Hot Tub Blues

October 26th, 2016 | General Info

untitled-design-32Hot Tub Itch

There is nothing quite like slipping into a hot tub after a day of battling the winter elements. The positive memories of the experience can quickly fade if the event is followed by hot tub itch, medically known as pseudomonas folliculitis.  If an itchy rash consisting of elevated bumps, some pus filled, appears within 12 to 48 hours after a hot tub immersion then it is likely hot tub folliculitis. These bumps may develop into dark red, tender papules.

What causes hot tub itch?

A hot tub rash occurs when a bacteria known as Pseudomonas enters the pores of the skin causing an infection. Pseudomonas lives naturally and without consequence in the skin of about 15% of the population.

If Pseudomonas is introduced into improperly treated and maintained hot tub water the bacteria will take up residence in it. Once this happens it is very difficult to ‘evict’ because the bacteria develops a slimy layer that protects it from recommended levels of hot tub disinfectants. Super chlorination may help to get rid of the problem but it might be necessary to drain and scrub the tub with bleach in order to ward off the infestation.

The second way that pseudomonas may infect hot tub enthusiasts is at a ‘hot tub party.’ Large numbers of people in a hot tub may cause a temporary drop in the disinfectant levels in the tub. This allows the pseudomonas from a carrier (the 15% of the population who carry pseudomonas naturally) to travel to other participants at the party. The hot water causes skin pores to open and the bacteria finds new hosts in the follicles of fellow partiers. Once the party is over and the tub is vacated the disinfectant levels increase and the remaining bacteria is killed before it has time to become established in the water. The party goers however go home with an unexpected and often unwelcome companion in the form of hot tub itch.

What can be done to treat hot tub itch?

Hot tub folliculitis given time will resolve spontaneously however most people do not like the appearance and the itch can drive them crazy. An antibiotic (Cipro) will rid the body of the bacteria and a medicated cream containing 2% hydrocortisone is helpful in managing the itch.

Eye Creams – Do They Work?

Eye Creams – Do They Work?

 Knowledge is power – how is the skin around your eyes different from the rest of the skin on your face?

The skin around the eyes does not differ from the skin on your face. This is a misnomer propagated by the cosmetic industry.  Aging of the skin around the eyes is caused by heredity, sun damage, muscle pull, fat loss and gravitational pull on the skin. Often wrinkles appear first around the eyes because of the dynamic movement of the muscles around the eyes and the breakdown of the building blocks of the skin due to sun damage.  Sun damage leads to wrinkles, pigment changes and vascular discoloration which contribute to the appearance of aging. It also leads to skin cancers which if left unchecked can damage the eye itself. Another little known fact about aging around the eyes is that the eyelashes become shorter and thinner.

Are you wasting your money or do over the counter eye care products work?

The skin around the eyes is just as susceptible to sun damage as the rest of the face therefore protecting the skin around the eyes from the sun’s rays is important. The single most important over the counter product for skin around the eyes as well as the rest of the face and neck is sunscreen.

Sun glasses designed to protect against the ultraviolet rays of the sun will not only protect the delicate skin around the eyes but will also protect the eye itself from UV light which may cause cancer of the retina. A broad-brimmed hat or visor is also beneficial.

Over the counter eye care products may cause some superficial irritation which results in some slight swelling or edema around the eyes which in turn may make wrinkles less obvious. This effect is temporary and does not actually facilitate any repair. Some topical agents, such as tretinoin and glycolic acids have proven to stimulate collagen repair in the skin and to reverse some of the signs of aging. The concentration required to promote a change is generally not found in over the counter products and must be obtained from pharmacist with a prescription from a physician.

 Treatment options for reversing signs of aging around the skin include:

  • Sunscreens with an SPF of 45 or more plus protective eyewear and hats to prevent photo aging.
  • Medicated creams for superficial improvement of fine wrinkles, texture and colour around the eyes.
  • Botox Cosmetic to treat dynamic wrinkles.
  • Fractionated laser resurfacing to erase fine wrinkles and address texture changes.
  • Blepharoplasties of the upper and/or lower eyelids to reduce redundancy.
  • Latisse to promote the growth of longer and thicker eyelashes.

