Scarifying involves scratching, etching, or some sort of superficial cutting or incision. Scarification can be applied to horticulture, which involves cutting the seed coat using acid, sand paper, or a knife to encourage germination, the cutting of concrete using hydrodemolition, or as a permanent body modification, etching designs, pictures, or words into the skin. Horticulture is the art and science of plant cultivation Horticulturists (or horticuluralists) work and conduct research in the fields of Plant propagation Germination is the process whereby growth emerges from a period of dormancy Hydrodemolition (also known as hydro demolition hydroblasting hydro blasting hydromilling waterblasting and waterjetting is a Concrete removal technique which utilizes Body modification (or body alteration) is the permanent or semi-permanent deliberate altering of the human body for non-medical reasons such as sexual enhancement

Scarification in construction

Scarification of concrete can be done using hydrodemolition, aka hydro scarification, and high speed scarification. Hydrodemolition (also known as hydro demolition hydroblasting hydro blasting hydromilling waterblasting and waterjetting is a Concrete removal technique which utilizes The depth of removal depends on the application, but usually does not exceed 1/4" to 3/4". The use of scarification on concrete is used to provide a better bond profile with an overlay of the same material. Scarification sometimes follows an initial milling of a surface using a large mechanical grinder. The hydro scarification following this process can have the effect of eliminating microfractures produced by the impact of the milling machine. The absence of micofractures and the creation of a better bond profile, both help to create a better bond strength with the concrete overlay.

Scarification as a body modification

See also: Body modification

In the process of body scarification, scars are formed by cutting or branding the skin. Body modification (or body alteration) is the permanent or semi-permanent deliberate altering of the human body for non-medical reasons such as sexual enhancement Cutting is the separation of a physical object or a portion of a physical object into two portions through the application of an acutely directed force Human branding is the process in which a mark usually a symbol or ornamental pattern is burned into the skin of a living person with the intention that the resulting scar makes it permanent Scarification is sometimes called cicatrization (from the French equivalent).

Scarification has been used for many reasons in many different cultures:

Reasons

There are many reasons why people may turn to scarification. Aesthetically, scarifications are usually more visible on darker skinned people than tattoos. Also, unlike tattoos, scarifications are a product of one's own body. Endorphins are released in the process of obtaining the scars that can put a person into a high or euphoria. Endorphins are Endogenous Opioid Polypeptide compounds They are produced by the Pituitary gland and the Hypothalamus in Vertebrates Euphoria is a medically recognized emotional state related to Pleasure and Happiness.

There are also religious and social reasons for scarification. According to some tribal belief in Africa, producing scars on newborn children helps preventing vision related illness. There may also be religious expressions used in the scarification process.

Methods

Scarification is not a precise art; there are many variables, such as skin type, depth of the cut, and how the wound is treated while healing, that make the outcome somewhat unpredictable.

The body creates the scar, not the artist; it is important to keep in mind that a method that works well on one person may not work so well on another. Also, the scars tend to spread a bit as they heal, so scarifications are usually relatively simple designs -- small details can easily get swallowed up in the healing process.

Branding

Human branding is one type of scarification. Human branding is the process in which a mark usually a symbol or ornamental pattern is burned into the skin of a living person with the intention that the resulting scar makes it permanent It is similar in nature to livestock branding. Livestock branding is any technique for marking Livestock so as to identify the owner

Strike branding
This is basically the same process used to brand livestock. A piece of metal is heated and pressed onto the skin for the brand. However, the brand is usually done piece by piece rather than all at once. For example, to get a V-shaped brand, two lines would be burned separately by a straight piece of metal, rather than by a V-shaped piece of metal.
Cautery branding
This is a less common form of branding that uses a tool similar to a cautery-iron to cause the burns.
Laser branding
The technical term for laser branding is "electrocautery branding". The electrocautery unit is more like an arc welder for skin than a medical laser (though it is possible to use a medical laser for scarification). Electric sparks jump from the device to the skin, vaporizing the skin. This is a more precise form of scarification, because it is possible to regulate the depth and nature of the skin damage being done to it.
Cold branding
This rare method of branding is the same thing as strike branding, except that the metal branding tool is subjected to extreme cold (such as liquid nitrogen) rather than extreme heat. Liquid nitrogen (liquid density at the Triple point is 0707 g/mL is the liquid produced industrially in large quantities by Fractional distillation of This method will cause the hair on the brand to grow back white and will not cause any keloiding. A keloid is a type of Hypertrophic scar with mainly type I and some type III collagen which results in an overgrowth of tissue at the site of a healed skin injury

