Acne scarring is caused by fibrosis, which develops in the skin tissue after the acne lesions have healed. The skin created by the body at the location of the wounded region initially has a distinct look and performs different functions than the skin on the rest of the body. Nonetheless, as time passes, the body tends to replace it with skin that resembles the skin on the rest of the body. This is caused by the repigmentation procedure. Scars fade to varying degrees depending on a variety of circumstances, including scar size, kind, and depth, as well as other personal characteristics such as age and heredity, among others.

The following scar kinds exist:

• Keloids are rough, discoloured, and slightly uprooted scars that occur when your skin attempts to mend itself and creates too many cells.
• Icepick Scars: Have you ever punctured a potato with a fork? Icepick scars resemble the indentations made by a fork on a potato. Because acne depletes collagen, when the skin attempts to rebuild itself, it creates gaping holes.
• Rolling acne scars: If your skin has hills and valleys, you most likely have rolling acne scars. When you have rolling acne scars, the texture of your skin becomes wavy. These scars are the outcome of cyst acne-related long-term inflammatory acne.
• Boxcar scars are superficial scars that form as a result of inflammatory acne. Boxcar scars have sharper edges and create a deeper impression on the skin than rolling scars. It seems as if a fingernail has been purposefully pressed into your skin.
• Hyperpigmentation: Not a scar, hyperpigmentation is caused by your body producing too much melanin, leaving behind reddish markings. The skin’s surface reflects pigmentation, which is more melanin generated by your body.