Golf, Ticks and Lyme Disease

June 8th, 2016 | General Info

tickThe beauty of many of our Alberta golf courses is the tree lined fairways. I can attest to the fact that I have had up close and personal encounters with some of these trees while tromping through the underbrush in an attempt to find my ball. Having read an article written by Michelle Gagnon in the Rocky Mountain Outlook about Ticks and the risk of the Lyme disease I am more inclined to take the penalty strokes and leave the ball where it lies.


Lyme disease is caused by a bacterium called Borrelia burgdorferi. The bacterium is spread from small animals to humans by little biting arachnids called ticks. Ticks are like vampires – they attach to you and suck away, quite possibly and inadvertently leaving behind the bacterium called Borrelia burgdorferi. The name of the bacterium is not as important as the damage it can do if a person is unfortunate enough to be exposed to it.

One of the first signs of Lyme disease is a bulls-eye rash around the site of the tick bite. Not all people get this rash so early detection may be missed. Other symptoms in the early stages are: fatigue; chills; headaches; joint and muscle pain and/or swollen lymph nodes. If you experience these flu- like symptoms after you have been in or near tree and shrub bed areas it may be prudent to visit your family doctor.

tick bite

If untreated the consequences may become more severe – possibly involving the central and peripheral nervous systems; the joints; and the heart. Afflicted individuals often experience extreme fatigue and general weakness.

Specialized tests are necessary to confirm the diagnosis of Lyme disease. Treatment depends on the symptoms and where in the body the bacterium has settled.

As with many medical conditions awareness and prevention is the best approach. After you, your family members and your pets have been romping in the woods do a self check to insure that one of these little critters has not attached itself to your skin. If a tick has decided to tag along for the ride home remove it with caution. Using tweezers grasp the tick’s head and mouth parts as close to the skin as possible and pull gently. Do not traumatize the tick by squeezing or twisting it – this can cause the tick to regurgitate its stomach contents into your blood. Yuck!  As much as you may wish to destroy it – resist the urge. Place it in a zip lock bag as it may provide important information if you develop symptoms.

New Cleansing Routine May Cause A Rash

December 10th, 2012 | General Info

I recently heard a young woman enthusiastically describe a new cleansing routine involving the application of cooking oil followed by hot water to clean her skin. She informed me that her skin was softer and pimple free because of this new ‘natural’ regimen.

In an effort to forestall a possible skin disaster I explained that it is quite likely that this new routine might result in a condition call ‘cosmetically induced seborrhea.’ The purpose of cleansing the skin is to remove cosmetics, dirt and grime, and dead skin cells. The oil routine might successfully remove make up, however is unlikely to get at all the dirt and grime and will probably not remove the dead skin cells. If these cells are not removed they become matted to the skin. The build up causes flakiness and inflamed oil glands leaving a scaly, red rash that is sometimes itchy (seborrhea). People often interpret the flakiness as dry skin and apply more occlusive moisturizing creams or lotions to the skin. A vicious cycle begins which often results in a visit to the dermatologist.

The best cleansing routine is:

  • Remove make up with a makeup remover.
  • Wash the skin with warm water and a cleanser – mild soaps are better than cream cleansers. Glycerine soaps such as Pears and Neutrogena or Cetaphil Lotion are recommended.
  • Wait 30 minutes after cleansing to give your skin time to replenish its natural oils. If your skin is tight and dry then a light moisturizer may be necessary. Use a moisturizer with sunscreen protection.

How to be Safe In the Sun

July 24th, 2012 | General Info, Treatments

Healthy skin, like a healthy body begins with prevention. Exposure to the sun not only ages the skin but it also causes skin cancer.

