The most effective treatment for acne scars by far is dermabrasion. In this treatment, a high speed brush called a fraise is used to remove the skin on the surface and to clear the way the scars are formed. This treatment is done under local anesthetic. While the superficial scars are completely removed, the deep seated ones are reduced in their depth. But dermabrasion also has certain strings attached to it. They can make the ice-pick scars more noticeable. Apart from that, dark skinned people need to undergo further treatment after dermabrasion to clear the alteration of pigmentation that it causes.
Another advanced form of dermabrasion is microdermabrasion, which is a relatively new technique in which, instead of high speed brush, aluminum oxide crystals are used. These crystals are passed through a vacuum tube and remove the skin surface. The good thing about microdermabrasion is that it removes the surface skin in a way that no additional wound is inflicted. But the negative point is that even after a few sitting in the treatment, the scars do no not disappear permanently.
Thus, even after the introduction of microdermabrasion, dermabrasion is more preferred as the results are better, disregarding the collateral damage.

On one side we read that excess tissue formation leads to scarring, but a loss of tissue may also lead to various kinds if scars. These scars are like the scars that are left after small and chicken pox. They are very common, in fact more common that the keloids.

Ice-pick scars are the small jagged and steep scar that we usually locate on people’s cheek. They can be treated by stretching the skin. They are hard and soft both. But the hard ice-pick scars are difficult to stretch out.

There is another type of scar which is very big, sharp edged and with steep sides. This scar is firm to touch near the base. Sometime, the ice-pick scars take this form over time. This type of scar is called a depressed fibrotic scar.

There are some scars that are soft to touch and may be deep seated or superficial. These are called soft scars. These are characterized by sloping, rolling edges, mingling with the normal skin. They are small, linear or dome shaped.

Many people have big scars in their back and upper arms and the buttocks. These scars are the big atrophic macules, which are much smaller on the face. They are bluish in color as the veins lie just below it. They turn white overtime and become negligible in fair skinned people, but shows even then in dark skinned people.

It has been proven scientifically and observed generally that about 100% of people in the age group of ten to eighteen have at least some bouts of acne, in the form of comedones (blackheads or whiteheads) or pimples or in some cases, and mostly boys, nodules. It does not depend which race or ethnicity one comes from, acne can be called a universal phenomena in adolescent human beings. It is most rampant in that age group because of changes in the hormones. This hormonal imbalance or general change due to reproductive maturity causes those ugly lesions. Hormone levels are generally high and active. Thus this excites the oil or sebaceous glands, which then, along with the sebum, dead skin cells and tiny hairlets forms an acne lesion.

Ten to thirteen years is the most commonly observed age group where acne starts appearing. It lasts up to a maximum of ten years, which is marked by ne peak year which is the most affected stage. Nodular or cystic acne appear at this time. This may take a while to heal, unlike the other less severe forms. Teenagers become insecure and short-tempered due to the facial unpleasantness mainly. Sometimes these adolescent acne can continue up to adulthood also.
