Find out why cracked, dry skin happens and what you can do about it.

Dry or cracked skin can be a real nuisance, and you must be giving your skin the care it needs to keep it hydrated. You may find that your feet or hands are particularly susceptible to cracking and dryness, especially during the cold winter months.

What Is Causing My Dry, Cracked Skin?

Pay attention to your symptoms so you can pinpoint what might be causing your dry or cracked skin. Dry skin may be the result of,

  • Exposure to hot water (e.g., washing dishes; taking a hot shower)
  • Cold weather
  • Chemicals (e.g., laundry detergent; dish soap)
  • Medications
  • Eczema
  • Psoriasis
  • Athlete’s foot

How Is Dry Skin Treated?

There are many ways to tackle dry skin depending on what’s causing it and where the dry skin is located. Luckily, dry skin can easily be treated with certain home care, including,

Using a daily moisturizer

A moisturizer will become your new best friend if you are prone to dry skin. Moisturizers lock in moisture in the skin and can be particularly helpful when applied after showering. A thick emollient moisturizer will be best for dealing with severely dry or cracked skin.

Applying petroleum jelly

Petroleum jelly is a simple topical remedy that can help protect the skin while healing cracks. Petroleum jelly can be beneficial when dealing with cracking skin or dry lips.

Gentle Exfoliation

Sometimes, exfoliation can be a great way to remove dead cells from the skin’s surface and reduce dryness and cracking, particularly on the hands and feet. After soaking feet in water for about 20 minutes, exfoliation can be done with a pumice stone. Apply a moisturizer after using the pumice stone.

When Should I See a Dermatologist?

If you’ve tried just about everything to get your dry skin under control on your own and you still aren’t seeing results after two weeks, it’s time to turn to your dermatologist. You should also call your dermatologist if your symptoms get worse or if your skin shows signs of infection, such as,

  • Bleeding
  • Pus
  • Severe or increased redness
  • Fever

If dry, cracked skin has become the norm, and no moisturizer seems to be helping, it’s probably a good idea to turn to your dermatologist for answers.

Learn more about psoriasis, its warning signs and how to treat it.

Psoriasis is a chronic inflammatory skin disease that can impact a person’s appearance, health and quality of life. You should turn to a dermatologist if you suspect that you might be dealing with psoriasis. While there is no cure for this disease, there are ways for a dermatologist to help you better manage your symptoms and provide you with relief.

What is psoriasis?

According to the National Psoriasis Foundation, more than 7.5 million adults in the US are living with psoriasis. This immune disorder causes widespread inflammation, particularly of the skin, which results in the development of raised, scaly red plaques on the skin. These plaques may also sting or burn and typically appear on the knees, elbows and scalp.

In some cases, some people with psoriasis may also develop joint stiffness, swelling and pain. This condition is known as psoriatic arthritis, and it’s essential that you turn to a doctor right away if you notice symptoms of arthritis and psoriasis.

What can cause psoriasis to flare up?

Psoriasis comes and goes, so it’s essential to recognize what triggers your flare-ups to avoid them as much as possible. Common triggers include,

  • Stress
  • Other infections, including skin infections
  • Cold, dry weather
  • Sunburn
  • Injuries to the skin such as a bug bite
  • Alcohol consumption
  • Steroid use
  • Certain drugs, such as high blood pressure medication
  • Smoking or being around smoke

When should I see a dermatologist?

If you notice red, cracked or dry patches of skin on your body, it’s a good idea to have your dermatologist look to determine whether or not you could have psoriasis. Suppose you have already been diagnosed with psoriasis. You may wish to turn to a dermatologist regularly if your current treatment plan isn’t working or noticing new or worsening flare-ups.

How is psoriasis treated?

The fast turnover of skin cells leads to the formation of these plaques. To prevent this rapid turnover, there are a variety of lifestyle, topical treatments and therapies that a dermatologist can provide you. Common treatment options for psoriasis include,

  • Topical steroids
  • Retinoids
  • Salicylic acid
  • Phototherapy
  • Biologics (for severe and treatment-resistant forms of psoriasis)

Suppose you live with psoriasis or think you might be dealing with psoriasis. In that case, it’s important that you turn to a dermatologist who can provide you with a proper diagnosis and customized treatment plan.

Wondering when a rash is a cause for concern?

We’re all going to deal with a rash at some point, and while the good news is that many of them can be treated from the comfort of your own home, sometimes you will need to turn to a dermatologist for medication. Here are the causes of a rash,

Fungal Infection

One of the most common fungal infections that result in a rash is ringworm. Fungal infections can also affect the nails and hair. Yeast infections caused by the candida fungus can also result in rashes of the mouth, groin, or vagina. Less common fungal infections may result in those with compromised immune systems (e.g., patients who have HIV).

Minor fungal infections may be treated with over-the-counter anti-fungal creams or ointments. A dermatologist should treat more severe or persistent fungal infections.

Viral Infection

The most common virus to produce a rash is the herpes simplex virus, both type 1 and type 2. Type 1 usually causes cold sores of the lips and nose, while type 2 leads to sores on the genitals. Those with an HSV flare-up may develop a tender rash on the palms. Chickenpox and shingles (caused by the herpes zoster virus) also result in itching, burning, and painful rashes.

