Acne. Pimples. Zits. Blemishes. No matter what they're called, acne has affected many people- adults and teenagers alike. Acne typically affects anyone, of any race, and at any age, be it 10 or 40. Although acne is a very common problem many people face (pun intended), its highly visible nature is what makes it such a universal complaint. So much so, that for some people, acne can have a deep psychological impact regarding a person's appearance and self-esteem. Science and technology has made it possible to keep acne at bay, but without an understanding of how acne forms, many people just end up relenting to trial and error when it comes to treating acne.
How acne forms
While reading labels on various lotions and makeup, the word comedogenic (or non-comedogenic) probably pops up. Comedogenesis is simply the clogging of a follicle or pore and usually precedes acnegenesis, or acne formation. Pore clogging typically happens when sebaceous (oil) glands in the skin produce too much oil, and surface skin cells (known as keratinocytes) start to stick together. The amount of oil produced can be due to hormones, such as the case in adolescent acne or acne that is related to the pre-menstrual cycle. The bottom line is that when the pore clogs up, this becomes a rich nutritional source for Propionibacterium acnes (P. acnes), which is the bacterium thought to be responsible for acne formation. Because of this source, P. acnes will start to collect in a specific area. When enough P. acnes gathers together in one spot, say the nose for example, the body kickstarts an immune response to try to purge the bacteria. This results in redness, pus, inflammation, and the resulting mound that many people love to pick at. But don't be a picker!! The nails harbor lots of bacteria, and introduction of such to an area that's already inflamed will only cause more inflammation. Sharp nails also risk irreversible pick scars that will look deep and depressed.
So what can be done to prevent P. acnes from wreaking havoc in the skin? There are various ways of killing P. acnes.
Benzoyl Peroxide
Benzoyl Peroxide (BPO) kills P. acnes due tp oxygenation of the affected pore/follicle. Treatments such as cleansers and lotions that contain a concentration of BPO are effective in reducing P. acnes, but it is important to note that because oxidation causes free radicals, prolonged use of higher concentrations of benzoyl peroxide may eventually lead to accelerated aging of the skin.
Sulfur
Who knew the smelly pink stuff that looks like Calamine would work to dry up acne? Sulfur has a dual action because not only does it have antibacterial properties that kills P. acnes, it's also a good keratolytic that causes the top layers of the skin to loosen and slough off. However, it's important to make sure to do a patch test first to ensure you are not allergic to sulfur, because it's known to cause reactions in some people. Also, using sulfur too often will cause overdrying.
Antibiotics
Antibiotics such as topical erythromycin and clindamycin also target and kill P. acnes. But caution should be used because there may be a likelihood that the bacteria may form a resistance to the antibiotic over time.
Photodynamic Therapy (PDT)
In a previous article, I wrote that various light systems today are used to improve skin conditions such as acne. Specifically, blue light with a wavelength of about 420 nanometers is absorbed by P.acnes, which leads to the excitation of particles called porphyrins that live in P. acnes. As porphyrins are excited, they break down the bacterial walls of P. acnes and destroys them.
Although blue light alone was clinically shown to improve mild to moderate acne, severe cystic acne needs more power punch. A more powerful form of PDT combines LED light with 5-aminolevulinic acid (Levulan). A Levulan swabstick is first applied on the skin, and left on to "incubate" for about 1-2 hours. A patient is then exposed to LED light (with safety eyeshields on) for a few minutes to activate the Levulan. In addition to killing P. acnes through the use of wavelength-specific lights (the photodynamic part), Levulan acts to shut down sebaceous glands that produce excess sebum (oil).
It is extremely important to note that although Levulan has a high efficacy rate in severe acne lesions, it is not for everyone, especially darker-skinned individuals because it has a greater chance of hyperpigmenation (skin darkening) from the treatment. It should also be noted that some may feel a burning sensation after photoactivation, which also has subsequent redness, followed by severe peeling of the skin. This lasts a few days, up to about a week of downtime.
Whatever the degree of acne, these different treatment modalities help to control its effects. So even though acne is not curable, it is manageable. Consulting with a skincare professional will help ensure you look and feel your best so you can put your best face forward!

"Lights, Camera, Action" 3 Keys To Busting The Winter Blues
No, I'm not recommending that you make your own independent film this Winter. Stay with me here and it will all come to light!
