1.What do you mean by scars? Scars are also called keloid scars, scarring. Scars have no skin texture, and no skin appendages such as hair, sweat glands, sebaceous glands, etc. Some are skin colored, some show hyperpigmentation or hypopigmentation, and fresh scars show red color. Scar is a skin symptom caused by physical, chemical or biological factors that lead to serious damage to the soft tissue of the skin, which exceeds its repair capacity and is repaired by collagen fiber replacement. 2.Are scars and spots the same thing? Scars are different from spots, the latter is just a change of skin color, such as vitiligo, coffee spots, post-inflammatory hyperpigmentation. Many patients tell their doctors that “I am scarred”, but it turns out that the doctor just looks at the pigmentation. 3.What types of scars are there? Scars can be divided into hyperplastic scars, atrophic scars and scars with pimples. (1) Superficial scars Most of them are caused by mild abrasions, shallow second-degree burns, superficial skin inflammation resulting in rough skin surface or pigmentation changes, local flatness and softness, and generally no functional impairment. The most common superficial scars are the depressed scars left by acne. Acne pits (2) Hyperplastic scars Scar tissue protrudes from the skin surface and often accumulates within the wound boundaries without infiltrating into the surrounding tissue. It is common in fresh scars, and usually flattens and softens gradually over 1-2 years, but there are also scars that have been shown to be hyperplastic scars. Hyperplastic scars (3) Atrophic scars are generally more severe injuries, involving the whole skin and subcutaneous fatty tissue. The clinical manifestation is that the scar is hard, flat or slightly above the skin surface, and closely adheres to deep tissues such as muscles, tendons and nerves. It is commonly seen in third-degree burns and chronic skin ulcers. Scar epidermis is thin and does not tolerate friction; scar contracture can pull the nearby tissues and organs, causing dysfunction. Atrophic scars (4) Scars, also called crab feet, are a kind of metaplastic growth of scars that protrude from the skin surface beyond the wound boundary, and even a little folliculitis can induce the growth of scars. Keloid scars 4. What should I do if I have a scar? No one has no scars on their body, and there is a story behind every scar. Scars may be a physical nuisance to you, but every scar allows us to grow spiritually. Most scars can be left alone or even forgotten about, but two types of scars cannot be left alone: scars that affect the appearance, but scars that affect the function. 5.Can scars be cured? Once a scar is formed, there is currently no way to make it disappear, but we can make it improve, or call it repair. If someone tells you that a scar can be completely removed, it must be a liar! You should not hesitate to turn your head away. 6.What are the treatment methods for scars? The treatment of scars can choose between surgical and non-surgical treatments. There are many methods of non-surgical treatment, such as compression therapy, closure therapy, cryotherapy, radiation therapy, hormone therapy, chemical peeling, laser therapy, etc. In recent years, fractional laser has achieved good results in treating superficial scars, and plasma beam treatment for scars is the latest research result. The doctor will make the most reasonable treatment plan according to the patient’s condition, which can be treated by surgery alone or a combination of surgery and non-surgical treatment.
