Acne is an inflammation of the pilosebaceous follicles of the skin of the face and sometimes also on the skin of the chest and back. The pilosebaceous follicles are formed by the roots of the hairs and sebaceous glands that secrete their contents to the outside through the channel where they exit hairs.


Why acne appear?

acne The hormonal changes of puberty also modify the skin: increase the sebaceous glands, which produce more fat that comes out, and easier to be "clog" the pores , forming blackheads, also called "pimples" or comedones, causing a buildup under the skin of all content that should go outside. This content is infected more easily produce inflammation, redness, and pus formation.


I have passed puberty, why I keep coming acne?

As we discussed before the hormonal changes that occur during puberty facilitate the appearance of acne. Over the years these changes are attenuated and tend to disappear beans. However, it is not surprising that people more often among women than among men, still met years (20, 30 and even 40 years) and still appear acne pimples.

They are generally not as numerous as in younger ages, but tend to be more persistent, slow to disappear between one and two months, more often located in lower areas of the face and sides of the neck and often coincide with the period premenstrual.

It seems that this fact fulfill years and continue consultation acne increasingly more assiduously. It is not well understood if they are actually increasing people with these circumstances or what happens is that the frequency is the same but people go more often to the dermatologist to try to eradicate. The cause is not known, but hormonal changes influence and a family history with persistent acne.

In addition, it is crucial for the appearance of acne in people predisposed to the use of cosmetics (moisturizing, cleansing milk, makeup, sunscreens) with fatty excipients that contribute to clog the pilosebaceous follicles, content retention and repeat the process we have explained above.


What kind of soaps help soften or remove it ?

Soaps as unique tool not usually sufficient to eliminate acne, but constitute a fundamental basis to complement treatments. The aim of cleansing the skin with acne is to remove excess fat and debris deposited on the skin.


Myths, truth or lie?

However, we must not forget that excessive sun exposure can cause side effects such as premature aging of the skin, staining and premature wrinkles and even the appearance of skin cancer; so it is considered advisable not use as treatment.

Moreover, it has less evidence of the efficacy of salt water as resolutive method. The per physical exercise also influences the evolution of acne, although people with this disease should be especially careful and take a shower with soap after appropriate physical activity to help eliminate all impurities on the skin.

When acne does not improve with hygienic measures explained by the dermatologist should be treated individually with different drugs depending on the extent, the predominant type of lesion (comedones, pus beans ...) and the appearance of scars. Remember that there are effective treatments for virtually all types of acne today.


sugar Does nervousness or anxiety can cause more acne appear?

People with acne often refer worsening his injuries during periods of stress. Dermatologists yet know the mechanism that justifies this association but probably related to hormonal changes that occur in these situations of nervousness and / or anxiety.


Does eating foods containing sugar favor increased acne?

The reality is that it is not scientifically proven this relationship. However, all balanced diets to avoid abuse of foods high in saturated fat and excess sugar contributes to overall health.
