acne scars
Introduction
Introduction Acne marks and acne scars are the pain of many acne patients forever. Although through a period of treatment, the acne on the face has healed, but because it is too late to seek medical treatment or the acne grows too much before, the place where the face has long acne left a lot of color shades of black Traces of black and red, serious and even scars of pits, reminiscent of orange peel or the surface of the moon, this is what we commonly call the so-called "acne scars."
Cause
Cause
Acne scars are caused by infection or external force, often because the acne attack does not receive timely and appropriate treatment, the inflammatory reaction of skin cells causes damage to the skin tissue, resulting in scars. Since the types of acne are various, there are many forms of acne scars, and the more severe the inflammatory reaction during acne attack, the more the skin tissue is destroyed, the deeper the inflamed part, the skin tissue is destroyed. The deeper, the more serious the acne scars that may be left in the future.

Acne scars can be divided into two types: pigmentation (ie, acne marks) and scars (depressions or bulges). The color spots are divided into red and black spots.
1, the red spot is because of the original acne, the cell inflammation caused by vasodilation. However, after the acne disappears, the blood vessels do not shrink immediately, and a temporary red erythema is formed. It will be redder when the skin temperature rises or moves. This erythema is not a scar and will gradually recede within 4 to 6 months.
2, while the black spot is caused by the pigmentation of acne after inflammation, leaving a dark and dirty color in the place where the red acne grows, making the skin dull, these black colors will slowly disappear on time. Those who are anxious have to apply some ointment that can be repellent or accept skin acid peel and vitamin C.
This type of pigmentation and pigmentation will disappear naturally over a long period of time, so it is usually a temporary pseudo-scarring, not a real scar. Of course, the disappearance of erythema and melanin precipitation takes a certain amount of time, otherwise the contracted blood vessels do not shrink, and the red color does not retreat; the pigment that is transported away by the cells is not transported away, and melanin cannot disappear.
In general, such false scars will disappear automatically on average about half a year, but some people will be longer than the average due to differences in personal physique, for example, one year or even two years. Can't wait for someone to help the external rubbing such as melanin ointment topical A acid, azalea, acid or levovitamin C, or accept fruit acid peel, dye laser, pulse light therapy, vitamin C import can accelerate color The spots disappear.
True scars are divided into pits and hypertrophic scars. Shinji does not disappear automatically and needs to be treated by a skin specialist to disappear.
1, pit scar is a more common situation, when the acne inflammation is too strong and the dermis collagen too much, it may be due to the collapse of the real skin leaving a cavity. Many acne patients like to squeeze acne by hand. If the squeezing is not appropriate, it will greatly increase the chance of purulent infection. It is easy to turn small acne, small acne into big acne, and then leave scars. Once the cavity is created, it will not disappear automatically. It is necessary to rely on laser dermabrasion to save.
2, hypertrophic scars commonly known as "crabs swollen", usually determined by the innate physique, the most difficult to treat, but also easy to relapse. This type of scar is exactly the opposite of a recessed scar. It is an overly hypertrophic scar. It leaves a distinct red protrusion in the place where it grows over acne. The appearance is red and swollen, and more seriously, it is because of sputum. Gradually grow up with the stimulation of external forces. It occurs in some patients with special constitutions. Because these patients have too active fibroblasts in the dermis of their skin, they overreact in the process of wound healing. As a result, the dermis is not recessed after being injured by inflammation. Raised to become hypertrophic skin tissue hyperplasia.

Hypertrophic scar: commonly known as "crab foot swelling", usually determined by the innate constitution, is the most difficult to treat, and easy to relapse. This type of scar is the opposite of a recessed scar. It is an overly hypertrophic scar. It leaves a distinct red protrusion in the place where it grows over acne. It looks red and swollen, and more seriously, it is because of sputum. Gradually grow up with the stimulation of external forces. It occurs in some patients with special constitutions. Because these patients have too active fibroblasts in the dermis of their skin, they overreact in the process of wound healing. As a result, the dermis is not recessed after being injured by inflammation. Raised to become hypertrophic skin tissue hyperplasia.
