Too much sweat?

Question:  Is there such a thing as sweating too much? What can I do about it if I’m constantly soaking through my clothes? It’s so embarrassing, especially at work!

shutterstock_155697284Answer:   Yes, the condition definitely heats up during the summer months but can plague sufferers all year long with overly sweaty armpits, palms and even on soles of the feet. It  is called hyperhidrosis which just means “excessive sweating.”

Hyperhidrosis is simply abnormally heavy perspiration. Sweating is a normal bodily function, but some people may have overactive sweat glands that produce more sweat beyond what is required for regulation of body temperature. It can be most noticeable at the armpits because sweat can soak through clothing and become obviously embarrassing. Or you may also be aware your palms are often sweaty so you avoid shaking hands with others.  Hyperhidrosis can occur  in many parts of the body whether exposed to triggers such as heat, physical activity or exertion, embarrassment, stress or not.

How do we treat excessive sweating?

First, we’ll evaluate your excessive sweating for any potential causes of secondary hyperhidrosis (for example, an underlying disease that causes excessive sweating such as hyperthyroidism).

To gauge your sweating problem, we will try you on stronger prescription-grade antiperspirants which can also help block sweat glands to reduce sweating. Typical over-the-counter antiperspirants are 1-2% aluminum chloride but prescription products can contain up to a 20% solution of aluminum chloride hexahydrate or similar aluminum salts. While these can be irritating in those with sensitive skin and sweat glands, they do reduce perspiration, however they require continuous usage.

After a few weeks of trial, if the prescription products do not reduce your sweating problem well enough, we can now use Botox® (onabotulinumtoxinA), which is FDA approved for the treatment of excessive sweating of armpits. We also use Myobloc® (rimabotulinumtoxinB) or Dysport® (abobotulinumtoxinA) off-label as an alternative, especially for those who have excessive sweating on palms and soles of feet.

These injections work to temporarily de-nerve the sweat gland and results in a local reduction in sweating where injections have been administered for up 5 months. Injections must be repeated at regular intervals to keep excessive sweating at bay and you may still need to use an antiperspirant.

What to do about an inflamed, raised, hard scar

Question: I had an injury to my shoulder earlier this year and while the wound has mostly healed and is no longer scabby, the resulting scar is still painful, raised, hard and lumpy. It’s bigger and uglier than the original wound. What can I do?

Answer: There are two types of scars that resemble what you describe and there’s a lot we can do in the dermatologists office to help them look and feel better.

Keloid scar

Keloid scar

Keloids and Hypertrophic Scars

This type of scarring is usually after local skin trauma (e.g., laceration, tattoo, burn, vaccination or surgery) or as a result of an inflammatory skin disorder (e.g., acne, bites or abscesses).

Scars are composed of new connective tissue that replaces lost tissue in the dermis or deeper parts of the skin, as a result of injury. Their size and shape are determined by the form of the previous wound. The process of scarring is characteristic of certain inflammatory processes. A resulting scar can be thin (atrophic) or thickened, fibrous and overgrown. Some individuals and some areas of the body (e.g., anterior chest) are especially prone to scarring. Scars may be smooth or rough, pliable or firm, they can be pink or violaceous or become white. They can also be hyperpigmented (darkened). Scars are persistent and normally become less noticeable in the course of time.

At times though, and in certain anatomical locations (e.g., shoulders, sternum, mandible and arms) they can grow thick, tough and corded forming a hypertrophic scar or keloid. Under normal circumstances,  wound healing takes place through the rapid and repeated reproduction of fibroblasts (the most common cells of connective tissue) at the wound site. But when fibroblast activity continues unchecked and excessive collagen (protein found in connective tissue) is deposited at the site of injury, the scar gets too big and a hypertrophic scar or keloid is formed.

Hypertrophic Scar remains confined to the borders of the original wound and most of the time, retains its shape. It is characterized by hardness, redness and irritation compared to the surrounding skin and can take the form of a firm papule or nodule.

Conversely, a Keloid is an overgrowth of dense fibrous tissue that you’ll notice extending beyond the borders of the original wound. Like a hypertrophic scar, a keloid can be hardened, raised and often darkly discolored. Keloids do not regress, appear to get better or shrink over time on their own. Instead they grow in a pseudo tumor fashion and distort the size and shape of the original lesion.

