Biological Treatment of Acne Scars

The best way of treating acne scars is to start early and continue for as long as is necessary. There are, however, a number of treatments available when suffering from scar formation. The idea behind biological acne scarring treatment is that old, damaged tissues and scars are replaced by new cells. Some topical treatments contain ingredients that start this chain of events. These treatments focus on the creation of healthy skin cells instead of aggravating the body´s inflammatory immune system response. The natural ingredients can saturate deep into the skin and promote cellular turnover. Damaged tissues and acne scars are diffused into their own amino acid components and released back into the body as the basis of new cellular growth. One step in the healing process involves an enzyme that starts a metabolic effect and a signal transduction that triggers the process of skin repair and skin remodeling. This metabolism works with extremely complex sequences of controlled biochemical modification of chemical compounds in living organisms and cells. Through these metabolic processes the enzymes can affect how fast a swelling or an edema of injured tissue is reduced. They do this by “digesting” or breaking down the damaged tissue. The waste material is thereby removed from the skin lesions so as to reduce inflammation, speed up the healing process and encourage regeneration of new tissue. In biology, signal transduction is any process by which a cell converts one kind of signal or stimulus into another. These processes often involve a sequence of biochemical reactions inside the cell. These reactions are carried out by enzymes and linked through second messengers. The processes can last a millisecond or as long as a few seconds. In transduction processes, an increasing number of enzymes and other molecules become engaged in the events that proceed from the initial stimulus. In such cases the chain of steps is referred to as a "signaling cascade" and often results in a small stimulus eliciting a large response. So, biological ingredients with active parts like antioxidants, anti-inflammatory, proteins, peptides, and enzymes can with rather little effort stimulate the speed in which the body heals itself.
Improved exchange between cells promotes proliferation which improves collagen and elastin levels in the skin. Biological ingredients will fuse with the skin cells and stimulate the production of fibroblasts which provide the structural framework for the skin. It dissolves existing post inflammatory scars and also fills in depressed scarring. The biological ingredients do this by stimulating the replacement of damaged skin cells, getting rid of scarring and necrotic tissues. They also stimulate the formation of the extra cellular binding between cells, thus improving skin strength, cutting down on fragility, and inhibit microbiological activity of dangerous, pathogenic skin bacteria, including acne.

Dermabrasion is a cosmetic medical procedure in which the surface of the skin is removed by abrasion (sanding). It is used to remove sun-damaged skin and to remove or lessen scars and dark spots on the skin. The procedure is very painful and usually requires a general anaesthetic or twilight anaesthesia, in which the patient is still partly conscious[1] Afterward, the skin is very red and raw-looking, and it takes several months for the skin to regrow and heal. Dermabrasion is useful for scar removal when the scar is raised above the surrounding skin, but is less effective with sunken scars.

In the past, dermabrasion was done using a small, sterilized, electric sander. In the past decade, it has become more common to use a CO2 or Erbium:YAG laser. Laser dermabrasion is much easier to control, much easier to gauge, and is practically bloodless compared to classic dermabrasion.

Microdermabrasion comes from the above mentioned technique dermabrasion. Microdermabrasion is a more natural skin care that is a gentler, less invasive technology for doing an exfoliation on the skin. The goal of the microdermabrasion is to eliminate the superficial layer of the skin called the epidermis. If the surface of the abraded skin is touched, a roughness of the skin will be noticed. The roughness is keratinocytes, which are better hydrated than the surface corneocytes. Keratinocytes appear in the basal layer from the proliferation of keratinocyte stem cells. They are pushed up through the cells of the epidermis, experiencing gradual specialization until they reach the stratum corneum where they form a layer of dead, flattened, strongly keratinized cells called squamous cells. This layer creates an efficient barrier to the entry of foreign matter and infectious elements into the body and reduces moisture loss. Keratinocytes are shed and restored continuously from the stratum corneum. The time of transit from basal layer to shedding is generally one month. Corneocytes are cells derived from keratinocytes in the late stages of terminal specialization of squamous epithelia. The microdermabrasion is done to eliminate some of the corneocytes. These cells are responsible for the impermeability of the skin. The minimizing or elimination of scars, skin lesions, blotchiness and stretch marks from the skin can be an easy process with the use of skin exfoliation. The result depends on how well the procedure known as "skin remodeling" works. Results are optimal and fewer treatments are needed with more recent and/or superficial scars. Still, microdermabrasion can be used on scars that showed up during puberty or many years later.

Laser therapy
Fractional Laser resurfacing is a procedure which wounds the skin using microscopic pulses of light. Over the course of several treatments scars are softened as the body regenerates the areas of microthermal wounding. Several lasers are now on the market such as the Fraxel Laser, Affirm Laser, and Pixel Laser.
Laser resurfacing is a technique used during laser surgery wherein molecular bonds of a material are dissolved by a laser.

Chemical therapy
Chemical peels improve and smooth the texture of the facial skin using a chemical solution that causes the skin to blister and eventually peel off. The regenerated skin is usually smoother and less wrinkled and scarred than the old skin.

Surgical therapy
Subcision is a process used to treat deep rolling scars left behind by acne or other skin diseases. Essentially the process involves separating the skin tissue in the affected area from the deeper scar tissue. This allows the blood to pool under the affected area, eventually causing the deep rolling scar to level off with the rest of the skin area. Once the skin has leveled, treatments such as laser resurfacing, microdermabrasion or chemical peels can be used to smooth out the scarred tissue.

Preparing for surgery can be a big undertaking. As part of your preparation don't forget to get all your questions answered before the surgery.
