Laser Resurfacing Glossary of Terms

The following are health and medical definitions of terms that appear in the Laser Resurfacing article.

Acne: Localized skin inflammation as a result of overactivity of the oil glands at the base of hair follicles. Acne happens when oil (sebaceous) glands come to life around puberty, when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls.
See the entire definition of Acne

Anesthesia: Loss of feeling or awareness. A general anesthetic puts the person to sleep. A local anesthetic causes loss of feeling in a part of the body such as a tooth or an area of skin without affecting consciousness. Regional anesthesia numbs a larger part of the body such as a leg or arm, also without affecting consciousness. The term "conduction anesthesia" encompasses both local and regional anesthetic techniques. Many surgical procedures can be done with conduction anesthesia without significant pain. In many situations, such as a C-section, conduction anesthesia is safer and therefore preferable to general anesthesia. However, there are also many types of surgery in which general anesthesia is clearly appropriate.

Anesthetic: A substance that causes lack of feeling or awareness. A local anesthetic causes loss of feeling in a part of the body. A general anesthetic puts the person to sleep.

Antibiotic: A drug used to treat infections caused by bacteria and other microorganisms. Originally, an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another. Synthetic antibiotics, usually chemically related to natural antibiotics, have since been produced that accomplish comparable tasks.

Antiviral: An agent that kills a virus or that suppresses its ability to replicate and, hence, inhibits its capability to multiply and reproduce.
See the entire definition of Antiviral

Bacterial: Of or pertaining to bacteria. For example, a bacterial lung infection.

Bumps: The raised area of a bump or bruise results from blood leaking from these injured blood vessels into the tissues as well as from the body's response to the injury. A purplish, flat bruise that occurs when blood leaks out into the top layers of skin is referred to as an ecchymosis.

Cancer: An abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread).
See the entire definition of Cancer

Carbon dioxide: A gas which is the byproduct of cellular metabolism and which collects in the tissues, is cleared from the tissues by the blood within the veins, is carried by the hemoglobin in the red blood cells, and removed from the body via the lungs in the exhaled air. Abbreviated CO2.

Chest: The area of the body located between the neck and the abdomen. The chest contains the lungs, the heart and part of the aorta. The walls of the chest are supported by the dorsal vertebrae, the ribs, and the sternum.
See the entire definition of Chest

Cold sore: A small sore situated on the face or in the mouth that causes pain, burning, or itching before bursting and crusting over. The favorite locations are on the lips, chin or cheeks and in the nostrils. Less frequented sites are the gums or roof of the mouth (the palate).

Dermatology: 1. The branch of medicine concerned with the diagnosis, treatment, and prevention of diseases of the skin, hair, nails, oral cavity and genitals. 2. Sometimes also, cosmetic care and enhancement.
Dermatology is literally the study of the skin.

Elective: In medicine, something chosen (elected). An elective procedure is one that is chosen (elected) by the patient or physician that is advantageous to the patient but is not urgent.
See the entire definition of Elective

Facelift: A surgical procedure designed to make the face appear younger by pulling loose facial skin taut. With age or excessive sun exposure, wrinkled creased skin can develop on the face, neck or forehead along with fat deposits and folds around the jaws and jowls. While a facelift cannot stop the aging process, it may "turn back the clock" in appearance. Recovery time is usually 1 week, and the results last approximately 10 years. Additional procedures to supplement a facelift -- including necklift, blepharoplasty (eyelid surgery), liposuction, autologous fat injection, removal of buccal (cheek) fat pads, forehead lift, and browlift; chemical or laser peel; and malar (cheek), submalar, or chin implants -- may be necessary to achieve the desired results. Although they are infrequent, risks and complications of facelift surgery include bleeding; hematoma; bruising; infection; neurological dysfunction (loss of muscle function or sensation), which is usually temporary; widened or thickened scars; loss of hair around the incision site; asymmetry (unevenness between two sides); and skin necrosis (loss of skin due to tissue death).

Hyperpigmentation: Dark spots on the skin. Hyperpigmentation is primarily a cosmetic concern that can be covered with make-up, although in some cases (such as the cafe au lait spots associated with neurofibromatosis) it can be a sign of an underlying medical problem. If treatment of hyperpigmentation is desired, a dermatologist may be able to use dermabrasion, laser treatments, or bleaching agents to effect change.