Do you literally find yourself getting "sick and tired" at this time of year, and maybe a little depressed as well? You're not alone! 78% of the North American population experiences increased fatigue, stress, illness, weight change and depression during the "blues" months of November to April.
Don't despair! There are simple, easy ways to sail through the season with more JOY, CHEER and EASE!
Lights:
It's no accident that the Winter holidays involve lights…,,,the Jewish Menorah, Christmas lights and candles, etc. When the days are shorter with less light, seratonin levels go down and depression levels and weight tend to go up. Studies have shown that the "winter blues" or SAD (Seasonal Affective Disorder) is caused by less sunlight rather than temperature changes. So what's the solution? Here are a few.
1.Get as much real daylight as you can. If you work inside and especially under fluorescent lights, take your breaks outside. Take a quick walk outside at lunch. Park a distance from your destination. Even a few minutes of being out in the daylight can make a significant difference.
2.Use full-spectrum lighting in your home and your office. I often recommend that clients replace the fluorescent lights at work with full-spectrum bulbs whenever possible. I used to get migraines almost every year starting in early November. No more! I put daylight halogen lamps in my office, living room and bedroom and….VOILA! No more migraines. The minor cost of keeping the lights a little brighter at night and in the early morning is well worth it. Whatever you do, avoid sitting in a darkened room watching TV or at the computer. Keep the lights on.
Camera (not really):
Think of your mind as a camera, as your own on-going video or movie. Our subconscious and nervous systems do not distinguish between physical reality and our imaginations. So visualize, visualize, VISUALIZE!
1.Take a few minutes each day or throughout the day to close your eyes and see the entire inside of your body full of light, every cell lighting up. Any internal or external images of light will work. See yourself at your favorite beach with sunlight drenching every inch of your body. See yourself playing tennis or any other warm weather activity on a sunny, summer day. You're the director here. You get to be anywhere you want, doing anything you love. In your mind, fill yourself and your surroundings with light. This is POWERFUL!
2. This part is so important that it gets it's own number. When you visualize, FEEL! Feel all the physical sensations and emotions that you would if you were really in the place or situation you are imagining….the warmth, the movement, the freedom, the contentment, the deLIGHT! Using all our physical senses and emotions creates a much more powerful physiological and psychological response to mental images.
Action (really):
Even without the "blues", our bodies and metabolisms tend to slow down in the winter months. It's only natural. And, of course, there's all that Holiday eating! You know that you're going to over-indulge at this time of year. You always do (and you're in good company – the rest of us!)
1.Be pre-emptive. Start increasing your activity now, before the major eating begins.
Add 5 minutes to your treadmill time or any workout time. If you're not exercising, start!
Do some side and back leg lifts while you're standing at the stove or waiting for the microwave. (I do this compulsively now, and my thighs and behind are very grateful.)
When you come home, go up and then down and then up the stairs again…with the groceries or shopping bags.
When Holiday shopping, park at the far end of the parking lot (like you have a choice!) You'll get more exercise and daylight.
Take a walk with the family or friends after that big holiday meal or party.
"When you get the chance to sit it out or dance, I hope you DANCE."
2.Whatever you do, don't compound the over-indulging with beating yourself up
about it. If you're like the rest of us, you are likely to gain a few pounds over the winter. Big deal! EnJOY yourself, and just do what you can, when you can.
A quick note about that upcoming New Year's resolution to lose the holiday weight:
Winter is by far the worst time of year to try to lose weight. It goes counter to your body's natural rhythms and tendencies. (Think hibernation!) Rather than setting yourself up for failure, do what you can to avoid the weight gain to begin with. Staying active before and during the Winter will set up your mind and metabolism to lose the weight more easily when Spring rolls around.
Keep your mind and thoughts LIGHT! EnJOY! Be of good CHEER, and when you want to bust the winter blues, remember…………
LIGHTS, CAMERA, ACTION!

What do FL-D and 81B filter do? Do they help to darken a blue sky?
Do the FL-D and 81B filter help to darken a blue sky?
or what do they do?
Thanks for your sharing!
The FL-D is for colour correcting the light from fluorescent light when using daylight film
81B is used to "warm" the colour of light when using tungsten film outdoors.
What you are talking about is a polarizing filter. It can darken the sky at 90 degrees to the axis of the suns light.
