Lesions or scars left on facial skin, chest or back are usually caused by acne inflamation that has come and gone. There are two main classes of acne scars, defined by tissue reaction to inflammation:

(1) Scars caused by increased tissue formation, and

(2) Scars caused by loss of tissue.

Scars Generated by Exaggerated Tissue Generation.

The generation of scars caused by increased tissue formation is called keloids. Keloid scars are linked to disproportioned levels of the cell substance, collagen. The overproduction of collagen is the body's reaction to damaged skin cells. This excess becomes piled up in fibrous accumulations, resulting in a distinctive firm, smooth, irregularly-shaped scars.

Keloid scars are 1 to 2 millimeters in diameter, but some can reach 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 diminish in size over time.

Scars Generated by Loss of Tissue

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

Ice-pick Scars or Pitted Scars

Usually occur on the cheek. They are usually small, with characteristically jagged edges and steep side-like marks 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 quite large, with sharp edges and steep sides. The base of these scars is firm to the touch. Ice-pick scars may evolve into depressed fibrotic scars over time.

Soft scars

Superficial or deep and soft to the touch. 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 occur on the face, but may be a centimeter or larger on the body. They are soft, often with a slightly wrinkled base, and can 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 noticeable.

Follicular macular atrophy

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

Biological Ingredient Treats Acne Scars

You can try and treat this imbalance in tissue production with common chemical-based acne treatments that promise freeing your skin of acne breakouts, but that are incapable of treating the scars that are left behind after and acne inflammation has subsided. By using these products you will likely end-up with a drier skin texture that may present side-effects such as sun sensitivity, irritation or simply show no change at all. Your best bet is to use biological ingredients that bring collagen production back-up to normal and help 'disintegrate' and regenerate scarred tissue.

The majority of all regenerative ingredients contain natural oils, but only one ingredient is capable of supplying a balanced mix of ingredients that trigger skin rejuvenation. That miraculous ingredient comes from a snail and is considered the newest revolution in skin and scar treatment. Studies have shown that snail secretion contains a balanced mix of naturally occurring elastane, glycolic acid, allantoine, vitamins 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 treatments in the world haven't changed a thing, try using an natural ingredient that can help regenerate scarred skin.
