Scars beneath the skin are beautiful foes. However, injuries, surgeries, and acne can leave embarrassing scars on my body at any time, making me constantly vigilant. Therefore, during every vacation, those who hate ugliness aim their beautiful pursuits at these scars. Many of us believe that scar-repairing surgeries can quickly restore our beauty, just like how ice cream melts in summer to cool us down instantly. But the cooling effect of ice cream is only temporary, and soon you still feel hot and parched. Similarly, while scar-removal surgeries have evident beautifying effects, they also come with side effects.
### Scar Removal Surgery: Beauty Coexists with Regret
The impact of scars is not only physical but also psychological. Due to the "stubbornness" of scars, many people opt for cosmetic surgery, which, though effective, cannot be overlooked for its flaws.
#### Laser Therapy
**Principle:** By altering the focusing characteristics of the laser, a laser point becomes a spot. Using a graphics generator, the spot is scanned in a certain pattern, and the high heat generated by the laser removes the target tissue within the scanning range in an instant.
**Drawbacks:** It can only remove protruding skin and cannot level out depressed areas. Improper use of lasers may result in new scars or uneven pigmentation.
#### Collagen Injection
**Principle:** Highly refined bovine collagen mixed with an anesthetic is injected into the dermis layer so the body "fuses" with the collagen.
**Drawbacks:** Risk of allergy; an allergy test must be conducted before the procedure.
#### Fat Injection Method
**Principle:** Through surgical procedures, fat is harvested from another part of the body, washed clean, and then injected into the scar area to increase the fat content in the scar.
