Lesions or scars left on facial skin, chest or back are usually caused by acne inflamation that has come and gone. There are two general 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 Caused by Exaggerated Tissue Generation.

The proliferation of scars caused by exaggerated tissue formation is called keloids. Keloid scars are associated to disproportioned amounts of the cell substance, collagen. The overproduction of collagen is the body's response to injured 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. Some people with relatives who have developed keloids scars are more susceptible to suffer from the same condition.

Keloid scars will be with you 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

Usually occur on the cheek. They are usually small, with characteristically jagged edges and steep side-like marks that seem to resemble an "ice-picked" shape. When touched, ice-pick scars may be soft or hard; they can affect the skin superficially, or reach the deeper layers. 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. 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 gently sloping rolled edges that merge with normal skin. They are usually 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 more on the body. They are soft, often with a slightly wrinkled base, and may be bluish in appearance because of the blood vessels lying just under the scar. Over time, these scars fade from bluish to ivory white in color in white-skinned people, so they 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 barely 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 or even years.

Acne Scars Treated with Natural Ingredient

Imbalanced tissue production can't be diminished 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 coarser texture that may present side-effects such as sun sensitivity, irritation or simply show no change at all. Your safest bet is to apply natural ingredients that bring collagen production back-up to normal and help dissolve and regenerate scars.

Most skin regenerative ingredients contain natural oils, but only one ingredient is capable of supplying a balanced mix of ingredients that trigger skin rejuvenation. That unbelievable component comes from a snail and is becoming the newest revolution in skin and scar treatment. Investigation has shown that snail secretion contains a balanced mix of naturally occurring elastane, allantoine, vitamins, glycolic acid and collagen, however, don't forget that complete scar renewal depends on the treatment itself and the extension of the scar.

So next time you look at your skin 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.
