Before buying another miracle means "quick and easy" to get rid of acne, let's see what the facts are scientifically proven, and which one of those "old wives' plots."
1 Diet and acne.
"In 60-70 years were held invalid studies that have found that chocolate is not associated with the appearance akne.- says Jennifer Burris, a doctoral student of medicine at New York University and author of the Journal of the Academy of Nutrition.- These studies were so popular that people have come to the conclusion that diet acne is not treated, and this statement lasted the last 40 years. "
Today, scientists say the opposite. For example, Dr. Burris and her team examined 200 people and found that those who ate more sweets, dairy products and fatty fish and neglected, were likely to have acne moderate to severe
2 If you are suffering from acne, you should not eat chocolate.
Although the link between acne and diet is proved, to deny yourself the pleasure to eat chocolate is not necessary. "In fact, any food with a high glycemic index may increase the blood levels of cortisol and aggravate acne," - says Mona Gohar, MD, clinical associate professor of dermatology at Yale School of Medicine. - Some of these foods include sweets, bread and pasta. Refined carbohydrates lead to a sharp rise in insulin, which leads to increased production of sebum and clogged pores. "
Good news! You can eat chocolate! "The problem is not in the cocoa and sugar and milk, which are added to the shokolad.- says Marguerite Germain, a dermatologist in Charleston, SC - It is better to eat dark chocolate with a cocoa content of 70% and above.
3 Acne - a teenage problem.
In fact, a survey of over 1,000 adults, published in the Journal of the American Academy of Dermatology found that 50% of women aged 20 to 29 years, 35% of women between 30 and 39 years, and 26% of women between 40 and 49 have acne ( Note: adult acne is more common in women than in men)
"You can blame the surge of hormones that you experienced as a teenager. The level of estrogen in women suffering from teenage acne, increased during the period menstruatsii.- says Dr. Gohar - The hormone increases the activity of the sebaceous glands, which ultimately can cause bacterial inflammation and acne. "
4 Makeup aggravates acne.
It is true that some types of makeup can clog pores and, ultimately, cause of acne. However, the right makeup can improve skin condition. Dr. Gohar suggests using powdered based on mineral base with ingredients such as silica, titanium dioxide and zinc oxide. "This powder absorbs sebum" - she says.
If you prefer a liquid tone, then make sure it nekomedogenen. "This means that the product complies with the standard makeup that does not cause the formation of acne," - explains Dr. Gohar.
5 Sunscreen clog pores.
In the first time, you should choose a cream with low sun protection. There are two types of sunscreens: chemical sunscreens which absorb UV light (common ingredients: oxybenzone and avobenzone), and physical sunscreens which reflect UV rays (common ingredients of titanium dioxide and zinc oxide). While some chemical sunscreens can irritate the skin, causing inflammation and acne, physical sunscreens can even help.
"Zinc oxide, the active ingredient in physical sunscreens can kill the bacteria that cause acne," - says Dr. Germain.
6 The stronger the effect of the drug, the better.
If you spend more than 30 seconds to study drugs from acne at the drugstore, you'll know that they all consist of benzoyl peroxide and salicylic acid. And this is understandable. Salicylic acid unclogs pores and benzene peroxide kills bacteria.
According to a survey Expert Opinion Pharmacotherapy, there is no difference between preparations containing 2.5% benzene peroxide or 10% of the material. Except that a more concentrated formulation may cause skin irritation.
7 . Acne can be derived using the toothpaste.
"Toothpaste consists of baking soda, hydrogen peroxide, alcohol, menthol, essential oils and triclosan, which can dry up pimples," - says Dr. Gohar. - But it's not for your skin because it can cause irritation and rash. "
8 Sun eliminates acne.
"Here's the thing: exposure to sunlight may reduce inflammation in the body, and because of acne - is an inflammatory process, you will see an improvement, - explains Dr. Zhermen.- But do not forget the hat from the sun: with time sun destroys collagen - a protein that makes skin elastic, supple and young. When collagen breaks down, the pores expand and there gets fat. This can lead to the formation of acne. Plus, sun-damaged skin is restored harder, which increases the risk of acne scars. And about skin cancer should not be forgotten. "
9. Acne are due to contaminated far.
"Acne has nothing to do with dirt," - says Dr. Germain. Renewal of skin cells - a natural process that cleans your pores from fat. When this does not occur quickly enough, the pores become clogged with fat and protein solids. Dirt is not being. Therefore, the black dots eliminates retinol. "It accelerates the regeneration of skin cells, keeping pores clean" - says Dr. Germain.
10 Pimples appear due to the fact that you wash your face a little.
It would be great if you could wash away acne at the end of the day. "Excessive washing can actually make the problem worse, - says Dr. Gohar. - When you wash your face too often, you are depriving the skin of the natural fat It makes the skin dehydrated, and to compensate for the loss, the body starts to produce a lot of sebum that clogs the pores. I recommend to use first morning benzene peroxide, salicylic acid is then applied and after - a light moisturizer. Hours cleanse the skin better gentle detergent (to avoid those that contain exfoliating granules or sodium lauryl sulfate, which can cause irritation), and further impose cream with retinol. Use benzene peroxide and salicylic acid is again not necessary.
11 Humidifiers cause acne
Recall again the doctor Gohar, who spoke about what to dehydrated skin pores are clogged with fat faster than hydrated. Therefore, apply to the face a light moisturizer every day and your skin will look more clean and healthy.
12 Chlorine treats acne.
It may seem that swimming in the pool dries your pimples, as well as toothpaste. "Chlorine can not only dry up acne, but also cause irritation that aggravate acne. ", - Says Dr. Gohar - After the pool it is necessary to wash off chlorine and use a moisturizing lotion to clean dry skin."
13 Acne need to squeeze.
Hands off! "Whitehead will go for three days, if they do not touch. But it may take a month if acne squeeze - says Dr. Germain. - Plus - skin is injured, which may lead to inflammation and infection. "
We know how difficult it is to resist the desire to squeeze these nasty acne, but, after all, instead it is better to treat acne benzene peroxide.
14 Acne on the body should be treated in the same way as on the face.
"on the body and on the face of the substance absorbed differently" - says Dr. Germain - This is because the follicles on the body, through which the active ingredients are delivered into the skin, are at a greater distance from each other than on the face. Therefore, even the best antibiotics may not work. So you'd better consult a dermatologist about the method of treatment, and then diet.
15 Shampoo hair does not affect the state of the skin.
Quite the contrary. Fat with hair can regularly get on your face. Solution for clear skin - Avoid shampoos and balms with petroleum jelly or oil. It is better to select water-based product.
16 Stress can cause acne.
Pimple that has surfaced in time for the day of your svadby- it is not a coincidence. "Stress creates hormonal imbalance in the body that can cause acne," - says Dr. Germain. According to research conducted at Wake Forest University School of Medicine, 23% of adolescents have a more severe form of acne. The researchers suspect that stress-induced acne can also affect adult men and women.
