Just before speaking about scars, a word about spots that could look like scars but are not scars in the sense that a permanent adjust has occurred. Even even though they are not accurate scars and disappear in time, they are visible and can lead to embarrassment.

Macules or "pseudo-scars" are flat, red or reddish spots that are the final stage of most inflamed acne lesions. Right after an inflamed acne lesion flattens, a macule may remain to "mark the spot" for up to 6 months. When the macule at some point disappears, no trace of it will remainunlike a scar.

It happens far more often in darker-skinned people, but sometimes is seen in individuals with white skin. Early remedy by a dermatologist might lessen the development of post-inflammatory pigmentation. Some post-inflammatory pigmentation might persist for up to 18 months, specifically with excessive sun exposure. Chemical peeling may hasten the disappearance of post-inflammatory pigmentation.

Causes of Acne Scars

In the simplest terms, scars form at the site of an injury to tissue. They are the visible reminders of injury and tissue repair. In the case of acne, the injury is brought on by the bodys inflammatory response to sebum, bacteria and dead cells in the plugged sebaceous follicle. Two kinds of correct scars exist, as discussed later: (1) depressed areas such as ice-pick scars, and (two) raised thickened tissue such as keloids.

When tissue suffers an injury, the physique rushes its repair kit to the injury site. Among the components of the repair kit are white blood cells and an array of inflammatory molecules that have the task of repairing tissue and fighting infection. Even so, when their job is completed they could leave a somewhat messy repair internet site in the form of fibrous scar tissue, or eroded tissue.

White blood cells and inflammatory molecules may possibly stay at the web site of an active acne lesion for days or even weeks. In people who are susceptible to scarring, the outcome may be an acne scar. The occurrence and incidence of scarring is nonetheless not well understood, nonetheless. There is considerable variation in scarring between 1 particular person and another, indicating that some individuals are more prone to scarring than other individuals. Scarring frequently results from extreme inflammatory nodulocystic acne that happens deep in the skin. But, scarring also could arise from a lot more superficial inflamed lesions. Nodulocystic acne that is most probably to result in scars is noticed in these photographs:

The life history of scars also is not properly understood. Some folks bear their acne scars for a lifetime with small change in the scars, but in other individuals the skin undergoes some degree of remodeling and acne scars diminish in size.

People also have differing feelings about acne scars. Scars of much more or much less the exact same size that may be psychologically distressing to a single person could be accepted by one more particular person as "not as well negative." The individual who is distressed by scars is more likely to seek therapy to moderate or take away the scars.

Prevention of Acne Scars

As discussed in the prior section on Causes of Acne Scars, the occurrence of scarring is diverse in distinct people. It is difficult to predict who will scar, how comprehensive or deep scars will be, and how extended scars will persist. It is also tough to predict how successfully scars can be prevented by productive acne treatment.

Nonetheless, the only sure method of preventing or limiting the extent of scars is to treat acne early in its course, and as extended as essential. The more that inflammation can be prevented or moderated, the more likely it is that scars can be prevented.

Varieties of Acne Scars

There are two general kinds of acne scars, defined by tissue response to inflammation: (1) scars triggered by improved tissue formation, and (two) scars caused by loss of tissue.

Scars Induced by Enhanced Tissue Formation

The scars caused by increased tissue formation are referred to as keloids or hypertrophic scars. The word hypertrophy means "enlargement" or "overgrowth." Each hypertrophic and keloid scars are associated with excessive amounts of the cell substance collagen. Overproduction of collagen is a response of skin cells to injury. The excess collagen becomes piled up in fibrous masses, resulting in a characteristic firm, smooth, normally irregularly-shaped scar. The photo shows a common extreme acne keloid:

The common keloid or hypertrophic scar is 1 to two millimeters in diameter, but some might be 1 centimeter or more substantial. Keloid scars tend to "run in households"that is, abnormal growth of scar tissue is much more most likely to take place in susceptible folks, who typically are people with relatives who have similar varieties of scars.

Hypertrophic and keloid scars persist for years, but might diminish in size more than time.

Scars Triggered by Loss of Tissue

Acne scars associated with loss of tissuesimilar to scars that outcome from chicken poxare more common than keloids and hypertrophic scars. Scars related with loss of tissue are:

Ice-choose scars generally occur on the cheek. They are typically tiny, with a somewhat jagged edge and steep sideslike wounds from an ice choose. Ice-pick scars may be shallow or deep, and may be tough or soft to the touch. Soft scars can be enhanced by stretching the skin difficult ice-pick scars can not be stretched out.

Depressed fibrotic scars are generally quite large, with sharp edges and steep sides. The base of these scars is firm to the touch. Ice-choose scars could evolve into depressed fibrotic scars more than time.

