Carbonated beverages like cola usually contain phosphoric acids, caffeine, large amounts of sugar, and other chemicals. These may add excess calories (if not diet), be dehydrating, and studies have shown that phosphoric acid in excess actually pulls calcium from bone making you more prone to developing osteoporosis.

But what about carbonated beverages that are caffeine-free and low sodium like club soda or Fresca? Sure, a cold, fizzy drink can be very refreshing, especially in hot weather or after a work-out.  But is there such a thing as too much?

The answer is: Yes.  Because carbonation usually causes a feeling of fullness or bloating, you may not be getting adequate fluids to rehydrate your body. The human body’s mechanism for thirst detection is very poor. Therefore, we have already been dehydrated for sometime before we feel thirsty.

Companies like Gatorade have not carbonated their products because it causes gastrointestinal distress and inhibits sufficient hydration.  Because our bodies are composed of 70 percent water, dehydration can have serious adverse effects on bodily functions and even be fatal. On a smaller scale, our skin is affected many different ways when we do not hydrate it properly. Things like age spots are partially caused by the skin being dehydrated.

When your skin is dry, you will lose the elasticity and resilience or the ability for the skin to return to its original state after pressure is applied. Due to our aging process and environmental stress the resilience or tension and elasticity of our skin gradually deteriorates and then we begin to see the appearance of age spots and wrinkles.

There is no reason to completely eliminate caffeine-free carbonated beverages from your fluid intake.  Just consume in moderation and make sure you are drinking 8 ounce glasses of non carbonated/caffeinated water per day to properly hydrate your body and skin to keep you living longer and looking better!

The Fourth of July weekend is here and whether you’re planning a barbecue at a park, the beach or in your own backyard, don’t forget the sunblock. Sunblock is a major factor in protecting you from getting skin cancer from sun exposure.  According to The Skin Cancer Foundation, “more than 90 percent of all skin cancers are caused by sun exposure and sunscreens are a key weapon in the arsenal against the disease.” 

So, here are some of the answers to what people want to know about sunblock.
 
What makes the sun harmful?
 
There are two types of ultraviolet (UV) radiation that the sun emits.  They are UVA and UVB rays.  UVB rays are the rays that cause sunburn.  UVA rays penetrate the skin more deeply and cause long-term damage, such as wrinkling, leathering, sagging, and other effects of aging.
 
What is the UV Index?
 
The UV Index provides a forecast for the risk of overexposure to the sun.  Knowing the UV Index gives you an idea about the dangers of overexposure to the sun when you are working or playing outside.  It is calculated on a daily basis by the National Weather Service and the Environmental Protection Agency.  The measurement is based on the clouds and local conditions that will affect the amount of UV rays to hit the ground. 
 
It ranges from zero to 10+.  Zero implies a low risk of overexposure to the UV rays of the sun and 10+ is a very high risk of overexposure.  For the average person, a UV Index of 3 to 5 is a moderate risk of overexposure to the sun
 
How can we protect ourselves from the harmful effects of sun?
 
o Limit your exposure to direct sun, i.e., spend time in the shade.
o Wear protective clothing if you’ll be in the sun for along periods of time, especially, a wide brim hat.
o Whether you’re in the direct sun or in the shade, use sunblock with a SPF of 15 or higher.

What is SPF?
 
SPF is an acronym for Sun Protection Factor.  It is laboratory measurement of a sunscreen’s ability to filter the UVB rays to prevent sunburn.  The higher the SPF, the more protection it provides against the sun.  In other words, if you burn in eight minutes and you use a sunblock with a SPF of 10, it will take you 80 minutes to burn.  If you use SPF 15, it will take 120 minutes for you to burn. 
 
In reality, the protection provided depends on several factors:  The person’s skin type, the amount applied and the frequency of application, activities that are engaged in while the product is on, and amount of sunscreen that is absorbed into the skin.
 
How should you apply sunblock?
 
Frequently and liberally!  Despite the fact that it adds hours on to the time it takes for a person to burn, it is best to apply it at least every two hours.  Apply it more frequently, if you are swimming or sweating.  It should also be applied liberally — one ounce per use.  Therefore, if you buy an 8 ounce bottle, it should only last for 8 uses.
 
Which is the best number to get?
 
