Find out how this pigmented skin condition is treated.

Are you or someone you love dealing with vitiligo? The Mayo Clinic reports that there are more than 200,000 new cases of vitiligo each year in the US alone. Vitiligo is a chronic disease where the melanin, which gives your skin its pigment, either dies or the body stops producing it. As a result, there are white patches of skin all over the body. So, you may be wondering how this condition occurs or how you can treat it. This is when it’s important to turn to your dermatologist.

What causes vitiligo?

Unfortunately, researchers still do not know why some people develop vitiligo. It may be the result of an autoimmune disease, where the body attacks the melanocytes in the skin. Some researchers also believe that something as simple as a sunburn or even emotional stress could cause vitiligo; however, the cause is still unknown.

Who is at risk for developing vitiligo?

Even though this condition can appear at any time in a person’s life it more commonly occurs in your 20's. It affects both men and women of all races; however, vitiligo is more noticeable in those with darker skin. Those with autoimmune disorders are often more likely to develop vitiligo than those who do not have an autoimmune disorder. Genetics may also play a role; however, parents with vitiligo won’t necessarily pass this condition onto their child.

What are the symptoms of vitiligo?

Vitiligo is characterized by large white patches of skin, which may appear anywhere on the body. These patches most commonly appear on the face, hands, feet, arms, and other sun-exposed areas. Sometimes the white patches will spread over time. How quickly the patches spread will vary from person to person; however, sometimes the patches won’t spread at all.

How is vitiligo treated?

It’s important to turn to a dermatologist that you trust if you think you or a family member is dealing with vitiligo. During your consultation, your doctor will examine your skin to determine how widespread and numerous the patches are so that we have a better idea what type of treatment will be the most effective.

We will also go through your medical history and ask you questions about your condition. Treatment for vitiligo, like most skin disorders, will not work overnight. In fact, there is often a trial-and-error period to try and find the best treatment option.

The most common types of vitiligo treatment include medication, light therapies, and surgery, all of which are designed to restore pigmentation back into the skin.

Prescribed medications may be applied topically or taken orally. Certain UVA/UVB light therapy treatments may also improve your condition. Skin grafting surgery may be recommended, in which your dermatologist will remove skin from another area of the body and apply it over the patches to hide them and even out skin tone.

Your dermatologist can also recommend a full-spectrum sunscreen to protect your skin when going outside, as well as any counseling and support you may need. If you or someone you love is looking for vitiligo treatment, contact your dermatologist today.

The fountain of youth is, unfortunately, a myth. Luckily, you can tap into its mythical powers in real life with cosmetic dermatological botoxprocedures such as Botox. This procedure can help you attain a more youthful appearance in just a single visit with your dermatologist, Dr. Linda Banta at Stone Oak Dermatology in San Antonio, TX.

What is Botox?
Botox is a dermatological procedure which injects a substance directly into the muscle that lies underneath the facial skin. The substance freezes the muscles, allowing the skin on top to smooth out. The process reduces fine lines and wrinkles and gives you a more youthful appearance. Since the skin no longer moves and folds, Botox also helps to prevent new wrinkles from forming.

Are Botox Injections Safe?
Botox has been around for many years and is considered safe. It was FDA-approved in 2002 and has since helped many people reduce their fine lines and wrinkles. It produces minimal side effects; the most common are slight bruising at the injection sites and some swelling and redness.

How does Botox Work?
Your San Antonio, TX, dermatologist will ask you to lie on an examination table and cleanse your skin. Then, they mark which muscles could benefit most from Botox and begin the injections. Dr. Banta injects the Botox substance into the facial muscles by using a fine needle. Most patients report that the procedure feels like a small pinch. The procedure takes only about 15 minutes and has no downtime, meaning patients can go right back to their daily activities. Results of Botox treatment typically last three to four months.

Why Do I Have Excessive Sweating? 

Do you commonly find that your armpits or feet are drenched with sweat, despite being in mild weather and not being active? If so, you may be one of the 1-3%  of the population that has hyperhidrosis, a disorder that entails having hyperactive sweat glands. Read on to learn the signs of this condition and to find out how your local dermatologist can help you cope with the often-uncomfortable symptoms that define it!

The Two Types of Hyperhidrosis

Before going further into the discussion of hyperhidrosis symptoms, it is important to establish that there are two types of the condition:

  1. Primary Hyperhidrosis: People afflicted this disorder type possess a certain type of gland, termed, “eccrine sweat glands.” These sweat glands will cover the entire body, although they will be especially prevalent on the feet, armpits, face, and palms.

