What is acne?

Although surely you already know or even have suffered from this disease, we will talk a little about the causes that produce it and its general characteristics, so we can expand our knowledge and clarify doubts about this pathology so common in the general population.

In this sense, acne is a skin disorder that has its origin in the hair follicles. During this disease, these follicles become clogged with fat and dead skin cells. As a result, comedones, blackheads and grains can form.

Acne can appear on different parts of the body, but the most common areas are the face, back, chest and shoulders.

Four main causes have been established, which are:

  1. A bacterial infection, such as that produced by Propionibacterium acnes.
  2. Excessive fat production.
  3. An obstruction of the hair follicles by accumulation of fat and dead skin cells, as we had already mentioned.
  4. High hormonal activity, especially of androgens.

In addition to this, there are other factors that favor the onset of this disease and that aggravate it. For example, stress can make this condition worse, as well as diet and certain medications.

Tretinoin benefits

Tretinoin is, as we have seen, a retinoid. Retinoids are involved in numerous organism processes, such as cell differentiation and proliferation, as well as in apoptosis, or programmed cell death, and reproduction.

This medicine stimulates mitosis of skin cells and reduces intercellular cohesion of the stratum corneum. In addition, it interferes with the abnormal keratinization of the hair follicle, thus preventing excess keratin from forming and lipids accumulating. Keratin is a protein with a very fibrous structure that constitutes the main component of the outermost layers of the epidermis.

In addition, tretinoin has a comedolytic action, that is, it manages to normalize the desquamation of the follicular epithelium and thus reduce the obstruction of the follicle. It also has an anti-inflammatory and preventive action for the formation of new microcomedones, which we know as pimples.

Warnings

It is important to take into account a series of precautions when you are using this retinoid. In this regard, avoid:

  • Sunburn.
  • Photosensitivity reactions.
  • Avoid contact of the product with the eyes, eyelids, nose, mouth and other mucous membranes of the body.
  • Elderly people have to take special care, as do children, since a safety profile has not been established in people with younger ages.
  • Avoid infections in the affected areas.
  • No pregnant woman should take oral retinoids, such as tretinoin, during pregnancy. Nor should any woman who can become pregnant during treatment take them. Topically, the risk is not so high, but it should also be avoided.