Anything above SPF 15 is best.  SPF 15 will filter out 92 percent of the UVB rays, SPF 30 will filter out 97 percent of the rays and SPF 50 will filter out about 98 percent. 
 
Whatever number you get, remember to apply it frequently and liberally!
 
What is the best kind to get? 
 
It does not have to the most expensive one on the shelf to be the most effective.  You should look for ones that filter the UVA and UVB rays.  Look for ones that are waterproof or sweatproof.  Needless to say, take waterproof and sweatproof with a grain of salt.  If you go swimming for more than a quick dip and you’re sweating more than a droplet on your forehead, it’s not enough to apply it once.  If you go swimming, apply it again when you come out of the water.  If you’re sweating, apply it more frequently.
 
Are there clothes that have SPF?
 
A regular white T-shirt has an SPF of 3.  There are clothes that are made with zinc oxide and can provide an SPF of 30.  Tighter knit clothing also provides some protection.  Always try to wear a wide-brim hat to give more protection too. 
 
Am I protected from the UV rays in the shade?
 
The shade does provide some protection but the UV rays of the sun can reflect off the water, sand, concrete, and snow (not usually a problem in the summer!) and then penetrate the skin.  So sitting in the shade does provide good protection, but you still need to apply sunscreen.
 
And remember, whether you’re walking on the beach or just sitting on the porch reading a book, it’s always a good idea to have a bottle of sunblock close by. It’s a key factor in reducing your risk of developing skin cancer.

The Food and Drug Administration, which has received criticism in the past for allowing risky devices like electronic muscle stimulators to go into the stores uncontested, has just given its approval for Palomar Medical Technologies to go over-the-counter with its light-based LED laser. This new toy uses a light-emitting diode to supposedly stimulate normal skin growth and reduce wrinkles.

I spoke to three top dermatologists at NYU Langone Medical Center — which has one of the top dermatology programs in the world — and all three said the same thing. They said the laser was most likely quite safe, and it’s very unlikely it will damage the eye — but it is not likely to be effective, is expensive, and may only remove the tiniest wrinkles with prolonged use 20 to 30 minutes, twice a day. So in evaluating the FDA’s performance here, score one for safety, but zero for effectiveness and cost. And don’t expect National Health Insurance to cover the cost of this one.

If you really want to help your skin and decrease your chance of wrinkles, then use sunscreen, eat and sleep properly, exercise and don’t smoke.

Dermatologists are now using new kinds of lasers to remove wrinkles, known as fractionated CO2. These are VERY effective, but can only be done by highly-trained doctors.

If you are serious about your wrinkles, (or have to appear on High Definition TV) see your dermatologist. Do-it-yourself lasers that are now being marketed for home use may be used for attacking the tiniest wrinkles, but should not be a primary treatment. The FDA needs to crack down on the devices they approve. This one is okay, except that it is expensive (several hundred dollars) and largely placebo.

In today’s world, there are so many ways to fight the lines of time. But by far, one of the most popular is Botox.

Botox is basically a neurotoxic protein produced by the bacterium Clostridium Botulinum.  It was originally used to treat muscle spasms — but in 1997 it earned FDA approval for cosmetic treatment.  The American Society of Plastic Surgeons (ASPS) reported that there were more than 2.8 million procedures performed with Botox in 2008.  (Just more proof about how wildly popular this anti-wrinkle treatment is.)

A Botox Cosmetic injection can do a few things. It can help soften the overall look of your face and reduce the animation in some of the muscles in the upper part of the face. (This results in a younger, more youthful appearance.) It can also treat facial lines caused by repetitive muscle movement, which we frequently do in my practice. We also use Botox to help prevent new lines from forming. Common injection sites for erasing wrinkles and lines include:

• Glabella (region between eyebrows)
• Forehead
• Outer corners of eyes (crow’s feet)
• Either side of mid-chin, for down-turned mouth
• Neck, for neck bands or visible chords

We also use Botox to treat:

• Facial asymmetry or other facial conditions that result from muscle action; this is called “facial shaping”
• Hyperhidrosis (excessive perspiration); common injection sites are underarms, palms, scalp and soles of feet

Remember — An experienced injector makes all the difference

Today, people often take the wrong shortcuts when seeking facial rejuvenation with Botox and other injectables. If the injector administers too little Botox Cosmetic, the results will not be fully visible. However if the injector injects too much, the appearance can be a frozen or stunned look. On occasion there may be some unevenness, meaning that one brow is higher or lower than the other. This is easily corrected with a touch-up or the patient can wait for the toxin to lose its effect. Usually the patient will look better within a few weeks.

