Five mistakes you must avoid while using sunscreen!

Many people remain confused and make mistakes when it comes to the use of skincare products, particulary sunscreen. While people belonging to the ethnic dark-skinned groups think that they do not need sunscreen, fair-skinned people too commit blunders, which in turn can increase the risk of melanomas.

Five mistakes you must avoid while using sunscreen!

Below are five common sunscreen mistakes that all of us make:

  • Using little sunscreen: Do not be stingy with the sunscreen, apply a sufficient amount of it on those parts of your skin which are often exposed to the sun such as face, neck, hands, arms and feet.
  • Not reapplying often enough: Even if you wear a water-resistant/sweat-resistant sunscreen of SPF 30, you should reapply your sunscreen every 2-3 hours, especially after swimming or perspiring.
  • SPF values: Many people think that SPF values can be added while actually it cannot be. For eg, if you are using a sunscreen of SPF 15 and then of 10, you will not have the added advantage or protection of 25, but will be getting the protection of SPF 15 only.
  • Wearing low SPF while outdoor: If you are going out in the sun, make sure that you wear a high SPF of 30 or above, which is sweatproof and waterproof. However, if you wear a low SPF you should reappy it more often.
  • Using sunscreen that has only UVB protection: Always wear a sunscreen that has protection for both UVB/UVA rays. Because UVA can cause long-term effects such as premature skin ageing whereas UVB can caue sunburn.

How to Have Flawless Skin in a Week

How to Have Flawless Skin in a WeekDetermine your skin type. Is it oily, dry, normal, or combination of either? In order to do this, wash your face, let it dry and leave your face completely untouched for an hour. Inspect by dabbing a tissue between your nose and cheek, called the T-zone:
Normal skin shows neither oil nor flaking skin. It should feel supple and smooth. If you have it, consider yourself lucky!

Oily skin is characterized by the grease on the tissue. It is also common for a person with oily skin to have large pores and a bit of a shine.

Dry skin may feel taut or show flakes of dead skin. It is associated with small pores. Moisturizing is important for this skin type.

Combination skin is most common. It exhibits traits of all three of the above skin types. Usually, the skin is oily in the T-zone and normal to dry elsewhere.

Invest in a cleanser, toner, moisturizer and facial scrub suited to your skin type. (If you’re young there’s no need for a facial scrub.) You might have to test out a couple of brands before you find the perfect one. Talk to an associate at a make up or skin care counter. You will be able to test different formulas. They may even offer samples so you can try a product out for a day or two.
Try to get cleanser, toner, and moisturizer that is non-comedogenic. This just means that it won’t clog your pores, leading to pimples.

If you have a bad case of acne or any other skin problem like eczema, see a dermatologist. They will give you the specific treatment you need. It’s likely that any medication you get from a dermatologist will be prescription strength, too, meaning it will be stronger.

Buy an SPF 15+ sunscreen for daily use. Try for a facial sunscreen with no fragrance or oil. Sunscreen will help block harmful UV-A and UV-B rays that can lead to skin damage and cancers.
Many moisturizers these days have sunscreen built into them. Experiment with different moisturizers to see if the sunscreen works well and the moisturizer keeps your face hydrated.

  • Use your face wash every day. You will not see a difference if you only use it once a week. Use your scrub, which lifts off dead layers of skin, only every few days as to avoid scrubbing off too much skin.
  • Do not use a washcloth, loofah or any other abrasive material to wash your face. Washing with your hands is perfectly acceptable, and will lower the irritation you might otherwise get with an abrasive material.
  • Wash once in the morning and once at night. This is especially important if you have very oily skin, or numerous pimples.
  • Moisturize after every wash. Washing your face with a facial cleanser sucks all the natural oils from your face. Clear, beautiful skin is hydrated skin.

Wash off your makeup. Before going to bed remember to take off any makeup you put on. Washing your face may do the trick, but some makeup may require makeup remover.
Don’t be lazy about taking off makeup. If you’re prone to leaving your makeup on or forgetting to wash your face, invest in some wipes and keep them close to your bed. That way, all you need to do is swipe your face when you’re dead tired.

Eat properly. A great menu is a balanced menu. Remember the food pyramid? Eat fruits and vegetables. Nutritionists recommend eating 3 servings of fruit and 5 servings of vegetables daily. Avoid foods with caffeine and sugar, as well as greasy foods and red meat.

Drink plenty of fluids. Try to drink 8 glasses of fluids, preferably water, every day! Avoid sugary soft drinks, caffeine and coffee. Green/herbal tea is rich in antioxidants, which protect cells in your body from damage.

Exercise. Exercising helps you metabolize. A walk with your dog or some yoga lessons do make a difference! Healthy skin is just another part of a healthy body.
Exercising is also good for relieving stress. Studies show[1] that there’s a link between how stressed you are and how bad your acne is. So if you’re super-stressed all the time, try your favorite form of exercise to get rid of it pronto.

Sleep. Make sure you get your 8 hours every night, perhaps a bit more if you are a teenager. Being well rested gives your body more energy to go about its daily routine, and leaves you feeling even better. Flawless skin doesn’t have big dark circles.
Do this every day, and you will soon begin to see the results.

