Skin Care: is possible that dermatology is the medical specialty on which circulate more hoaxes and false myths, especially regarding the care of the skin. Let’s talk about some of the best known.
In particular, everything that has to do with the cosmetics of the skin and hair is a very favorable ground for speculative and unscientific opinions. We detail a series of myths that exist about skin care.
The possible relationship of acne with diet has been studied for decades. Today we know with certainty that acne is a normal process in adolescence. It has to do with a time in life when hormones and growth cause excess oil on the skin and clogging of the pores.
Some cases of acne with more inflammation may need treatment because of its unsightly nature and because they can cause scarring. We know that the main cause of this acne is genetic, and has to do with a way of being of the hormonal system and the skin in people with a family history.
Other factors that may influence the development of severe acne are external enhancers such as stress and some elements of the diet, although they have a role that is probably not relevant or controversial. Above all, we refer to foods with a high glycemic index such as milk or sweets (pastries, cookies, sugary chocolate, etc.).
That is, it is not fatty foods, but those that have a high content of rapidly absorbed sugars, which have the capacity to increase insulin production. As these foods should be taken in moderation and should not be the basis of a healthy diet, avoid them in children and adolescents is the rule to follow.
Everyday hair is removed that is replaced by a new one so that seeing hairs in the shower is the most normal thing. Some people believe that washing excess hair can make it fall more, and it is a misconception. The truth is that with each daily wash we make it easier for the hair that has to fall to do it, and we realize its fall.
Another myth is that wet hair “rots” and weakens, but it is another misconception. In fact, aggressive hair drying with high-temperature dryers can denature and break it. Like everything in this life, the best is the middle ground. A hair washes every day or every other day is the right thing for most people
Sometimes gluten intolerance is attributed to problems that are not necessarily proven. The only skin disease that is associated with celiac disease or gluten intolerance is a rare blistering disease called dermatitis herpetiformis, which causes itching and blisters. For the rest, the only external sign of a person with celiac disease can be a consequence of possible malnutrition in extreme cases in which the patient is not feeding correctly.
In this situation, which is very rare to see, the skin may manifest dryness and the hair and nails may be weaker and brittle.
Actually, the dermo cosmetics industry and anti-aging creams live from unscientific myths and hoaxes, taking advantage of an avid market by miracle products that promise what they can not meet. A good “anti-aging” cream should provide hydration to the skin and sunscreen, but probably the rest of the molecules it contains, including vitamins or antioxidants, have no scientific basis.
It is more beneficial for skin care a healthy lifestyle, that avoids tobacco (it is a well-established cause of skin aging and wrinkles), and promotes the consumption of fresh fruit and vegetables. It is not necessary to spend the money on “miracle” creams.
One of the false assumptions about beauty products is that they have to “nourish” the skin and hair with vitamins and minerals of all kinds. It is clear that applying vitamins on the skin does not achieve anything since they are not absorbed or used. The skin and hair are generated “from within“, and the healthy aspect is not achieved by providing them “from the outside”.
All dermo-cosmetic products have to contain preservatives because otherwise, it would not be possible to pack them and market them. That said, there are preservatives with more or fewer advantages and disadvantages, and very thorough health checks are always followed to ensure that they are safe for health.
Parabens do indeed have the capacity to cause allergy problems and are possibly harmful at very high doses, but not at the doses at which they are used as preservatives. The myths that have linked them to breast cancer are false, and this is what the health agencies have assured.
It is common knowledge that the calcium in the bones needs vitamin D to fix and ensure proper mineralization. Vitamin D is produced in the skin under the action of sunlight, and it has been speculated that protecting the skin from the sun to prevent skin cancer could lead to very low levels of vitamin D.
Actually, the issue is much more complex, since in Western countries vitamin D is always at very low levels during the non-sunny months of the year, since our life has stopped developing abroad and we tend to live and work in closed environments with artificial light that does not contribute to producing vitamin D.
On the other hand, an exposure of only 15 minutes in the street light on the face and hands is enough to produce all the vitamin D needed. There are even studies that have shown that by applying photoprotectants, enough vitamin is made. Therefore, it seems reasonable to look for outside light sparingly in winter or take vitamin D supplements if the doctor recommends it, and protect the skin from the sun in summer without the need to worry about osteoporosis.
What you should know…
Believing that washing excess hair can make it fall more is a misconception. With each wash, we make it easier for the hair that has to fall to do it, and we see its fall.
The main cause of the most aggressive acne is genetic, and it has to do with a way of being of the hormonal system and the skin in people with a family history, not of the diet.
Apply products with vitamins on the skin does not get anything, because they are not absorbed or used. Skin and hair are generated “from within”, and their healthy appearance is not achieved by providing these nutrients “from the outside”.
