When that pesky pimple penetrates deeply into your skin, it can damage the skin and the tissue beneath it. And as the acne clears, the body tries to repair the damage caused.
During the healing process, the body produces collagen. If the body produces too little or too much collagen, you will see a scar. Moreover, the type of scar depends on how much collagen your body makes.
Depressed acne scars are a result of too little collagen being produced in the body while Raised acne scars are caused when the body produces too much collagen.
There are many treatment options when it comes to aesthetic, which can significantly diminish depressed and raised acne scars.
