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 response to inflammation:

(1) Scars generated by exaggerated tissue formation, and

(2) Scars generated by loss of tissue.

Scars Generated by Exaggerated Tissue Generation.

The creation of scars caused by exaggerated tissue formation is known as keloids. Keloid scars are linked to disproportioned amounts of the cell substance, collagen. The overproduction of collagen is the body's response to damaged skin cells. This excess becomes piled up in fibrous accumulations, resulting in a distinctive firm, smooth, irregularly-shaped scars.

The typical keloid scar is 1 to 2 millimeters in diameter, but some may be 1 centimeter or larger. Some people with relatives who have developed keloids scars are more susceptible to suffer from the same condition.

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 typical than keloids. Scars linked with loss of tissue are:

Ice-pick Scars or Pitted Scars

Usually appear on the cheek. They are usually small, with visible jagged edges and steep side-like marks that seem to resemble 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 treated 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 evolve into depressed fibrotic scars over time.

Soft scars

Superficial or deep and soft to the touch. They have gently 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 more on the body. They are soft, usually 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 noticeable.

Follicular macular atrophy

They are more likely to appear 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 somewhat like whiteheads that did not fully develop. This condition is sometimes also known as "perifollicular elastolysis." The lesions may persist for months or even years.

Acne Scars Treated with Natural Ingredient

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 coarser texture that may present side-effects such as sun sensitivity, irritation or simply show no change at all. Your best bet is to apply biological ingredients that bring collagen production back-up to normal and help dissolve 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 repair. That miracle ingredient comes from a snail and is considered the newest revolution in skin and scar treatment. Investigation has shown that snail secretion contains a combination of naturally occurring vitamins, allantoine, 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 treatments in the world haven't changed a thing, try using an natural ingredient that treats and regenerates scarred skin.