Keys to successful Botox Cosmetic treatment include going to a doctor that injects regularly.  Also, it is important to articulate to the physician your exact goals. For example, if you want your eyes to be more open, to look less tired or to raise your brows, be specific. It is always my advice to seek a more natural look and have some animation.

Alternatives?

In the battle against aging, there are several alternatives to Botox Cosmetic.  One such option is GFX, a radiofrequency procedure that lasts approximately 1 year or more. This is due to ablation of the nerves which cause muscular contraction of the glabella — more commonly known as the region between the eyebrows.  Other options include Reloxin and Puretox — neither of which is FDA approved.

In today’s economy, we are all looking for affordable but effective ways to keep skin looking its best.  From the dollar store to the department store, there are many products available.  The reality is that most of them are great.  There are, however, home alternatives which often times don’t require a shopping trip.  Not only do these alternatives work, but they are also fun and simple to create.

TREAT ACNE
Acne can be one of those persistent problems, popping up at the worst time.  We’ve all had these flare-ups, which include pimples before a big party or that pimple that appears just before an important date.  The best at home treatment for acne is a warm compress, consisting of a washcloth and some warm water. 
Then follow these steps: 
1. Apply the warm washcloth to the pimple or acne-prone area
2. Hold the compress on for 3-5 minutes, continually warming it up as necessary, to maintain a warm feeling on your skin  
3. Be sure not to use water that is too hot — not only will it burn the skin, but it won’t do any good in treating the acne   
4. Repeat the compress every 2-4 hours until the acne disappears.  Depending on where you are in the acne breakout, your acne should clear up within 24-36 hours  

For an inexpensive product that can be used in conjunction with this remedy I suggest Unblemished Treatment Concealer by Beauty Benefits. 

UNCLOG BLACKHEADS
Not many faces are blackhead free… To help rid your skin of these, use oatmeal and rose water to create a soft paste.  Cover blackheads with the paste and rub it into your skin.  Wait 15-20 minutes and then rinse away.  You can also use this oatmeal mask all over your face for a radiant glow.  

If you are in a rush, and don’t have time to create the paste, simply head to your nearest drugstore and purchase Neutrogena Healthy Skin and Neutrogena Healthy Skin Anti-Wrinkle Anti-Blemish Scrub. 

CLEANSE AND EXFOLIATE
For an affordable but effective skin cleanser and exfoliator, I recommend creating a solution of sugar and water.  Before putting the solution on, open pores by first leaving a warm cloth over your face for a few minutes.  Rub the water and sugar solution gently into your skin and then rinse.  This does a great job and will leave your skin clear, clean and refreshed.

For a more aggressive exfoliator, mix in sea salt instead of sugar.  This can be used to exfoliate your entire body and works great on those annoying rough spots like feet, knees and elbows.

Not interested in making it yourself? Pick up St. Ives Apricot Scrub.  It’s a solid alternative.

ALLEVIATE DRY SKIN
Take a quick trip to your pantry and pull out a bottle of olive oil … Olive oil was good enough for the ancient Greeks and it’s good enough for you, too.  The ancient Greeks used olive oil to bathe and to moisturize dry skin.  Almost every vegetable oil is compatible with the skin.  Apply just after bathing to moisturize and protect dry skin.  Use it daily to help reduce dry patches and the appearance of stretch marks. 

While I recommend olive oil for any skin, if you insist on store bought, try good old Coconut Body Butter.

HYDRATE
Drink water every day.  We know it’s good for us in every way.  It makes your skin look great, too.

NOURISH YOUR SKIN
Facial masks can be fun and help rejuvenate your skin.  Try making one at home.  A honey mask is a great way to brighten and lighten your skin.  Mix one tablespoon of honey, one egg yolk and one teaspoon of olive oil together.  Beat the egg yolk first and then add the oil and blend well.  Add the honey with a spoon rinsed in hot water and blend well.  Apply this honey mask to your face, avoiding your eye area.  Leave on your face for 20-30 minutes and rinse.  The difference is visible.