If you know you have a hereditary predisposition toward keloid scarring, mention that to your dermatologist because then we will not try to surgically remove them (called excision) because keloids tend to recur.

The differences… A hypertrophic scar can occur at an any age and usually stays within the borders of the original wound, whereas a keloid commonly occurs in the third decade and enlarges beyond the area of the initial wounding with web-like extensions. Keloidal growth can also be triggered by pregnancy and compared with hypertrophic scars, a keloid can often be painful and super-sensitive.

How we treat stubborn keloids and hypertrophic scarring

We often use a 3-step process in the office to attack raised, hardened scars as soon as we notice a scar is exhibiting signs of hardening, as early as one month-post op, in the case of a scar due to surgery.  The earlier you treat a keloid or hypertrophic scar, the better your results will be.

We inject  5-fluorouracil “5-FU” (used primarily as an anti-cancer drug but also used for the prevention of scars in glaucoma surgery for at least 15 years) combined with a specific low-dose corticosteroid (to reduce further inflammation and any pain) along with Pulsed Dye Laser treatments.

5-FU works to reduce skin’s metabolism rate and inhibits the over-production of the fibroblasts building up on and around the wound. We combine that with Kenalog (triamcinolone), the low-dose corticosteroid, and perform injections one to three times per week, at regular intervals such as Monday, Wednesday and Friday, depending on how red, hardened and inflamed the scar is.  Once the scar softens, injections can be reduced to two times per week, once a week and then every other week, monthly and finally, every six months. The Pulsed Dye Laser is used to decrease any redness, to normalize the wound surface and improve skin texture at the scar and to further blend scar into surrounding skin and we perform those treatments in intervals of four to eight months apart.

While any keloid or hypertrophic scar can be treated with this technique,  you’ll get the best results the younger the scar is. The more inflamed and symptomatic the scar, the better the response to treatment. Older scars that have been hardened for many years and are not inflamed, red, itchy or painful, will not respond as quickly or as thoroughly. Hypertrophic scars respond better than keloids, which frequently recur, although small isolated keloids (less than 2 cm in diameter) usually completely resolve with this technique without recurrence.

No matter what, keep all scars out of the sun for best healing, at least until the “pink” of new skin is gone because exposure to the sun only makes scars darker.

What good is coconut oil for hair and skin?

Question: I’ve been reading more and more about using coconut oil for hair and skin. Do you think this is a good idea? Can you tell me how to buy coconut oil and how to use it properly?

As a solid its an ointment or balm, warmed to a liquid a liquid its a moisturizing, conditioning oil

As a solid, its an ointment or balm, warmed to a liquid, its a moisturizing, conditioning oil

Answer: I love coconut oil as an added treat for hair and skin (as long as you are not allergic to nuts or coconut). But, I only recommend buying organic unrefined expeller-pressed virgin coconut oil (also called VCO).

I think VCO is a great addition to any hair and skin routine because:

  • It has no preservatives, additives, or color.
  • It’s available at any local health food store or online.
  • It’s affordable at $9 for a small 14 oz. jar.
  • It’s a multi-use beauty product:  Coconut oil is  a solid (like butter) at room temperature and ideal as an ointment or lip balm, but if you place the jar in  warm water, it melts into a liquid oil perfect for massaging, baths, a moisturizer or a hair mask.
  • That smell is like being on a desert island (refined VCO  does not retain its natural coconut aroma).

The real beauty of VCO for skin and hair is its natural, molecular composition

Not only does VCO have a high saturated fat content-composed of 90% saturated triglycerides, but its low molecular weight and straight linear chain (called a medium-chain fatty acid, in contrast to other saturated fats comprised of long chain fatty acids which make them larger molecules), it is able to permeate the hair shaft  and skin surface rather than just sitting on top. That’s what makes it so effective. If you use it at room temperature (when it is solid) it is the perfect ointment to relieve dehydrated, chapped, scaly and itchy skin and it can even improve symptoms of psoriasis and excema.