Sunscreen that protects DNA from UV rays

Sunscreen that protects DNA from UV rays

The experiment at the Department of Energy’s SLAC National Accelerator Laboratory focused on thymine, one of four DNA building blocks.

Ever heard of a molecular sunscreen? It is a defence mechanism that the molecular building blocks that make up DNA mount to prevent the damage by ultraviolet rays, reveals new research.

The DNA forming molecules absorb ultraviolet light so strongly that sunlight should deactivate them. But a “relaxation response” protects these molecules and the genetic information they encode from UV damage, the researchers said.

The experiment at the Department of Energy’s SLAC National Accelerator Laboratory focused on thymine, one of four DNA building blocks.

Researchers hit thymine with a short pulse of ultraviolet light and used a powerful X-ray laser to watch the molecule’s response.

A single chemical bond stretched and snapped back into place within 200 quadrillionths of a second, setting off a wave of vibrations that harmlessly dissipated the destructive UV energy.

Researchers had noticed years ago that thymine seemed resistant to damage from UV rays in sunlight, which cause sunburn and skin cancer.

Theorists proposed that thymine got rid of the UV energy by quickly shifting shape.

But they differed on the details, and previous experiments could not resolve what was happening.

“As soon as the thymine swallows the light, the energy is funnelled as quickly as possible into heat, rather than into making or breaking chemical bonds,” said lead researcher Markus Guehr from Stanford University in the US.

“It is like a system of balls connected by springs; when you elongate that one bond between two atoms and let it loose, the whole molecule starts to tremble,” he explained.

The findings appeared in the journal Nature Communications.

Doctors doing little to promote sunscreen use

Doctors rarely talk to patients about using sunscreen, even when patients have a history of skin cancer, according to surveys of U.S. physicians over two decades.

Despite professional guidelines encouraging doctors to educate their patients about sun protection, in more than 18 billion patient visits from 1989 to 2010, sunscreen was mentioned less than one percent of the time.

Even dermatologists managed to mention sunscreen in less than two percent of visits, researchers found.

“The rate of discussing sunscreen at visits, especially for high-risk patients with cancer or pre-cancerous lesions, was lower than we would have expected,” said one of the study’s authors, Scott Davis, of the dermatology department at Wake Forest School of Medicine in Winston-Salem, North Carolina.

The survey data may not capture all mentions of sunscreen with complete accuracy, but that does not change the conclusion that frequency is much too low, Davis told Reuters Health.

Failing to mention sunscreen often enough is contributing to excessive unprotected sun exposure, especially for children, that will lead to skin cancer later in life, he said.

Davis and his co-authors examined data from an ongoing annual government survey that asks randomly selected doctors representative of their areas to record their patient interactions in detail for one week.

Over the two decades of the survey, there were about 18.3 billion patient visits to outpatient physician offices, and based on doctors’ survey responses, sunscreen came up at less than 13 million of those visits, which is 0.07 percent.

When visits specifically concerned skin disease, doctors still mentioned sunscreen less than one percent of the time, according to the results published in JAMA Dermatology.

Dermatologists talked about sunscreen more than any other specialty, at 1.6 percent of all visits and 11.2 percent of visits involving a patient with current or past skin cancer.

“I don’t think the results are surprising, at least not for someone who is familiar with what research has said about skin cancer counseling practices,” said Dr. Jennifer S. Lin, who studies evidence-based healthcare decision making at The Center for Health Research of Kaiser Permanente Northwest in Portland, Oregon.

“It is certainly disappointing,” said Lin, who has conducted reviews to support the U.S. Preventive Services Task Force for the past seven years, but is not herself part of the USPSTF.

In the study, Davis and his coauthors found that doctors mentioned sunscreen most often to white patients, and to those in their 80s, but least often during visits by children.

Evidence supports UV and sun protection counseling to prevent skin cancer, especially for kids and teens, so extremely low counseling for those groups is “incredibly problematic,” Lin said.

But she cautions that sunscreen is only one part, and not the most important part, of UV protection, which includes avoiding midday sun, wearing appropriate clothing and avoiding tanning beds.

“My belief as a primary care doctor, not based on my research, is that our health system does not value counseling or patient education as much as it does procedures, testing, medications, etcetera,” Lin said.

Even for patients who already know about sunscreen, discussing it can help, Davis said.

As with smoking and unhealthy eating, most people are aware of the risks, but bringing it up during an office visit shows the patient that the doctor is concerned and wants to help change the behavior, he said.

The American Academy of Pediatrics recommends bringing up sun protection at annual checkups, Davis said.

“The fact that it was recommended least frequently to children is very concerning, since children tend to get the most sun exposure, and may develop lifelong habits of poor sun protection,” Davis said. “This may be where physicians have the greatest opportunity to fight the ongoing, growing epidemic of skin cancer.”

Skin cancer continues to be the most common form of cancer in the U.S., diagnosed in more than 60,000 people yearly, according to the Centers for Disease Control and Prevention.

Patients may need to take the initiative and bring up sun protection themselves if they have questions, he said.

“Physicians are pressed for time and feel they cannot take the extra time needed for discussion of preventive care topics,” Davis said.

“But the main thing may be that physicians just aren’t thinking of it. This research may make health care providers more aware of the need to encourage commonsense sun protection, especially for younger patients,” he said.
