Almost everyone has a scar that tells a story, but have you ever wondered why exactly scars form in the first place?
Pretty much everyone has some 除疤膏推薦 on their body that tells a story. But why does this weird tissue form in the first place? Well, scarring is, of course, part of our normal healing process. When you get a nasty scrape on your knee, for example, your body produces lots of the structural protein called collagen to help heal the injury. Collagen is found in connective tissue all over your body – it’s the stuff that keeps your skin firm, smooth, and stretchy.
And when your skin is damaged, excess collagen help fill in the wound with new tissue based on the size, shape, and type of injury. This new tissue has a different arrangement of collagen fibers than your normal skin tissue, and that is what makes a scar. But scars can take on different forms, depending on how the healing process takes place. The most common type of scars are probably hypertrophic scars.
In these scars, the buildup of collagen fibers from red, raised pattern on the skin. Over time, they can fade in color and smooth out, so you’re left with a less- visible patch of pale scar tissue. Sometimes wounds have an overgrowth of scar tissue and form keloid scars, which can be itchy, painful, and sometimes regrow even after surgical removal. Pitted, or atrophic, scars look just like they sound. They occur when fat or other tissue underneath the skin is lost in the initial injury, like after severe acen or chicken pox. So when skin heals over, a sunken pit remains. And contracture scars are frequently caused by burns – the wound shrinks as it heals, which causes twisted skin to form and restrict movement.
So there are lots of scars, but what can we do about them?
Some people say that lotions and creams – especially Vitamin E oil – will help reduce the appearance of scars.
But there’s not much scientific evidence to support this. However, there are some treatments out there. For example, corticosteroid injections can help clear up inflammation in hypertrophic and keloid scars, allowing the tissue to smooth out. Lazer therapy can zap the blood vessels in scar tissue to reduce redness and discoloration, and pitted scars can be smoothed out with injections of dermal fillers.