Soft scars, superficial or deep are soft to the touch. They have gently sloping rolled edges that merge with regular skin. They are normally small, and either circular or linear in shape.

Atrophic macules are usually fairly tiny when they happen on the face, but could be a centimeter or more substantial on the physique. They are soft, often with a slightly wrinkled base, and might be bluish in appearance due to blood vessels lying just beneath the scar. Over time, these scars alter from bluish to ivory white in color in white-skinned men and women, and grow to be significantly less obvious.

Follicular macular atrophy is much more likely to take place on the chest or back of a individual with acne. These are small, white, soft lesions, often barely raised above the surface of the skinsomewhat like whiteheads that didnt totally create. This situation is often also named "perifollicular elastolysis." The lesions could persist for months to years.

Remedies for Acne Scars

A quantity of remedies are available for acne scars by means of dermatologic surgery. The variety of treatment selected really should be the 1 that is very best for you in terms of your variety of skin, the cost, what you want the treatment to accomplish, and the possibility that some types of remedy may possibly outcome in more scarring if you are very susceptible to scar formation.

The scar treatments that are at the moment available contain:

Collagen injection. Collagen, a standard substance of the physique, is injected below the skin to "stretch" and "fill out" specific types of superficial and deep soft scars. Collagen therapy usually does not operate as effectively for ice-choose scars and keloids. Collagen derived from cows or other non-human sources can not be utilized in folks with autoimmune diseases. Human collagen or fascia is beneficial for those allergic to cow-derived collagen. Cosmetic advantage from collagen injection typically lasts three to 6 months. Added collagen injections to maintain the cosmetic benefit are accomplished at further price.

Autologous fat transfer. Fat is taken from another web site on your personal body and prepared for injection into your skin. The fat is injected beneath the surface of the skin to elevate depressed scars. This method of autologous (from your personal physique) fat transfer is usually used to right deep contour defects triggered by scarring from nodulocystic acne. Simply because the fat is reabsorbed into the skin more than a period of 6 to 18 months, the process usually should be repeated. Longer lasting results may be attained with multiple fat-transfer procedures. purchase acne scar cream

Dermabrasion. This is thought to be the most successful therapy for acne scars. Beneath local anesthetic, a high-speed brush or fraise utilized to take away surface skin and alter the contour of scars. Superficial scars could be removed altogether, and deeper scars may possibly be lowered in depth. Dermabrasion does not operate for all types of scars for instance, it could make ice-choose scars more noticeable if the scars are wider under the skin than at the surface. In darker-skinned people, dermabrasion may result in adjustments in pigmentation that demand added treatment.

Microdermabrasion. This new strategy is a surface form of dermabrasion. Rather than a higher-speed brush, microdermabrasion utilizes aluminum oxide crystals passing by way of a vacuum tube to remove surface skin. Only the extremely surface cells of the skin are removed, so no added wound is made. A number of procedures are frequently necessary but scars may possibly not be considerably improved.

Laser Therapy. Lasers of various wavelength and intensity may possibly be utilised to recontour scar tissue and minimize the redness of skin around healed acne lesions. The kind of laser used is determined by the outcomes that the laser treatment aims to accomplish. Tissue may really be removed with far more potent instruments such as the carbon dioxide laser. In some instances, a single treatment is all that will be required to attain permanent outcomes. Since the skin absorbs powerful bursts of power from the laser, there might be post-treatment redness for numerous months.

Skin Surgery. Some ice-pick scars might be removed by "punch" excision of each individual scar. In this procedure each and every scar is excised down to the layer of subcutaneous fat the resulting hole in the skin may possibly be repaired with sutures or with a small skin graft. Subcision is a technique in which a surgical probe is utilised to lift the scar tissue away from unscarred skin, as a result elevating a depressed scar.

Skin grafting may possibly be required under certain conditionsfor instance, at times dermabrasion unroofs enormous and comprehensive tunnels (also named sinus tracts) caused by inflammatory reaction to sebum and bacteria in sebaceous follicles. Skin grafting could be required to close the defect of the unroofed sinus tracts.

Treatment of keloids. Surgical removal is seldom if ever utilized to treat keloids. A person whose skin has a tendency to type keloids from acne harm could also type keloids in response to skin surgery. Sometimes keloids are treated by injecting steroid drugs into the skin around the keloid. Topical retinoic acid may possibly be applied straight on the keloid. In some circumstances the very best therapy for keloids in a extremely susceptible individual is no therapy at all.

In summary, acne scars are induced by the bodys inflammatory response to acne lesions. The greatest way to avert scars is to treat acne early, and as extended as necessary. If scars kind, a number of successful treatments are accessible. Dermatologic surgery remedies must be discussed with a dermatologist.
