There are instances when an acne breakout damages the skin deeply and severely, in that it not only affects the upper layers of the skin, but also the tissues beneath it. In response, the body produces collagen, which is a protein that is an important component of skin regeneration.
This is a critical process, because where there is very little or excess collagen formation, a scar can eventually form. What is more concerning is that acne scars become more noticeable as a person ages because of the decline in collagen levels.
To effectively treat acne scars, it is important to determine what type they are.
