| Frequently Asked Questions |
| 1.What's the best general care for my skin? |
 Here are a few simple
steps that most people can take to care for and protect their skin:
In addition, proper skin care should also include seeing a dermatologist. |
| 2.
What causes acne? |
|
The truth is that we don't know the entire story, but
there are several facts that are known. Acne is caused by several contributing
factors. Hormones are a major influence on acne. That's why you don't
see acne before puberty. In women, birth control pills can either aggravate
or improve acne. This probably depends on your response to the progestins
in birth control pills. Bacteria contribute to acne - which is why either
oral or topical antibiotics help. Greasy creams, perspiration, headbands
and other things that can plug up pores make acne worse. Stress doesn't
help either. What you eat is generally not a major contributing factor
to developing acne.

3. Are tanning beds safer than the sun?
|
|
No! Tanning beds use UVA rays, and although UVA rays
are milder than UVB rays, their wavelengths are longer and they penetrate
deeper through the skin's layers. UVA rays contribute to wrinkling and
burning the skin, as well as to the development of skin cancer. So it
doesn't matter if tanning beds are advertised as a method to tan safely,
artificial UVA rays in tanning booths not only inflict the same type of
skin and eye damage as the sun, but also may be as much as 20 times stronger
than natural sunlight.

| 4. Can dermabrasion,
chemical peels, or laser treatments get rid of wrinkles; what are the
risks and benefits of each; and how long do the effects last? |
|
Yes. And though the improvements can last many years,
they are far from permanent and may have to be repeated at periodic intervals.
Dermabrasion and medium-depth chemical peels have both been used for many
years to improve the appearance of superficial wrinkling, eliminate sun-induced
pigmentation and keratoses, and to improve the overall surface texture
of the skin. In the past decade, laser resurfacing has become very popular
and for the most part has begun to replace the other two procedures because
the results are easier to control and predict. Laser resurfacing, however,
is usually more expensive. All three procedures, if done correctly, are
relatively safe, although localized scarring and pigment alterations can
occur in a small percentage of patients.

5. If I have dandruff, does that mean my scalp is dry?
|
|
No! Mistakenly attributed to dryness because of the
flaking it causes, dandruff is actually caused by excessive oil in the
scalp. Medicated shampoos can help this condition. Shampoos for oily hair
may also help to decrease oil build-up on the scalp, but these shampoos
shouldn't be used daily because they may dry out the hair (and skin) excessively.
|
| 6. Are dark-skinned
people immune to skin cancer? |
|
No! Anyone can develop skin cancer, although people
with fair complexions do tend to be more susceptible to specific types
of skin cancer and precancerous conditions than people with darker skin
tones. In addition to fair skin and light hair, risk factors for skin
cancer include exposure to toxic materials, such as arsenic and coal;
industrial x-ray exposure; scarring from diseases or burns; family history
of the disease; a tendency to freckle or burn easily; lots of sun exposure
throughout your life; sunburns as a child or adolescent.

|
7. What type of SPF should I look for in sunscreen?
|
|
Most SPFs of 15 or higher will protect against both
UVA and UVB rays. Known as broad-spectrum sunscreens, these products contain
titanium dioxide. Other active sunscreens are zinc oxide, oxybenzone,
or Parsol 1789. While sunscreen helps to minimize damaging sunburns, it
doesn't completely prevent tanning or burning and should be reapplied
every one to two hours.
|
| 8.What causes everyday
rashes, and how can they be treated? |
Everyday rashes can be caused by a number of things, from heat to insect bites to allergic reactions.They can be controlled by follwings certain steps: Shower or bathe in warm, not hot, water. Use a gentle soap-free cleanser that won't over-dry the skin, and try a bath additive.Use a moisturizer daily to help break the dry skin and itch cycle long-term. |
|
9.When should I use a sunscreen?
|
|
To help protect your skin from the damaging rays of
the sun, dermatologists recommend wearing a broad-spectrum sunscreen with
a sun protection factor (SPF) of 15 or higher every day in all seasons…in
summer and winter, on both cloudy and clear days.
A broad-spectrum sunscreen helps protect your skin from both UVA (aging) and UVB (burning) rays. UVA rays are believed to be responsible for photoaging — the damage that occurs to the skin from many years of exposure to the sun. It's important to protect your skin from incidental sun exposure like while you're driving in the car, walking outside, etc. Apply sunscreen to all exposed skin, including lips, ears, backs of hands, and neck. Apply sunscreen generously and evenly before going in the sun, and reapply frequently after swimming, exercising, or sweating. It's also important to look for a sunscreen product that is water resistant. |

10.What causes dry skin, and what can I do to improve
it?
|
|
When skin is dehydrated, the water content of the very
top layer of skin is reduced, causing it to shrink. This shrinkage creates
many of the familiar symptoms of dry skin, including itching, scaling,
loss of elasticity and tightness. Scratching further damages the skin,
leaving it vulnerable to infection.
Some causes of dry skin include:
|
|
11.What are cold sores and their causes?
|
|
Eighty percent of the population suffers from cold
sores, also know as "fever blisters" and one-third experience
recurrent outbreaks of cold sores.
A variety of factors can contribute to this virally related condition including over exposure to UV light, illness or fever, menstruation, physical or emotional stress and fatigue, and certain foods and medications. Usually found on the inside and/or around the mouth or lip area, the cold sore while initially blisters, can eventually turn into a painful ulcer. |
| 12.What exactly is a suntan? |
|
A suntan is caused by an increase in melanin, the pigment
in your skin. Melanin gives skin its natural color. The more melanin,
the darker the skin’s color. When UV rays contact the skin, a special
type of skin cell makes and releases more melanin. This is a defensive
response, as melanin can partially protect the skin from some of the harmful
effects of the sun. But remember: there’s no such thing as a safe
tan! A tan is a sign that some cells in your skin have already been injured
by the sun. It’s your skin’s attempt to prevent further damage.