The sun emits three forms of radiation: infrared, visible and ultraviolet. Infrared and visible light are valuable because they provide warmth and the ability to see. But ultraviolet light can be harmful. It consists of three basic wavelengths: Ultraviolet A, Ultraviolet B and Ultraviolet C. Each penetrates the atmosphere and affects our health in different ways.

So the first step towards protecting our skin would be to protect the Ozone layer. Work with the scientists around the world to do your part to keep and maintain clean air.

The next steps require daily vigilance:

  • Apply a broad spectrum sunscreen with an SPF of 50 to sun exposed areas of the skin. This will protect you through a normal day of getting in and out of the car, going to the office etc.
  • If you plan to be in the sun all day then use an SPF of 60 or more.
  • Wear waterproof or water-resistant sunscreens if you plan to be in the water. Reapply often.
  • Wear sunscreen under loosely woven clothing as the sun will penetrate the cloth. The sun also penetrates wet clothing.
  • Reapply sunscreen throughout the day according to the amount of sun exposure you receive. If you are participating in sports which make your perspire, reapply sunscreens every hour.
  • Be thorough in your application; sun exposed skin which in not covered will burn. Remember the back of your ears and the tops of your feet and toes!

Wear protective clothing when exposed to the sun for long periods of time: hats, gloves, long sleeves, UV protective sun glasses.

Seek shade.

Avoid tanning beds. Fifteen minutes of exposure to UVA in a tanning bed is equivalent to three days of sitting in the sun!

A tan signifies that the sun has damaged the skin to some degree. The belief that a preliminary tan before a holiday will protect you from the harmful rays of the sun has little substance. The protection offered by a preliminary tan would only be equivalent to an SPF of 2.

Use sunscreen regularly and protect the health of your skin.

What you need to know about cosmetics.

July 18th, 2012 | General Info

Makeup is the palette of the cosmetic artist. Features of beauty can be accentuated and less desirable features can be subdued. Artful application of makeup can greatly enhance ones natural beauty, yet when poorly applied makeup can be distracting.

Cosmetics are a multi-billion dollar industry. As the ‘baby boom’ generation ages, the industry has shifted its emphasis away from products for the younger generation to ‘anti-aging’ products. Magazines are full of advertisements for products suggesting that they alone have the answer to aging. They would have your believe that the daily use of their product will assure you an everlastingly youthful appearance. Their claims, though seductive are questionable.

Let’s review the components of the skin. The skin has three layers: the epidermis (top layer), the dermis (middle layer) and the layer of cushioning fat (bottom layer). Aging largely affects the dermis and at this level a product must reverse the signs of aging to be as effective as it claims. At this time most products are incapable of penetrating the epidermis and are therefore rendered relatively impotent in their impact on aging.

However, liposomes have appeared on the scene. These micro-balloons can carry active ingredients to deeper levels of the skin’s surface and beyond. For the quick delivery of medications they are very effective. However as cosmetic companies begin to use these microscopic vehicles to transport the active ingredients in their products, which they claim will prevent or reduce the signs of aging, the risk to the user increases.

This has caught the attention of the Food and Drug Administration in the United States and the Health Protection Branch of Canada. The outcome of their scrutiny will have one or both of two possible outcomes:

First, if the product actually alters the tissue, then it is no longer considered a cosmetic product. This means that the product must undergo scientific evaluation to support the claims, a very expensive process. If the claims are substantiated, the product must be reclassified as a drug, which means it will be shelved differently in stores and the marketing strategies for the product will have to change.

Second, claims that are unsubstantiated may be considered fraudulent. The product could then be removed from the shelves without further warning and class action suits may ensue.

These consequences apply to product claims whether liposomes are used or not. Some companies have chosen the simpler route of changing the anti-aging claims on their labels and in their advertising. However the competition is stiff so many ignore the warnings and continue to press their claims.  For the most part it is up to you, the consumer, to evaluate the legitimacy of cosmetic products.
