Wrinkles Heal From Within: Six Things You Didn’t Know About Skin

It is the largest organ in our body, covering everything else in one piece, but we do not tend to think of the skin as an organ in itself. We also do not have in mind that it is impossible to speak of a single skin: it is made up of mmcthai several overlapping layers to protect us even more if possible.

Now that summers and its harsh sun linger over fall and spring, it’s more important than ever to learn about your skin to make sure we maintain its health and beauty.

Skin figures

The skin is the largest organ in the human body, above the liver or intestines, representing 15% of a person’s body weight (an average of 4 kilograms).

The outer layer of the skin measures approximately 2 square meters, which are replaced every 20-30 days. In total, throughout life, the skin sheds a thousand times. On the other hand, every day between 20 and 100 hairs are lost on average. 50% of the ‘dust’ in a home tends to be skin and hair that falls out during the day.

As for the thickness of the skin, the thinnest skin is on the eyelids of the eyes, while the thickest skin is on the soles of the feet.

Skin diseases

Among the most notable skin diseases are acne, in which 1 in 20 women suffer from 1 in 100 men.

For its part, among other common skin diseases, are seborrheic dermatitis -characterized by an excess of fat in the hair that is released in the form of scales-, atopic dermatitis -a skin inflammation that is usually associated with asthma- and psoriasis – characterized by inflammation, peeling and itching.

Finally, standing out as a rare disease, albinism, or lack of skin pigmentation due to a genetic disorder is suffered by 1 in 110,000 people. This disorder involves having extraordinarily white skin, including a lack of color in the eyes and hair.

Effects of the sun on skin and hair

There is a paradoxical effect of the sun on the skin and hair: the skin usually darkens, while the hair usually lightens.

This is because the hair is made up of dead cells, so they do not renew their melanin as quickly as it does with the skin, and it is only renewed when new hair grows. However, in the skin, the lack of melanin could have terrible consequences, since the cells are alive, and they constantly renew this pigment. Said melanin is distributed through the layers of the skin, and its production increases against the sun to protect it better.

However, over the years, skin cancers usually affect the scalp area greatly because they have not used protective cream in that area, or caps or hats, or any other type of protection. Therefore, even though the hair cannot suffer the sun’s effects like the skin, it is convenient to remember that there is skin to protect under the hair.

Skin cancer

The individuals most likely to suffer this type of cancer are those with paler skin since they have less melanin. This does not mean that dark-skinned individuals are, however, totally safe. It is also known that skin cancer also has a certain genetic component, so having a family precedent is a factor to consider to carry out an early diagnosis.

Likewise, it is known that sunburns suffered during childhood can generate cancer in adulthood, although a large part of these cancers is discovered after the age of 50 due to their slow progression.

Finally, there is a type of skin cancer called uveal melanoma, the most common type of cancer in the human eye, making it extremely important to protect yourself with appropriate sunglasses.

Collagen to maintain its firmness

The skin shows the most visible signs of aging in humans: it becomes dry, discolored, and loses its firmness, giving way to wrinkles. Collagen is responsible for this, abundant in youth and fundamental for the consistency of bones, muscles, and skin, but whose reserves disappear after thirty. The body, likewise, replaces it more and more inefficiently.

Anti-wrinkle creams act on the superficial layers of the skin but do not reach the deep layers in which collagen acts. Orally ingested tablets have shown some effect according to studies, but have the problem of breaking down in the digestive system before it does its job. Dermatology has used lasers, radio frequencies, and injections to stimulate collagen production.

However, dermatologists say that the best thing we can do with collagen is to preserve what we have. The same tips that prevent skin aging are used for this: protect it from the sun, avoid smoking, get enough sleep, have a diet rich in fruits, vegetables, and fish, and take measures against the wear and tear caused by physical exercise. In any case, the aging of our skin is also determined by genetic factors against which little can be done.

The skin of the future

When large skin injuries occur, especially from burns, human skin grafts are usually performed from donors or, depending on the amount of skin needed, even from the same individual who suffers the injury.

This technology is capable of creating the layers of the skin, but its secondary structures are still under study and process.