A great alternative to the honey mask is The Original Mint Julep Masque available at almost any drugstore.

TONE AND TIGHTEN
NE Witch hazel, available at any drug store has been the main ingredient in most toners and is not irritating to the skin. It still works great on its own.  Gently wash your face.  Pat your skin dry and then apply witch hazel with a cotton ball.  If you have dry flaky skin, try diluting the witch hazel with two parts water.  Since witch hazel is an astringent, always moisturize after you tone.  Try mixing two tablespoons of witch hazel with one teaspoon of lemon juice and three tablespoons of rose water for a refreshing toner.

Be sure to keep witch hazel at home.  Not only does it do a great job of toning and tightening your skin, but it’s an excellent topical remedy for the treatment of traumatic bruises and bumps and promotes speedy healing.

MOISTURIZE
Moisturizing is essential for your skin not only because it locks in hydration, but moisturizer creates a protective barrier between your skin and the elements.  Making an effective moisturizer at home is not difficult. Take five to six drops of sweet almond oil and add a few drops of water. Mix the two ingredients in your palms, rubbing both hands together then gently smooth the blend into your skin. 

Moisturizing is the bottom line in skincare — almost any moisturizer will do the trick.  Eucerin Extra Protective Moisture Lotion with SPF is a great body moisturizer and it is available at most drugstores nationwide.

SOOTHE
From time to time you may find your skin red and irritated.  Taking care of red, irritated skin at home is as easy as a glass of milk. It doesn’t matter if you prefer cow’s or soy milk ― they both get the job done.  Soak a wash cloth in milk and then apply the cloth to the effected area.  Leave on the skin for at least five minutes.  Repeat as often as necessary depending on the irritation.  Milk sooths and calms the skin and helps to promote healing while softening and nourishing the skin.

For the store bought alternative, try an aloe vera gel.  It’s cooling to the skin and aloe naturally helps promote healing. 

MINIMIZE PORES
Our pores are an open target. They collect oil and often get clogged, causing the pores to appear larger than we want.  The easiest treatment option is actually free.  Run hot water into a stopped sink or a large bowl. Drape a towel over your head and lean over the steam.  Using the towel helps to trap in the rising steam.  Gently cleansing the skin or gently exfoliating the skin helps minimize the appearance of clogged pores.  Pat skin dry and use a toner to tighten and refine.

A great option that you can purchase in the store is Neutrogena Pore Minimizing Mask.  It will minimize the appearance of your pores and refresh your skin.

Plasma Portrait™ is a laser technology that delivers noticeable results by reducing pigmentation, improving fine lines and wrinkles, and perfecting skin’s tone and texture. In addition to leaving skin looking younger and refreshed, Plasma Portrait can also be an effective treatment when used to correct acne scars.

This industry-leading technology is used in a similar fashion to other ablative lasers (which destroy layers of the skin) such as the CO2 and erbium lasers, and new generation fractional technologies (which provide deep heating of the skin) to correct wrinkling, pigmentation, skin smoothing and acne scarring. 

Based on a principle similar to plasma televisions in that it converts plasma into activated nitrogen which acts to gently heat the skin, Plasma Portrait technology has been used in medicine for many years. The advantage of Plasma Portrait over other laser technologies is that it allows the skin to repair itself in a shorter time frame. This leads to less side effects and shorter healing time than experienced with more invasive laser technologies.

Employed under local anesthesia, such as topical anesthetic creams, Plasma Portrait technology can also be used in various treatment modes including a single, high-energy treatment for more significant wrinkling skin pigmentation, skin surface irregularities and skin cancers. Plasma Portrait can also be used at lower settings where up to three treatment sessions can be performed. Under this modality, some patients experience almost no downtime or just a day of mild redness. The high-energy treatment, however, may have three to five days of a minimal sunburn-like reaction, as this technology leaves a layer of skin on the surface intact which acts as a natural wound dressing.

Plasma Portrait is playing a major role in the dermatologic, plastic and cosmetic surgeons’ therapeutic regimens. Associated with significant clinical efficacy and more reliability than many of the non-ablative technologies utilized in the past, Plasma Portrait has become quite popular with patients looking to reduce pigmentation, improve fine lines and wrinkles, enhance tone and texture, and correct acne scars.  With this treatment, skin looks younger and refreshed.
