, you will need to subject yourself to a proper mole removal procedure.

Simple Methods For Surgeries
Chemical peels and burning away the extra growth using Cantharidin are some of the options available to dermatologists to remove moles from your skin. They may either have their own proprietary peels made or use the ones available in the market. Either way, the dermatologist will know how to prepare the skin before applying the remedy and also after treatment care. Skin is a very sensitive part of the body and no risk can be taken. If the mole removal has to be carried out only through a surgical procedure, the dermatologist will make that decision and do it as soon as you are ready.

Again, within the surgical method of removing moles, the doctor may use very simple procedures such as a scalpel to cut and remove the mole as well as a small amount of skin and dress it up. In the next level, the doctor may have to make a proper incision and then stitch up the area around the cut portion. Care will be taken regarding the scar on the skin.

Take Care of Your Skin
Depending on which part of the world you live in, there are steps you must take to protect your skin from getting damaged. In particular, the areas, like the face, neck, shoulders and hands which are exposed to the sun or cold winds or other vagaries that pose risks to the surface of the skin. The moment you observe signs of any abnormality in the skin, consult a good dermatologist to get healthy skin.
