scabs

Scales are a common symptom of skin infections and skin disorders of the immune system. Scales are also caused by the healing process, in which new skin grows over damaged skin. They may occur in conditions affecting one area of ​​the skin alone, or with more general conditions, such as shingles. Or chickenpox, or eczema only in rare cases, and crusts are found in a large area of ​​​​the skin.

Wounds from viral skin infections, including cold sores (herpes simplex), chickenpox (varicella-zoster), or shingles (herpes zoster) are common causes of dandruff, and blisters, cuts, abrasions, or burns may also cause crusts as they heal Depending on the cause, impetigo, a bacterial skin infection, can also cause scabs. The scabs may occur only immediately after an acute infection, or they may be the result of recurring episodes of a chronic condition such as psoriasis.

A rare autoimmune disorder known as pemphigus Vulgaris causes skin blisters and crusts and may be accompanied by blisters that may appear all over the body, including the scalp and inside the mouth. Scabs, including frequent scraping, rubbing or scratching.

Scaling is rarely a serious condition. However, any open wound can develop a serious bacterial infection.

How is the scab formed?

The wound goes through several stages until it heals, and the speed of wound healing depends on its size, as large and deep wounds need to heal for a longer period, and small wounds heal faster, and at this stage, the body’s immune system begins to protect it from infection after the crust is formed. skin damage

This is as follows:

• When you rub your knee or skin, a blood clot forms and eventually hardens into a protective crust. The scales form as a defense against infection and blood loss, which then regenerate tissue, pushing the crust out to make room for new skin to grow in its place.
• Although the new crust is sometimes unsightly, it is often a positive indication of healthy healing. However, recovery can take days to weeks to complete, depending on the severity of the wound.
• When the victim is exposed to wounds and others, the victim suffers from bleeding, and stop when the blood begins to clot for a few minutes or less, until the bleeding stops.
• The drying of blood clots stops and scales form, which contributes to protecting the internal tissues from microbes.
• The wound swells slightly, becomes red or pink, and becomes tender.
• Clear fluid comes out of the wound and varies by cleaning the affected area.
• The blood vessels in the affected area open to transport oxygen and nutrients to the wound through the blood.
• White blood cell resistance to microbes and wound healing.

Other than common scrapes or cuts, crusts can also form as a result of:

• Dry, cracked skin;
• Acne;
• bug bites;
• fungal infection;
• bacterial infection;
• Eczema;
• psoriasis;

Scales often heal on their own, but the healing process can sometimes take a long time if the wound is more severe. Here are some ways to speed up wound healing:

• Keeping the crust clean: It is important to keep the crust clean from exposure to infection, as dirt and germs can increase the risk of infection and slow the healing process, and the crust should be washed gently with soap and water while avoiding scrubs because it may scratch or irritate the crust, and can cause That in bleeding, repair and possible scarring of the epidermis.

• Keeping the wound area moist. According to the American Academy of Dermatology, keeping wounds moist helps heal the skin and speeds up the healing process. A dry wound scabs quickly and slow its healing ability. Moisturizing cuts or crusts can also prevent the wound from swelling and prevent Itching and scarring. Dermatologists also recommend applying petroleum jelly daily to keep the cut or scab moist.

• Take precautions: If you are physically active or if the scab is still fresh, cover it with a bandage to prevent further irritation and reduce the risk of scraping. Any excess trauma to the scab can slow healing and cause bleeding or swelling. Scales are a normal part of healing but are It can be unsightly if the wound area is large, while it can go away on its own, and home remedies can help speed healing.

The stage of scab formation

At this stage, the body's immune system begins to protect the body from infection after the formation of the bark, as follows:

• The wound swells slightly, becomes red or pink, and becomes tender.
• A clear liquid comes out of the wound, and it cleans the affected area.
• Opening the blood vessels in the affected area to transport oxygen and nutrients to the wound through the blood.
• White blood cell resistance to microbes and wound healing.

When does the scab fall off?

The crust may remain there for a few weeks and will gradually regress with normal activity. Small pieces of the crust may remain while others fall off. Your incision may heal more quickly in some areas than others, especially if it is in an area where movement may put extra pressure on the skin. Small parts of the incision.
