Facial scarring is usually caused by scars that were left behind by an acne inflamation. There are two general classes of acne scars, defined by tissue response to inflammation:

(1) Scars caused by increased tissue formation, and

(2) Scars caused by loss of tissue.

Scars Caused by Increased Tissue Generation.

The proliferation of scars caused by increased tissue formation is called keloids. Keloid scars are associated to excessive levels of the cell substance, collagen. The overproduction of collagen is the body's response to injured skin cells. This extra production becomes piled up in fibrous accumulations, resulting in a characteristic firm, smooth, irregularly-shaped scars.

The typical keloid scar is 1 to 2 millimeters in diameter, but some may be 1 centimeter or larger. This abnormal growth of scar tissue is more likely to occur in susceptible people that is, people who are often related to others with similar types of scarring.

Keloid scars persist for years, but may decrease their size over time.

Scars Caused by Loss of Tissue

Acne scars associated with loss of tissue, similar to scars that result from chicken pox, are more common than keloids. Scars associated with loss of tissue are:

Ice-pick Scars or Pitted Scars

Commonly appear on the cheek. They are typically small, with visible jagged edges and steep side-like wounds that seem to form an "ice-picked" shape. Ice-pick scars may be shallow or deep, and may be hard or soft to the touch. Soft scars can be improved by stretching the skin; hard ice-pick scars cannot be stretched out.

Depressed fibrotic scars

Are commonly big in size, with sharp edges and steep sides. When touched, the base of these scars feels firm. Ice-pick scars may change into depressed fibrotic scars over time.

Soft scars

Superficial or deep and feel soft when touched. They have smoothly sloping rolled edges that combine with normal skin. They use to be small, and either circular or linear in shape.

Atrophic macules

Are commonly fairly small when they appear on the face, but may be a centimeter or larger on the body. They are soft, often with a slightly wrinkled base, and may be bluish in appearance because of the blood vessels located just under the scar. Over time, these scars fade from bluish to ivory white in color in white-skinned people, and become much less obvious.

Follicular macular atrophy

They are more likely to appear on the chest or back of a person with acne. These are tiny, white, soft lesions, often slightly raised above the surface of the skin somewhat like whiteheads that did not fully develop. This condition is sometimes also called "perifollicular elastolysis." The lesions may persist for months or even years.

Biological Ingredient Treats Acne Scars

Imbalanced tissue production can't be curbed with an everyday acne treatment product that was created for treating some acne breakouts. By using these products you will likely end-up with a drier skin texture that can present side-effects such as sun sensitivity, irritation or simply show no change at all. Your best bet is to use organic ingredients that bring collagen production back-up to normal and help 'disintegrate' and regenerate scarred tissue.

Most skin regenerative ingredients contain natural oils, but only one ingredient is capable of supplying a balanced mix of ingredients that trigger skin renovation. That miraculous component comes from a snail and is becoming the newest revolution in skin and scar treatment. Studies have shown that snail secretion contains a combination of naturally occurring allantoine, vitamins, glycolic acid, elastane and collagen, however, you have to keep in mind that complete scar renewal depends on the treatment itself and the extension of the scar.

So next time you look at your acne scar in a mirror and wonder why all the acne creams you've tried haven't changed a thing, try using an natural ingredient that can help regenerate scarred skin.