The medical literature supports my own observations of VCO as a healthful skin conditioner and moisturizer. Studies have shown that  VCO use may improve skin barrier function (protecting skin from bacteria and fungal intrusion) and  decrease trans-epidermal water loss (skin’s ability to retain moisture). Animal studies have shown that coconut oil use can improve wound healing and increase collagen production, too.

For hair, in addition to its high absorbability, VCO contains a high percentage of the saturated fat, lauric acid, which also is highly attracted to the protein in hair. Because VCO actually absorbs through the hair shaft, it has positive effects on the strength of hair while it prevents hair damage and protein loss from styling, brushing and even chemical treatments.

 A little coconut oil on your skin and hair goes a long way:

  • As a daily body moisturizer, after shower or bath
  • As a bath oil
  • As a skin exfoliator for skin and to help control dandruff in hair
  • As a cuticle conditioner
  • As a lip balm
  • As an intensive hair mask, from scalp to ends
  • As a scalp or body massage oil

Coconut oil can be greasy if applied too heavily, but don’t worry, it absorbs in a few minutes leaving behind that beachy smell and softer, healthier, smoother skin.

It can be applied on wet or dry skin. But only apply to dry hair because water limits the VCO from coating the hair properly and permeating the hair shaft. To remove VCO from hair, do not wet first. Simply lather up shampoo in your hands and apply directly and completely over hair and scalp, from roots to ends, then rinse thoroughly.

VCO can be applied in the same way to children and adults. Just be sure that you don’t use coconut oil at all if you are allergic to nuts or to coconut.

Have you tried virgin coconut oil yet? What’s your favorite way to use it?

Want to be 25% less likely to get age spots?

Well, I’ve been saying this to my patients for years:  Daily sunscreen use prevents the ugly results of photo-aging (spots, roughness and wrinkles caused by years of cumulative sun exposure which speeds up your skin’s natural aging process)  and finally a study published in a June issue of the Annals of Internal Medicine entitled, “Sunscreen and Prevention of Skin Aging,” has proven this to be true.

shutterstock_124869277Studies have already proven that sunscreen prevents skin cancer, but previous studies on photo-aging had always been done on mice so this new study performed on over 900 white people in Australia under the age of 55 and measured over 4 years just confirms what we dermatologists have been saying to our patients:

“If you want to keep spots and wrinkles at bay,  use sunscreen every day.”

Initially, the researchers weren’t sure exactly what effect regular comprehensive use of sunscreen would have on skin aging caused by the sun over the years and they were also curious about the effect of taking dietary antioxidants such as β-carotene supplements to delay skin aging so they tested both.

The study was broken randomly into 4 sunscreen use groups:

  1. Specific daily use of broad-spectrum (protects against both UVA & UVB rays) sunscreen of SPF 15 applied to head, neck, arms, and hands each morning and after bathing, after spending more than a few hours in the sun, or after sweating heavily and 30 mg of β-carotene.
  2. Specific daily use (as described above) of the broad-spectrum SPF 15 sunscreen and placebo.
  3. Use of broad-spectrum SPF 15 sunscreen at the discretion of the participant and 30 mg of β-carotene.
  4. Use broad-spectrum SPF 15 sunscreen at the discretion of the participant and placebo.

Photos were taken of the backs of participants’ hands at the beginning of the study and 4.5 years later and were examined for microscopic changes of skin aging by researchers without the knowledge of  which study groups the participants had been assigned.

The sunscreen use findings:

Interestingly, not all of those in the daily use group applied their sunscreen daily as directed. But more participants assigned to the daily sunscreen use group reported applying sunscreen at least 3 to 4 days each week compared to the participants in the discretionary-use group. Those in the daily-use group were 24% less likely to have increased skin aging after 4.5 years than were those in the discretionary-use group.

No overall effect of taking β-carotene supplements on skin aging was found.

My advice:  If you want to prevent discolorations, spots and wrinkles from forming due to cumulative exposure to the sun’s rays as you age, use a broad-spectrum sunscreen (and make sure it specifies so on the label) daily of at least SPF 15 whenever you are outside and exposed to the sun.  Also,  seek the shade whenever possible and wear a broad-brimmed floppy hat and sun glasses to protect facial skin and your eyes!

Allergic to sunscreen? Read labels!

