Types Of Acne Scars 

Scarring is the skin's response to injury. Acne scars occur when spots become inflamed or do not heal properly. Up to 30% of those with moderate to severe acne will scar. Some individuals are more prone to scarring than others, due to skin color or hereditary factors.

Picking at spots increases the chance of scarring as it can cause the lesions to become infected. To reduce the chance of scarring, treat your acne early.

Color changes:

Inflammatory acne lesions that have recently healed may leave behind flat reddish spots, darker brown marks (pigmentation) or white marks (hypopigmentation). These colored spots may remain for several months but will eventually disappear, hence are not true acne scars. However, they are visible and may cause embarrassment.

Persistent scarring:

Scars that occur from the more severe acne lesions may improve with time but usually never disappear. These can be categorized as follows:

• Ice pick scars - These are pitted scars – they leave pits or crater-like impressions in the skin. They are more common in lighter skinned individuals. 
• Atrophic scars - These are flat, thin scar and may be slightly raised. 
• Hypertrophic Scars -  Also known as keloid scars, these are thick lumpy and more common in black and Asian skins. Keloid scars tend to run in families. They persist for years but may get smaller over time. 

Acne Scars treatment can be effective if the correct medication is applied for the type of skin scarring. There are treatments for common type of scars.
