How to get rid of this scar?

Drop ~ Your pet powder Xiaoming has been online ~

Before, a fan left a message asking if he could have a scar removal of scars. When he saw the praise, he knew everyone's obsession. Although Xiaoming arrived late!

Everyone's body is more or less scarred. Xiaoming heard a romantic saying: Scar is a medal left after the skin battle.

See how high emotional quotient words, you still bear the scar when you see this?

Can't bear, go to get out of class!

Scar formation

To get rid of scars, you must first know how the scar came.

Our skin is divided into epidermal layers, dermal layers and subcutaneous tissues.

If you just hurt the epidermis layer, it is usually just peeling or abrasion, and generally will not leave scars; if you hurt the dermis layer and below, the wound will bleed and leave scars, which can be roughly divided into 4 stages:

1. Anti -bleeding period: After the skin injury, the first one to play is the coagulation system. It "work" is very efficient. After a while, the wound will not bleed;

2. Inflammation period: When the coagulation system is completed, it is the immune system to play. At this time, the immune cells are busy eliminating the necrotic cells and bacteria. The wounds may appear red, swollen, heat, and pain. Usually it ends within 3 days.

3. Proliferation period: including epithelial formation and fiber hyperplasia. Epithelial cells are responsible for growing and mature from the edge of the wound to the center to form complete skin. Fiber cells are responsible for gathered in large quantities at the wound, producing new collagen fibers to fill the damaged area.

4. Mature period: At this time, the epidermis and leather have completely healed, and finally leave the incompatible scars.

According to different anatomical forms, scars can be divided into proliferative scars, scarring, atrophic scars and scar cancers. Among them are more commonly proliferated scars and scarring.

● Proliferative scars are mainly produced in trauma, surgery, trauma, burns and so on. Generally speaking, where is injured, the hyperplasia scar will grow, and it will not exceed the edge of the original trauma surface.

● AEx is a pathological healing of surgery, burns, soming, pierced ears, tattoos, and vaccines. It will "rampant" to the neighboring area, exceed the area that was originally damaged, and invades the surrounding healthy skin.

After understanding the origin and classification of the scar, how can I get rid of the scar?

(Mainly refers to proliferative scars and scarring. As for acne scars that everyone cares about, you can see this → acne "sequelae" -the acne marks and acne pits can be tidy?!)

Is scar removal ointment useful?

When it comes to scar removal, the first thing you think of is the scar removal ointment. After all, everyone has the highest acceptance of external medicine. But is it really useful for scar removal ointment?

Studies have shown that in the early stage of scars, products containing silicone ingredients (silicone ointment, cedar cream, silicon film, etc.) have a certain improvement effect on scars.

In other words, it is useful, but the effect is limited!

And the early use of scars is needed. If it is an old scar, the effect ... you know.

In addition to silicone ingredient products, stress therapy (elastic jacket, bandage) is also one of the early effective treatment for scars. Its mechanism may involve the reduction of oxygen -dividing pressure through the small blood vessels inside the closed surface, thereby reducing the proliferation of fibroblasts and collagen synthesis.

More effective method of scar removal

At present, the best way to remove scar removal is still the medical beauty.

Laser Treatment

Usually divided into two categories, one is aimed at capillary blood vessels, mainly a capillaries that are expanded or proliferated in closed or solidified scars, thereby blocking the nutritional blood supply of scars, such as pulse dye laser, long pulse ND: yag laser (1064nm), etc.

There is also a category to promote the degradation of fibrous cell apoptosis or type I collagen (a collagen that exists in the scar tissue), such as carbon dioxide dot matrix laser.

Local injection

Injecting therapy is usually used for scars scattered, isolated, no secondary infection and ulceration.

Injecting corticosteroids in the scar (Qu Anned) can not only inhibit fibroblast proliferation, thereby softening peaceful and compound scars, but also anti -inflammatory and blood vessels, effectively reducing pain and itching. Studies have shown that the efficiency of corticosteroids is 50%-100%.

If corticosteroids are invalid, you can also choose to inject fluoropromoline (FU), which can induce the apoptosis of fibroblasts without necrosis, and can inhibit the production of type I collagen.

Studies have shown that the effect of FU and Qu Annend's injection treatment is better than a single bet.

Local injection is a relatively high cost -effective treatment method. However, it should be noted that the injection can soften the scar and make the scar flat, but it is easy to recur. And multiple injection can also cause local skin to depressed, so once the scar is close to the surrounding skin height, the injection treatment needs to be stopped.

operation treatment

If the above treatment effect is not satisfactory, and you want to remove scars very much, you need to consider surgical treatment, including surgical resection, scarring leather transplantation, and scarring core resection.

● Surgical resection is suitable for scars that are not very large and relatively single, but the recurrence rate after surgical resection is high. It is recommended to combine shallow X -ray radiation therapy after surgery, or to assist laser treatment or injection treatment after the line disassembly is removed, so as to use it to treat or injection treatment. Reduce the chance of recurrence after surgery. This is currently a relatively mainstream surgical treatment.

● Scar leather reflection is a way to cut the scar, then cover the skin of the scar, and combined with the treatment of shallow X -ray radiation therapy. ● The kelp albulfate is mainly used for hypertrophic scars that are not obvious in laser effect. First, the kernel of the scar is removed to thin the thickness of the scar, and then the laser treatment is combined.

Xiao Ming told everyone that in order to remove scars, combined treatment is more effective than single treatment. Doctors usually treat joint treatment according to the size, type and growth site of the scar.
