Hypertrophic Scar

An acne scar can be deep or shallow, small or large, and dark or light in appearance. Even the best acne treatment in town cannot stop an acne scar from its development because the original structure has been compromised by the skin infection. The good news is that there are many effective ways to significantly lessen the appearance of an acne scar such that it becomes invisible to the naked eye.

But not all acne scars are carved equal on the skin, pun not intended. Don't expect an atrophic scar to heal in the same manner and be treated with similar approaches as a hypertrophic scar simply because these are two different types. While an atrophic scar is caused by the loss of tissue, a hypertrophic scar is caused by excess tissue.

Within these two general types of acne scarring are four sub-types. Keep in
The result is a deep, narrow hole in the skin that may also look like a large and open pore. This type of acne scarring develops after a cyst infection works its way toward the skin's surface. When the skin heals, a column-like scar remains.

Effective treatment for an ice-pick scar can be either punch excision or punch grafting. Both involve excising the scar with a punch tool and then either suturing shut the skin edges (punch excision) or filling in the skin defect with a graft (punch grafting). Resurfacing techniques will then make the scar less noticeable.

Boxcar Scars
A boxcar acne scar results from the destruction of collagen due to an inflammatory breakout. It appears like a round or oval depression coupled with steep vertical sides. Think of skin with the pitted appearance of an orange, albeit with wider diameters on the holes. Similar to the ice-pick type, a boxcar scar responds well to punch excision. Other options include laser resurfacing and dermal fillers, although results will vary depending on the severity of the scarring