Question:  My daughter is apparently allergic to many of the sunscreens I have tried on her and gets an itchy, burning rash. What is it in the sunscreens that is causing this reaction?

Answer: There could be many different chemicals causing a skin reaction.

Read those sunscreen labels!

Read those sunscreen labels!

Most commonly, allergic reactions to sunscreens are caused by one of the original UVB sunscreen protection ingredients called para-aminobenzoid acid  or PABA.

Read sunscreen labels and look for refined and newer ingredients called PABA esters (such as glycerol PABA, padimate A and padimate O) instead of the original staining, reaction-forming PABA.

 

New “broad spectrum” sunscreen ingredients

This year,  the FDA requires sunscreens to protect against both UVB and UVA rays (labeled “broad-spectrum”), so new sunscreen ingredients have been developed and included such as include Mexoryl SX (ecamsule) and  Parsol 1789 (avobenzone) which protect against UVA rays.

Physical sunscreens including  titanium dioxide and zinc oxide have been around for decades. Remember Zinc Oxide on the noses of lifeguards back in the day? These ingredients physically block and scatter UV rays. These singular sunscreen formulas have no other chemical ingredients and so may be a better choice for sensitive skins. They also go on thicker and appear “whiter,”  but they also stay on longer and are gentler to sensitive skins.

Despite advances in technology, formulating products with these ingredients without the skin-whitening effect has proven difficult.   Zinc oxide has recently been approved by the FDA, like titanium dioxide, in microsized or ultrafine grades as  an allowable active ingredient in sunscreen products with the ability to provide more full-spectrum protection. Zinc oxide is less whitening in this form than titanium dioxide and provides better UV protection. You  can now find sunscreen products that contain these ingredients in combination with other sunscreen ingredients to increase their stability in water and sun and decrease unwanted “whiteness.”

But remember sunscreen protection is all in the proper application.  And, a lot has changed in how we recommend sunscreen to be purchased and used, so it pays to stay up on the news about sunscreen so you don’t get burned (literally!)

Other buzz words for sensitive skin

You will notice  lots of colorful kids’ sunscreen products on store shelves you might want to stay away from. Try to  avoid any sunscreen products containing dyes or perfumes, which are known allergens. And, for acne-prone or oily sensitive skins, definitely check for specific products labeled, “non-comedogenic” or “won’t clog pores.”

I cannot stress enough how important it is to be aware of sunscreen ingredients, especially when allergic reactions are concerned, and take the time to stand in the store aisles and read those labels!

Little known topical ways to prevent and treat skin cancer

Question:  My dermatologist gave me a topical cream with special ingredients to prevent skin cancer where he thought it might be forming. How is that even possible?

Answer:  It is now possible and FDA-approved.  There are some new topical medications that target different mechanisms to halt cancer cells from growing.

5-fluorouracil (5-FU):  This long-standing chemotherapy drug has been used internally and is also now FDA-approved for use on top of the skin to prevent and treat superficial Basal Cell Carcinoma (BCC). It is the active ingredient in proprietary topical skin cancer prevention formularies and several prescription creams with 5-FU or related medications available by prescription.

When applied on the skin topically, 5-FU selectively targets and destroys only cancerous or precancerous skin cells damaged by sun and aging while leaving normal skin cells alone. It’s something you can use at home, under a doctor’s supervision, on many parts of the body  such as chest, neck, hands, legs and back.

A course of treatment usually lasts approximately 14 days.  After several days of initial application,  the appearance of redness, scaling, and eventually crusting occurs on treated areas and indicates that precancerous cells are dying; how soon they appear and their severity depends on the strength of the 5-FU product and how often it is applied. The end result is a healthier looking, more attractive skin with a reduced tendency to develop skin cancer.

Imiquimod:  This cream is FDA-approved to treat superficial BCC’s that works by stimulating the immune system and causing the body to produce interferon, a chemical that attacks cancerous cells. The cream is rubbed in the  the lesion 5 times a week for 6-8 weeks (sometimes longer).  This treatment can also produce some discomfort, redness, irritation and inflammation.

Cure rates for both are 80-90 percent because they kill active cancerous or precancerous cells over time instead of all-at-once.

