Mechanism of acne scar formation

Acne scars are acne inflammation that damages the surrounding tissues and leaves pigmentation and scarring on the skin. Acne occurs repeatedly when the skin's immune system is compromised and the inflammation isAcne scars form due to damage to the dermis layer and subcutaneous tissue deep within the skinIt is caused by a variety of factors. Although it varies from one type to another, neglecting to take care of them is generally considered the main cause of acne scars.

■ Inflammatory response and collagen damage

Inflammatory response and collagen damage are deeply involved in the formation of acne scars. When acne occurs, the skin exhibits a self-defense response by becoming inflamed. In this process, collagen, which supports skin tissue, is damaged. The longer the inflammation lasts, the more damage is done to collagen, and as a result, acne scars are more likely to remain.

■Phenomena that occur during the skin repair process

Even though the acne appears to have healed on the surface, healing and repair continues inside the skin. During this recovery process, overproduction of melanin pigment may occur, resulting in hyperpigmentation. This occurs when the skin produces new tissue to repair the damage.Melanocytes are activated and produce more melanin pigment than normalThis is because it can cause Also, if the blood vessels remain dilated due to inflammation, redness may remain.

Types and characteristics of acne scars

Acne scars are characterized by different types. The main types of acne scars are erythema with redness, hyperpigmentation, crater-like indentations, keloids, and hypertrophic scars. In order to select the appropriate care and treatment, one must first understand the differences between them.

■Redness (erythema)

The most prominent of all acne scars is the redness, or erythema, which is the most visible of all acne scars. This is caused by a concentration of capillaries at the site of inflammation, resulting in a congested condition. The redness gradually fades with time, but if the inflammatory reaction is strongRemaining for more than a few monthsIt is not uncommon for patients to suffer from redness that does not disappear or heal for more than a year.

■Pigmentation

Pigmentation is a type of acne scarring caused by excessive production of melanin pigment during the healing and repair process of acne inflammation. It appears in shades of brown or reddish that are darker than the skin color,Symptoms persist for several months to several yearsThe degree and duration of hyperpigmentation may also vary depending on factors such as skin type, age, and sun exposure. The degree and duration of hyperpigmentation will vary depending on factors such as skin type, age, and sun exposure. However, in the case of severe hyperpigmentation, it is difficult to eliminate even if you try to manage it on your own. It is advisable to receive appropriate treatment at a clinic.

■Crater-like indentations

Crater-like acne scars, which look like depressed pore areas, occur when the intense inflammation caused by acne reaches the dermal layer and damages skin cells. The natural healing process does not repair the tissue normally, leaving a depression on the surface. The shape of the indentation varies and can be ice pick, boxcar, or rolling. This type of acne scar is difficult to heal spontaneously and tends to remain for a long period of time.

■Keloids and hypertrophic scars

Keloids and hypertrophic scars are particularly visible among acne scars. They are generally caused by abnormalities or delays in the healing process of acne. Both can also cause discomfort as well as visual problems, as they can be red and itchy. The development of keloids and hypertrophic scars can beGenetic factors and skin characteristics are involved.It is often seen in areas where the skin is easily stretched, such as the face line.

Factors that cause acne scars

Acne scars are caused by several complex factors. Here we will detail the three factors that induce acne scars.

■Excessive inflammation

One of the causes of acne scar formation is excessive inflammation. While normal acne will heal itself with proper care, prolonged and intense inflammation can damage the deeper layers of the skin and leave scars. Avoid forcibly crushing the pimple or touching it excessively, as this can aggravate the inflammatory response. To correct the condition, appropriate treatment should be sought.

■Inappropriate acne care

Improper acne care can leave scars. For example, irritating the pimples and excessive cleansing. This can worsen skin inflammation and increase the likelihood of scarring. How to properly care for acne,Be gentle and careful while maintaining cleanliness.is the key. Finding the right care method for your skin type, with the advice of a dermatologist or cosmetic dermatologist, will help prevent acne scars.
