It can be seen that there is a red lump with hard texture, smooth surface, itching and pain, and keloids can also expand outward like crab feet. Rich blood supply, oxygen free radicals more than 2 times higher than normal skin, and active fibroblasts in raised scars.

(such as erythema, white spots or pigmentation of the skin), generally no dysfunction, but this kind of scar greatly affects the visual beauty.
4. Spontaneous keloid
Spontaneous keloid has no obvious inducement. It occurs on normal skin or is not caused by slight abrasion, so that the skin induration gradually grows, and the edge is irregular and spreads to the surrounding area, forming crab feet or centipede-shaped, butterfly-shaped, round, hard, reddish or dark red, consciously itching, sometimes accompanied by paroxysmal pain or tingling.

Such as: freezing, laser, mole removal, eyebrow washing, ear piercing, vaccination, skin grafting, caesarean section and other scar hyperplasia. , red or dark red, itching, tingling higher than the skin, eating spicy food, wine and other irritating foods aggravate the symptoms.
Precautions before scar surgery:
1. A comprehensive physical examination should be conducted before scar repair surgery to ensure good health and no infectious diseases or other body inflammation.

Matters needing attention after scar surgery:
1. Don't touch the surgical site with water until the scar is removed and the incision is not healed. Scar repair surgery ensures that the surgical site is clean. All these require patients to develop good hygiene habits, and pay more attention to this aspect at ordinary times.
2. Within 3 to 6 months after operation, it is best to reduce the intake of spicy food such as tobacco and alcohol. Because these foods will stimulate the vascular response, make the surgical site congested, accelerate the recurrence of scars, and thus lead to scar recurrence.
Direct sunlight should be avoided. Long-term exposure to the sun will deepen the scar color.
4. It is forbidden to do strenuous exercise before the wound heals to prevent the wound from cracking.
5. According to the doctor's advice after operation, start scar treatment as soon as possible, such as shallow radiotherapy, elastic compression therapy, scar patch, local sealing and botulinum toxin treatment.
It is the first step to say goodbye to scar bravely to face scar surgery correctly and accept scientific, safe and guaranteed surgical treatment. In addition, we should follow the precautions before and after scar surgery to ensure the safety of surgery and good recovery after surgery, so as to achieve the best surgical effect.