  2. Secondary Hyperhidrosis: While also causing excessive perspiration on the body, this kind of hyperhidrosis is in fact a side effect of another medical condition or medication (hence the “secondary” designation). Conditions that generally cause secondary hyperhidrosis include, fever, anxiety disorder, menopause, and obesity among others.

Possible Treatment Options For Hyperhidrosis

We know how uncomfortable excessive sweating can be, and luckily, there are a number of different treatment options available to those who struggle with hyperhidrosis. Of course, given that each case differs largely from the next, you will need to meet with your local dermatologist to find out which treatment course is best for you!

Some possible treatment options include:

  • Aluminum chloride containing prescription antiperspirant
  • Glycopyrrolate containing prescription creams.
  • Nerve-blocking medications
  • Botulinum injections
  • Antidepressants or anxiety relieving medication (in the case of secondary hyperhidrosis)
  • A number of surgical options (reserved for very serious cases)

Acne. It bothered you as a teen, and as an adult, you're experiencing those pimples again on your back, face and chest. Act on the acnebreakout soon, says the American Academy of Dermatology, or your acne could worsen. Why not visit your dermatologist in San Antonio, TX Dr. Linda Banta? At Stone Oak Dermatology, she sees patients of all ages and skin types, helping them control their acne.

What is acne?

It's an unsightly and embarrassing skin condition affecting literally millions of Americans. The blackheads, whiteheads, papules and cysts characteristic of acne develop in the oily sebaceous glands of the skin. When these become plugged with sebum or oil, and dead skin cells, acne breaks out. Besides how bad it looks, acne can become infected and even leave scars.

How can acne be treated?

As with any medical condition, prevention helps. So, if you're prone to acne, be sure to:

  • Wash your face and other affected areas with an over the counter acne scrub twice a day.
  • Be gentle as you wash, using your fingertips to gently exfoliate. Never scrub hard as this only further irritates the skin.
  • Avoid picking and squeezing lesions as this worsens how they look and feel and also can cause infection.
  • See your dermatologist in San Antonio right away when your at-home regimen is ineffective.

At Stone Oak Dermatology, Dr. Banta will examine your skin closely to determine what course of in-office and prescription treatments may help you best. Common options include:

  • Benzoyl peroxide available in various concentrations and ways of application (face clothes, creams, scrubs)
  • Tretinoin, a cream, gel or topical solution which limits the growth of skin cells affected by acne symptoms
  • Surgical extraction in the office (for deep cysts)
  • Topical antibiotic cream and oral antibiotics

Get clear and stay clear

Call Stone Oak Dermatology for a consultation with Dr. Linda Banta. Love your skin again. Phone us at (210) 494-0504.

Tags: Cold sores  

Cold Sores can appear on the outside of the lipWhat are cold sores and what can you do to relieve your symptoms?

Most people who have had cold sores often know when they are about to appear. The tingling and burning sensation around the mouth is often the first indicator that a cold sore is imminent. Approximately 80 to 90 percent of Americans have been exposed to the herpes simplex virus type 1 (HSV­1), which causes cold sores. If you have cold sores then you are probably wondering more about this condition, how to treat it and what it means for your health.

What are the symptoms of cold sores?

Symptoms often stick around for about two to three weeks. Besides experiencing oral sores around the mouth, people may also experience flu­like symptoms such as fever, muscle aches and fatigue. These oral sores will often appear as tiny blisters that break open and scab over.

When should I see a doctor about cold sores?

While cold sores often don’t warrant a trip to the dermatologist, there are certain times when it might be advisable. These sores can be painful, so if you find it difficult to eat or talk then you will want to talk to your doctor about the best ways to alleviate the pain to make eating easier. The last thing you want to deal with is dehydration on top of an outbreak.

If these oral sores look different from other cold sore outbreaks, then it’s also worth seeing your dermatologist to receive a proper diagnosis. Those with weakened immune systems due to chronic illness or chemotherapy should also see their dermatologist to prevent further complications.

What treatments are available for cold sores?

While many cold sores will go away without the need for treatment, if you are experiencing pain we may prescribe a topical anesthetic to reduce your discomfort. There are also over­the-counter treatments that speed up healing and reduce pain. However, for those with severe infections your dermatologist may also prescribe an oral antiviral medication.

Those with weak immune systems and those who become dehydrated as a result of cold sores may need to go to the hospital to prevent further problems and to receive oral antivirals.

While you cannot cure the virus that causes cold sores, there are certainly ways to reduce your symptoms. Talk to your dermatologist to find out more!
