It is a potential barrier against unwanted entry of irritants and microorganisms into the body. It ensures the maintenance of proper balance between the body and the environment. The protective function is provided by the stratum corneum, which is the outer part of the epidermis. It consists mainly of keratin - a highly resistant protein.
In addition, the large presence of water and fat in this layer provides it with adequate elasticity and resistance to mechanical stimuli. As a result of constant keratinization of the epidermis, and thus exfoliation of the horny layer, it is possible to remove harmful substances from the skin surface. Lipid protection is also important, i.e. the sebum layer which is a mixture of sebum secreted from the sebaceous glands and lipids derived from epidermal cells. It is an essential part of the skin lubricating and forming a protective layer on the skin protecting it from external factors such as bacteria, viruses, fungi and UV radiation. In addition, the skin provides protection against physical stimuli such as UV radiation, hot and cold stimuli.
Abrasions are one of the most common epidermal injuries. They are usually caused by moving the skin against a hard or rough surface. They represent a shallow wound affecting the top layer of the skin. They heal without leaving a scar. It is important that even such small wounds as abrasions are properly dressed and protected against unwanted infection.
To properly clean an epidermal abrasion, wash it thoroughly with soap and water, hydrogen peroxide, or a disinfectant spray. Do not use gauze or cotton balls for this purpose, as saprophytes may be transferred to the wound feeding on dead organic matter. For adequate protection of the resulting abrasion, it is worth using ointment acting antibacterially, shielding and accelerating the healing process. Even a small abrasion is the gateway to the penetration of bacteria into the body which can lead to the appearance of infections.
It is important to properly protect the resulting abrasion before contact with external factors when leaving the house. If the dressing is dirty or wet, remember to replace it as soon as possible. If, despite following the above methods, the abrasion is not healed it is necessary to consult a doctor.
The use of appropriate preventive measures can effectively protect us from the occurrence of abrasions on the skin. The places most susceptible to the appearance of the wound should be properly protected with ointment (such as Vaseline, Lubricant nt in spray) to properly lubricate the skin. Also, remember to moisturize your skin, as a properly moisturized body is less prone to the appearance of abrasions.
Consume adequate amounts of water to reduce the amount of salt in sweat found on the skin. Take care to use preventive measures so as not to lead to the appearance of abrasions, and if it does occur, remember to properly clean and protect the wound. Applying the above rules will avoid the risk of infection at the site of injury.