Cutting of the skin for cosmetic purposes is not to be confused with self-injury, which is also referred to by the euphemism "cutting. Self-injury ( SI) or self-harm ( SH) is deliberate Injury inflicted by a person upon their own body without suicidal intent A euphemism is a substitution of an agreeable or less offensive expression in place of one that may offend or suggest something unpleasant to the listener or in the case of doublespeak " However, there may be borderline cases of artistic self-injury and self-scarification for internal, non-cosmetic reasons.

Lines are cut with surgical blades. Extended cutting techniques include:

Ink rubbing
This is where tattoo ink (or another sterile coloring agent) is rubbed into a fresh cut. Most of this ink will remain in the skin as the cut heals, and will have the same basic effect as a tattoo. As with tattoos, it is important not to pick the scabs as this will pull out the ink. The general public often interprets ink-rubbings as poorly done tattoos.
Skin removal/skinning
Cutting in single lines produces relatively thin scars, and skin removal is a way to get a larger area of scar tissue. The outlines of the area of skin to be removed will be cut, and then the skin to be removed will be peeled away. Scars from this method often have an inconsistent texture.
Packing
This method is uncommon in the West, but has traditionally been used in Africa. A cut is made diagonally and an inert material such as clay or ash is packed into the wound; massive keloids are formed during healing as the wound pushes out the substance that had been inserted into the wound. A keloid is a type of Hypertrophic scar with mainly type I and some type III collagen which results in an overgrowth of tissue at the site of a healed skin injury Cigar ash is commonly used in the United States for more raised and purple scars; people may also use ashes of deceased loved ones.

Abrasion

Scars can be formed by removing layers of skin through abrasion. This can be achieved using a tattooing device (with no ink), or any object that can remove skin through friction (such as sandpaper). It is somewhat common for people who wish to experiment with performing their own scarifications to scrape away skin into a desired pattern with a needle or pin. This method of self-scarification is not recommended as it is unsafe.

Chemical scarification uses corrosive chemicals to remove skin and induce scarring. The effects of this method are typically very similar to other, simpler forms of scarification; as a result there has been little research undertaken on this method.

Healing

The common opinion on healing a scarification wound is that it should be treated with irritation.

Irritation
Generally, the longer it takes a wound to heal, the more pronounced (the darker or more raised) the scar will be. Therefore, in order to have very pronounced scars, the goal is to keep the wound open and healing for the longest time possible. This is done by picking or scrubbing away scabs and irritating the wound with chemical or natural irritants such as toothpaste or citrus juice. Some practitioners recommend the use of tincture of iodine which has been proven to cause more visible scarring (this is why it's no longer used for treating minor wounds). With this method, a wound may take months to heal; however the scar may be inconsistent.
Keloids
Keloids are raised scars. A keloid is a type of Hypertrophic scar with mainly type I and some type III collagen which results in an overgrowth of tissue at the site of a healed skin injury Keloiding can be a result of genetics, skin color (darker skin types are more prone to keloiding), or irritation. Keloids are often desired for the visual, 3-D effect they provide and for the way they feel to the touch.
Touch-ups
If a scarification does not heal in the desired fashion, secondary scarifications may be done to help achieve the desired effect, such as even scarring, or detail.

An alternative view is described by the acronym LITHA, meaning Leave It The Hell Alone. In body modification this is often considered the best way to reduce the risk of infection and the pain of healing.

Dangers/cautions

Scarification is intentionally causing harm or trauma to the skin; thus it is not safe.