Never self-diagnose or try to use these medications without a doctor’s supervision, as in the rare case a BCC is locally advanced or  metastasizes (spreads), the cancer can become dangerous, even life-threatening.

Have you tried 5-FU or any of the topical skin cancer prevention treatments?

 

 

 

 

 

 

 

 

 

 

See how simple a Basal Cell Carcinoma removal can be

Question: My dermatologist said my scab was a Basal Cell Carcinoma…Now what? Do I have cancer?

Answer:  Relax. A Basal Cell Carcinoma (BCC) is rarely the spreading cancer that requires the systemic chemotherapy you’re thinking of. Cure rates for BCCs are close to 100 percent, and are easily treated when caught early.

After having your skin examined, the diagnosis of BCC is confirmed by biopsy, which is when the skin is numbed with a local anesthetic and a sample of your lesion is removed and sent to be a lab for examination under a microscope. If tumor cells are present, treatment is required.  BBCs rarely spread beyond the original tumor site so we simply remove them by  any number of methods depending on the type, size, location and depth of the tumor as well as your age and general health. Since BCCs are visible on the surface of the skin, we also take the likely outcome to your appearance into consideration.

Usually, treatment is performed on an outpatient basis in a dermatology office.

A local anesthetic is almost always used so pain during the procedure is minimal, although you may have some mild discomfort afterwards.  After removing a small BCC, wounds heal and the scars are usually cosmetically acceptable (and there are many other methods or repairing  or improving any resulting damage that is undesirable to you).

The types of treatment include:

  • Curettage and electrodesiccation: The growth is scraped off with a sharp, ring-shaped instrument (called a curette), and the tumor is dried out (dessicated) and destroyed with an electrocautery needle. The procedure is often repeated during the same procedure to ensure that all the cancer cells are eradicated. It has a 95 percent success rate for smaller lesions (and often for the first biopsy), although often not useful for aggressive BCCs or in those sites that where any scarring would be highly undesirable as sometimes a white scar is left at the surgical site.
  • Mohs Micrographic Surgery:  A physician specially-trained in Mohs Micrographic Surgery removes a thin layer of tissue containing the cancer and while the patient waits, the frozen previously removed sections are examined under a microscope by the Mohs surgeon. If skin cancer is still present in any of the tissue, the procedure is repeated only on the area where those cancer cells were identified, until the last layer is cancer-free. This technique saves a great amount of healthy tissue and has a high cure rate of 99 percent or better. It is often used in cosmetically important or large, critical areas and in those areas that have recurred, are hard to pinpoint or in critical areas  with little tissue to spare such as around the eyes, nose, lips and ears.
  • Excision surgery: We use a scalpel to remove the entire growth along with a surrounding border of apparently normal skin (called a safety margin) and then the site is closed with stitches.  A specimen is sent to the laboratory for microscopic examination to verify that all cancerous cells have been removed. Although cure rates are above 95 percent, if the tissue analysis shows cancer cells at the margin of tumor, a repeat excision may be necessary.
  • Radiation: X-ray radiation may be used in tumors that are hard to manage surgically, elderly patients or other patients in poor health. The radiation is directed at the tumor, with no need for cutting or anesthesia and total destruction usually requires several treatments a week for a few weeks. Cure rates are around 90% because the technique is not precise in identifying and removing cancer remaining at the margins of the tumor
  • Cryosurgery:  While not often used, sometimes we can destroy very superficial BCCs  by applying liquid nitrogen  to the growth with a Q-tip or a spray to freeze it, which also does not require cutting or anesthesia. After the treatment, it may be blistered,  crusty and fall off within weeks and the procedure can be repeated.
  • Erivedge™ (vismodegib): The first oral medication approved by the FDA for the treatment of  advanced BCC which is used for the limited circumstance where the nature of the cancer prevents the use of other treatment options. (Should not be used in woman who are pregnant or child-bearing.)
  • Topical medications: Certain prescription topical creams, gels and solutions are FDA-approved  to treat limited specific BCCs and some are used to prevent possible BCCs from growing.

The best treatment for BCCs is prevention:  Always wear sunscreen of SPF 30 or higher on exposed skin exposed and wear a hat whenever possible!
