A number of foreign experts, cosmetologists and dermatologists, have commented on popular claims about skin care. Experts agreed with some of them, but considered some theories completely unjustified.
So, doctors said that the skin can get used to the use of moisturizing cosmetics, and begins to "lazy", ceases to provide itself with moisture. Writes about this MedAboutMe. But, according to experts, the mechanism of self-moisturizing of the skin is too complex to be influenced by cosmetics.
It depends on the production of hyaluronic acid and sebaceous secretions, these internal processes of the body depend rather on genetics. Creams compensate for the lack of moisture in the skin, but only in the upper layer, scientists say.
One theory is that a base tan protects the skin from burns. What do scientists think? In their opinion, the concept of "base tan" has nothing to do with health - the very fact that the skin has changed from a lighter shade to a darker one, speaks first of all about its damage.
You can often hear that acne on the skin does not appear from products, they are provoked by purely internal processes in the body associated with hormones. In fact, they can. This, in particular, was stated by Gohara Mona, associate professor of dermatology at the Yale School of Medicine. According to her, the skin requires a healthy diet, and if certain rules are followed for three months, positive changes in the condition of the skin will become evident. Experts from the American Academy of Dermatology believe that the worst products for the skin are those that contain refined sugar and flour, which can activate inflammation and increased sebum secretion.
Do you also do facial exercises to tighten your skin and look younger? According to the doctor of medical sciences, dermatologist David Bank, facial rejuvenation techniques based on the principle of face lifting are in reality ineffective, and sometimes even harmful. These exercises tone the facial muscles, but they do not affect the elasticity of the skin and its youthfulness. Moreover, regular facial movements can lead to the destruction of collagen - the main "youth protein" for the skin, the dermatologist is convinced.
Certain cosmetics can help fight cellulite. How many cellulite creams and scrubs have you already bought? Scientists advise to remember: genetic predisposition, hormones, metabolism, lifestyle are responsible for the formation of cellulite. Any folk and cosmetic products can improve the appearance of the skin as a whole, but cellulite does not go away. Cellulite is a skin condition, not a skin disease.
You need to choose good eye creams that really work and help get rid of puffiness and dark circles. This opinion is often heard. But is an expensive cream really better than a cheap one in this case? Here's what the experts think: Eye cosmetics can be effective if skin problems are caused solely by a lack of rest and sleep. But if the problem of the same edema under the eyes is associated with disturbances in the functioning of the cardiovascular system, gastrointestinal tract, liver and kidneys, even the most expensive cosmetic product will not help.
Dermatologists also commented on the opinion that cool water is good for the skin - it shrinks pores and tightens. They noted that cold water does not in any way affect the size of human pores, which is determined purely by genetic factors. For the same reason, hot water does not expand the pores on the skin.
Another tip is to sleep on a silk pillowcase to prevent wrinkles - scientists were also quite skeptical. Photoaging associated with UV rays contributes to the formation of wrinkles; this is approximately 90% of the external aging process.
Pillowcases made of any other smooth fabric are ineffective as a way to prevent wrinkles, since a person changes his body position many times during the night, and spends a third of the night rest on his back, wrinkles simply do not have time to form because of how he sleeps.
