When the body is injured, according to the degree of damage in the wound or wound, the surrounding skin tissue will also be damaged to varying degrees. The tissue liquid seeps out. After a period of time, fibrin condenses, after a period of time, with the dryness of the wound and exudate liquid coagulation, it is dark red, which plays a role in protecting the wound. Skin tissue under crusting can grow and repair in a relatively closed and clean environment.

Why do you feel itchy when you scab?

Can't help but always want to deduct?

As the scabs of the wound improve, we will feel itching of wounds and surrounding skin. This is because the skin tissue and granulation tissue in the scabs are growing and repairing. It shrinks to the wound, so it feels itchy, and I can't help but always want to deduct. This is the normal situation of wound healing.

When the wound is itchy, remember not to scratch, nor can you unveil the scabs. After the crust is buckled, it will bring pollution concurrency and infection around the wound and wound, which will affect the protection effect of crusts on wounds. After falling off, the wound will not itch anymore.

Can the wound take a bath after scabbing?

1. superficial wound/larger wound

If it is a superficial wound, it is recommended to protect the wound;

If it is other large wounds, you can only wipe the surrounding skin, and you can't water.

Second, the scabbing wound

When taking a bath, you must protect the wound or wound, so that the crust cannot be shed, let alone the wound or wound under the crust.

(1) Blood scab covers the wound/wound is in the period of recovery

If you go to take a bath at this time, the blood scab will be soaked in warm water for a long time, causing the blood scab to soften, which will pollute the wound, which will cause bacteria to breed secondary infections;

If the blood scabs fall off due to the bath, the wound that has not been healed will be exposed, and it will be more likely to cause infection.

Therefore, at this time, try not to take a bath or do some housework and work soaking in water.

(2) Wound crust has been complete/wound has healed to the middle and late stages

Gently rinse when bathing does not have any impact on the healing of the wound.

However, after taking a bath, you need to do some simple treatment of wet wounds and crusts, disinfect with alcohol and iodine appropriately, and cover with gauze. Heal recovery.

Does it have any effects?

After the wound or wound healing, the blood scabs will fall off by themselves. Early deducting crusts may cause bleeding. Because the subcutaneous tissue has not fully recovered, it is likely that scar hyperplasia or pigmentation will occur.

After the small wound crusts, if it is relatively lighter, the wound does not hurt the deep subcutaneous tissue. Generally, it can fall off by itself in a week or 10 days without leaving scars. The shorter the wound healing time, the less likely to heal the wound that can heal in less than a week, the chance of generating scars will be very small;

If the wound is relatively or deeper, it is damaged to a certain depth, such as damage the subcutaneous tissue to the leather or deeper level, especially the wound healing time for more than two weeks or even more, then the probability of scars on the wound is very very likely big.

How to avoid wound scars?

Correct treatment of wounds

1. Actively prevent wound infection

Because the secondary infection wound is a very important factor for forming a scar. After the secondary infection of the wound, the healing process will be prolonged. The wound after healing usually leaves pigmentation. ; A relatively clean wound, healing time will be faster, and the possibility of leaving scars will be very small, so it is very important to protect the wound to avoid infection.

Wipe and disinfect with medical iodine or alcohol, and then simply bandage; Sewing, such as iodophor, alcohol, hydrogen peroxide, etc., the surface of the wound and deep pollutants and cleaning some damaged tissues of physiological saline, etc., necessary sutures, bandaging, changing drugs on time, etc., you need to closely observe whether the wound is infected with infection Essence

2. Protect the wound

Avoid the second bumps and other injuries to the wound, not too much activity, especially on the wounds of joints such as fingers, elbows, knees, and ankles, otherwise the wound will be excessively pulled and stimulated, which may cause the wound to heal in healing During the process, hyperplasia scars are formed.

Crusting of scars

1. Do not pick up the scabs prematurely

Especially when it feels itchy, the formation of crusts should be fell off by themselves, so that the skin should be repaired on the surface under the protection of scabs.2. Use some products that promote skin tissue repair for prevention

Therefore, the formation of scars is reduced. For example, the commonly used frozen dried powder containing PB yeast polypeptide ingredients has a certain effect on skin tissue, as well as drugs such as silicone gel, chrysanthemidin cream, growth factor gels and other drugsPreventive treatment scars.

3. Special circumstances