Epstein-Barr virus, best known as mononucleosis or “mono,” can also lead to a mild rash that appears within a few days of being infected. If you develop a rash, a sore throat, swollen lymph nodes, and a fever, you should see a doctor.

Bacterial Infection

Staphylococcus (e.g., folliculitis; cellulitis; impetigo) and streptococcus (e.g., strep throat; scarlet fever) are two common bacterial infections that lead to a rash. Sometimes Lyme disease is characterized by a bull’s eye-like rash surrounding the tick bite.

Parasitic Infections

Parasites that cause a rash include lice and scabies, which can be passed from person to person. Lice most commonly affect the scalp, while scabies can cause an itchy, pimple-like rash that usually appears on the armpits, wrists, elbows, beltline, and buttocks.

Other Causes

Noninfectious rashes are also caused by drugs, eczema (e.g., atopic dermatitis), allergic dermatitis, autoimmune disorders (e.g., lupus), and food allergies.

It isn’t easy to tell what’s causing your rash, but if you are dealing with new, worsening, or severe symptoms or the rash is spreading, it’s always good to turn to your dermatologist for treatment.

Tags: Mole   Irregular Mole  
Irregular MoleEducating the public on skin cancer is incredibly important. After all, you’re the one that looks at your skin every day, so you should know how to spot early warning signs of skin cancer. While there are certain risk factors that can increase your risk for melanoma and non-melanoma skin cancers, it’s important for everyone to visit a dermatologist once a year for a comprehensive skin cancer screening. In the meantime, here’s what to look out for.

What is an irregular or atypical mole?

Medically referred to as dysplastic nevi, these irregular moles are benign but having them could put you at an increased risk for developing melanoma over your lifetime. These moles can develop anywhere on the body but are most often found on sun-exposed areas of the skin. Since these moles vary greatly in appearance it’s important to monitor your moles regularly so you can recognize when unusual changes are occurring and call your dermatologist.

What does an irregular mole look like?

The American Academy of Dermatology (AAD) offers a simple ABCDE guideline to follow to be able to spot unusual or suspicious changes in a mole. Here’s what the ABCDEs stand for:

Asymmetry: when the halves of the moles don’t match each other in shape or appearance this could be a sign of a cancerous mole
Border: a jagged, irregular, or scalloped border can be a sign of melanoma
Color: if a mole has multiple colors or changes color this is also a warning sign not to ignore
Diameter: melanoma is often larger than 6mm (the size of a pencil eraser), even though they can be smaller
Evolving: healthy moles stay relatively the same over the years so if your mole bleeds, crusts over, itches, or changes appearance you should schedule an appointment with your dermatologist

When should I see a dermatologist?

If you have any concerns about a mole don’t hesitate to call your dermatologist to have it checked out. The sooner melanoma and non-melanoma skin cancers are detected and removed the better. Of course, everyone can benefit from visiting a dermatologist at least once a year for a comprehensive skin cancer screening. You should also be performing self-exams once a month to keep track of your moles.

If you have an irregular mole or a mole that’s changing in appearance, it’s best to play it safe and schedule an evaluation with a dermatologist who can examine the mole to make sure it hasn’t turned cancerous.

Tags: Spider Veins  
Spider VeinsMost of us, at some point during our lifetime, will develop spider veins—those tiny, purple, web-like veins caused by twisted blood vessels. While they aren’t serious they can be uncomfortable and unsightly. If you’ve been wondering about ways to get rid of spider veins, a dermatologist is going to be the ideal medical specialist to turn to, to discuss treatment options.

What are spider veins?

These small raised, swollen, and twisted blood vessels are often red, purple, or blue and are easily seen through the skin. Spider veins most commonly appear on the legs and face.

Are there any symptoms of spider veins?

Both spider and varicose veins often don’t produce any symptoms; however, some people may experience swelling, aching, burning, tingling, or cramping of the legs.

What causes spider veins?

There are a variety of reasons why spider veins may develop including,
  • Obesity
  • Heredity
  • Jobs that require standing for long periods (e.g. nursing)
  • Birth control pills
  • Medical history of blood clots
  • Pregnancy
Are there risk factors for developing spider veins?

Besides the causes above, age and gender also play a role. More women than men develop spider veins. The likelihood of developing spider veins as you age also increases. It’s believed that anywhere from 30 percent to 60 percent of adults have spider veins.

What can I do to treat spider veins?

There are many different ways in which a dermatologist can treat spider veins including,
  • Recommending support stockings: They can reduce any pain or discomfort associated with spider veins
  • Altering your lifestyle: this includes losing weight if necessary, taking care of your skin, and increasing physical activity (which can sometimes help spider veins)
  • Sclerotherapy: a common procedure used to remove unsightly spider veins. By injecting saline solution into the vein, the vein will disappear over the next couple of weeks
There are other solutions out there as well including surgery, intense pulsed light (IPL) treatment, radiofrequency occlusion, and endovenous laser treatment. We would be happy to sit down and talk with you about which treatment would work best for your needs.

Dealing with spider veins? Want to get spider vein-free legs that you can wait to show off? If so, it’s the perfect time to turn to your dermatologist to discuss ways of getting rid of your spider veins.
