With cosmetics, it is the same as with food packaging that we find in the supermarket: they often promise much more than they can offer. Just take a walk through the section of any large area to find anti-hair loss, repair or fortifying shampoos that seem like the definitive remedy and, in fact, they are not. Ricardo Ruiz is one of those doctors who do not hesitate to denounce the abuses of large companies and they only marry scientific evidence. “I have no conflicts of interest with the pharmaceutical industry,” says one of the most prestigious oncological and aesthetic dermatologists in our country, director and founder of the International Dermatological Clinic of Madrid.

Ruiz, author of dozens of scientific articles in prestigious magazines, has just presented What your skin says about you (The Sphere of Books), his new book. A work of more than 300 pages in which this doctor explains in an informative way what types of skin cancer exist, how to know if a mole is dangerous or not, why our face ages, what creams you should never use if you are pregnant, what are the characteristics of vitiligo, the disease that your wife suffers from, or what is hidden in the creams, lotions or gels that we find in stores, among other matters.

An informative guide anticharlatanes that, as stated in its subtitle, aims to reveal the “secrets of a dermatologist about the remedies, treatments and advances for a 10 result” and combat the most widespread myths in the collective imagination.

‘What your skin says about you. The secrets of a dermatologist on the remedies, treatments and advances for a result ‘, by Ricardo Ruiz Rodríguez.

Water and skin hydration

One of the most widespread false beliefs is that to have healthy and glowing skin you have to drink a lot of water. “Drinking water does not hydrate the skin”Ruiz writes in his book bluntly. “As much as many media insists that you have to drink a lot of water to keep the skin hydrated, this is not true. The skin is hydrated through the application of creams.”

Actually, as the dermatologist points out a little below, what is achieved with the application of creams on our skin is to avoid dehydration. “Namely, with moisturizers what we can do is control the loss of water through the skin. When the loss of water through the skin decreases, its hydration increases “, he confirms. However, not all products that reduce dehydration of the skin serve this purpose.” If we wrap the skin with a plastic, the loss of water through it is eliminated and the hydration of the skin is so excessive that it is adventure“Ruiz points out.

Dark circles: not only due to lack of sleep

There are many people who think that the appearance of dark circles under our eyelids is due to lack of sleep. It’s true. However, this is not the only reason. “Frequently, alcohol causes dark circles and fluid retention on the eyelids. Also, avoiding alcohol leads to immediate weight loss, “writes Ruiz.

Also rubbing the eyes can favor the pigmentation of this area, as well as the sun’s rays, so Ruiz recommends using glasses and creams to protect the area. “Try injecting a little hyaluronic acid if you have a loss of volume, that is, if the dark circle area is sunken. Be very careful with injecting too much, since this acid attracts water and we can worsen the handbags“, emphasizes the dermatologist.

The lie of hair loss shampoos

Neither are there shampoos that have an anti-hair loss effect, nor are we going to make it grow faster by cutting our hair. This is what Ruiz assures in What your skin says about you. Neither the use of lacquers, gummies, hairpins or the dryer will make it fall more quickly than if we did not use them. They are some of the most widespread myths related to our hair that scientific evidence has been in charge of dismantling over the years. Then? What is the solution to avoid going bald? Is the transplant the only way out?

As the specialist explains, shampoos are not going to be of much use, but there are some treatments that offer good results for androgenetic alopecia such as minoxidil in the form of a lotion (a molecule that manages to improve capillary density), plasma infiltrations rich in platelets (PRP) or dutasteride and minoxidil. “The appearance of new antiandrogen drugs (finasteride and dutasteride) together with oral minoxidil and dutasteride or PRP injections, they have revolutionized the management of hormonal alopecia “, says the specialist.

“I can sunbathe with protector”

Sunburns are directly related to the possible development of melanoma. It is not something new. However, there are many people who still think that applying sunscreen gives you a kind of immunity against skin cancer. It is not true. “There are studies that show that applying a lot of sunscreen increases the risk of melanoma,” explains Dr. Ruiz.

“It should not be forgotten that some epidemiological studies have observed an increase in the incidence of melanoma among habitual users of sunscreen, which has been attributed in part to the fact that people who use more cream also increase the time of sun exposure by having the feeling that they are more protected than they really are. ” Thus, the dermatologist bets that creams with a factor less than 15 “disappear from the market”. On the contrary, it is advisable to always choose creams whose protection index is between 20 and 50. “A protection index of 30 blocks 96.7% while one of 50 blocks 98%”.
