Pocket scars can be mainly divided into spots (that is, acne marks) and scars (depressions or bulges). Among them, spots are divided into red and black.
Erythema is caused by inflammation of cells in the original acne area, which leads to vasodilation. However, after the acne disappears, the blood vessels will not contract immediately, forming a temporary erythema with a flat red color. Skin will be redder when the temperature rises or when you exercise. This erythema is not a scar, and it will gradually fade in 4 to 6 months.
Black spots are pigmentation after acne inflammation, which leaves a dark and dirty color in places longer than red acne, making the skin dull. In fact, these blacks will gradually disappear over time, so impatient people have to apply some ointment that can remove melanin or accept fruit acid rejuvenation and vitamin C introduction.
This stain and pigmentation will disappear naturally after a long time, so it is generally a temporary fake scar, not a real scar. Of course, erythema and melanin precipitation will take some time to disappear, otherwise the contracted blood vessels will not contract, and the redness will not retreat; Melanin can't disappear unless the pigment that should have been transported away by cells is transported away.
Generally speaking, this kind of false scar will disappear automatically in about half a year on average, but some people will take longer than the average time because of their different physical fitness, such as one year or even two years. People who can't wait can only apply A- acid, azalea acid, fruit acid or L- vitamin C for external use, or accept fruit acid rejuvenation, dye laser, pulse phototherapy and vitamin C introduction to accelerate the disappearance of spots.
True scars are divided into concave holes and hypertrophic scars. Real scars don't disappear automatically, only after treatment by dermatologists.
Pits and scars are common. When the acne inflammation is too strong and there is too much collagen in the dermis, it may leave a pit because of the collapse of the dermis. Many acne patients like to squeeze acne by hand. If they are squeezed improperly, it will greatly increase the chance of suppurative infection, and it is easy to turn small acne and small acne into big acne, thus leaving scars. Once the pit is created, it will not disappear automatically. You have to save it by laser dermabrasion.
Hypertrophic scar, commonly known as "crab's foot swelling", is usually determined by congenital constitution, which is the most difficult to treat and easy to recur. This kind of scar is just the opposite of concave scar. This is a very thick scar. In the place where the acne has grown, there are obvious red protrusions, and the appearance is red and swollen. What's more, it will grow up slowly because of scratching or external stimulation. It often happens to patients with special physique. Because the fibroblasts in the dermis of these patients are too active, they overreact during wound healing. As a result, the dermis is not depressed, but raised after being damaged by inflammation, and becomes hypertrophic skin tissue hyperplasia.
The problem of acne scar covers the epidermis, dermis and subcutaneous tissue of the skin, and the consequences include skin damage, tissue defect and scar formation, which not only causes skin appearance defects, but also affects the normal tissue structure of the skin. In order to improve the problem of acne marks and scars, it is necessary for doctors to diagnose and evaluate different types of scars to determine the treatment plan.
Treatment of black acne scar;
A) Use L-C skin care products or L-C ultrasound to introduce: brighten skin tone and promote skin collagen production.
B) Use skin care products containing fruit acid: simultaneously treat acne and improve acne scars, promote the exfoliation of old and waste keratin, help skin renew, improve pigmentation after acne and fade dark spots.
C) Efficient natural herbal whitening products or whitening courses: slow down the production of deep melanin and accelerate melanin metabolism.
Treatment of red acne scar;
A) Pulsed light: It can contract microvessels and lighten scars, but it needs multiple treatments. Pulsed light can also increase the collagen in the dermis, make the depression no longer obvious and enlarge the pores, so it is also suitable for skin with erythema and slight pits.
B) Use skin care products containing fruit acid: simultaneously treat acne and improve acne scars, promote the exfoliation of old and waste keratin, help skin renew and improve pigmentation after acne.
C) Purification treatment: anti-acne, pore removal prevention and intensified anti-acne treatment.
Treatment of concave scar;
A) Fruit acid rejuvenation: high concentration fruit acid is used to remove the aged stratum corneum, accelerate the renewal of keratinocytes and a small amount of epithelial cells, and promote the proliferation of elastic fibers in the dermis. It has a good curative effect on superficial acne scars and can also improve the coarseness of pores, but it takes many courses to eliminate, but its advantages are safety and few side effects;
B) Filling method: implant (such as collagen) is injected to make the concave part bulge and flush with the surrounding skin tissue;
C) Pulsed light: Stimulate the proliferation of fibroblasts, thicken the dermis and flatten the pits. At the same time, because pulsed light can stimulate the proliferation of collagen, this method has certain effect on red acne marks and newly generated shallow pits.
D) deep skin regeneration treatment: for deep acne, remove pores, dilute acne scars and brighten skin tone;
E) Laser dermabrasion: It is suitable for deep pits, and can be performed according to the depth of pits in the skin. It only takes 2~3 times to get good results, and the effect is lasting. However, due to the trauma of laser dermabrasion, it is necessary to cooperate with postoperative maintenance. If the postoperative care is not good, the skin may turn red and black.
Treatment of hypertrophic scar;
A) Local subcutaneous injection: For swollen crab feet and hypertrophic scars, drug injection is directly injected under the skin of acne scars for treatment. This drug is mainly composed of steroids, which has the functions of anti-inflammation and dissolving inflamed tissues. This is the simplest and most effective treatment for hypertrophic scar at present. After several injections, the acne scar can gradually soften, from convex to flat, but the pigmentation of scar tissue can not fade, so there will still be some traces after healing, which can not completely restore the appearance of normal skin.
B) Phototherapy, such as laser, such as dye laser, can smooth hyperplastic scars.