Itching: An uncomfortable sensation in the skin that feels as if something is crawling on the skin or in the skin, and makes the person want to scratch the affected area.
See the entire definition of Itching

Laser: A powerful beam of light that can produce intense heat when focused at close range. Lasers are used in medicine in microsurgery, cauterization, for diagnostic purposes, etc. For example, lasers are employed in microsurgery to cut tissue and remove tissue.
See the entire definition of Laser

Lightening: Not to be confused with a discharge of atmospheric electricity, lightening refers to the sensation that a pregnant woman feels when the baby drops. This is the time when the presenting (lowermost) part of the fetus descends into the maternal pelvis.
See the entire definition of Lightening

Medical history: 1. In clinical medicine, the patient's past and present which may contain clues bearing on their health past, present, and future. The medical history, being an account of all medical events and problems a person has experienced, including psychiatric illness, is especially helpful when a differential diagnosis is needed.
2. The history of medicine.

Mouth: 1. The upper opening of the digestive tract, beginning with the lips and containing the teeth, gums, and tongue. Foodstuffs are broken down mechanically in the mouth by chewing and saliva is added as a lubricant. Saliva contains amylase, an enzyme that digests starch. 2. Any opening or aperture in the body. The mouth in both senses of the word is also called the os, the Latin word for an opening, or mouth. The o in os is pronounced as in hope. The genitive form of os is oris from which comes the word oral.

Neck: The part of the body joining the head to the shoulders. Also, any narrow or constricted part of a bone or organ that joins its parts as, for example, the neck of the femur bone.

Nose: The external midline projection from the face.
See the entire definition of Nose

Ointment: A medication preparation that is applied topically (onto the skin). An ointment has an oil base whereas a cream is water-soluble. (The word ointment comes from the Latin ungere meaning anoint with oil).

Outpatient: A patient who is not an inpatient (not hospitalized) but instead is cared for elsewhere -- as in a doctor's office, clinic, or day surgery center. The term outpatient dates back at least to 1715. Outpatient care today is also called ambulatory care.

Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia. Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.
See the entire definition of Pain

Pigment: A substance that gives color to tissue. Pigments are responsible for the color of skin, eyes, and hair.

Pigmentation: The coloring of the skin, hair, mucous membranes, and retina of the eye.
See the entire definition of Pigmentation

Rhinophyma: Pronounced (ryno-fee-ma), a bulbous enlarged red nose and puffy cheeks (like those of the old comedian W.C. Fields). There may also be thick bumps on the lower half of the nose and the nearby cheek areas. Rhinophyma occurs mainly in men as a complication of rosacea, a common chronic skin disease, and is best treated by surgery. The excess tissue is removed with a scalpel, laser or electrosurgery. Dermabrasion can help improve the final look of the tissue.
See the entire definition of Rhinophyma

Saline: Relating to salt. As an adjective, "saline" means "salty, containing salt." As a noun "saline" is a salt solution, often adjusted to the normal salinity of the human body.
See the entire definition of Saline

Sedative: A drug that calms a patient down, easing agitation and permitting sleep. Sedatives generally work by modulating signals within the central nervous system. These sedatives can dangerously depress important signals needed to maintain heart and lung function if they are misused or accidentally combined, as in the case of combining prescription sedatives with alcohol. Most sedatives also have addictive potential. For these reasons, sedatives should be used under supervision, and only as needed.

  • Related Diseases & Conditions

    • Acne (Pimples)
      • Acne is a localized skin inflammation as a result of overactivity of oil glands at the base of hair follicles. This inflammation, depending on its location, can take the form of a superficial pustule (contains pus), a pimple, a deeper cyst, congested pores, whiteheads, or blackheads. Treatments vary depending on the severity of the acne.
    • Warts (Common Warts)
      • Common warts are skin growths causes by the human papillomavirus. There are many types of warts, including plantar warts, common hand warts, warts under the nails, mosaic wars, and flat warts. Over-the-counter treatments typically involve the use of salicylic acid products.
    • Keloid
      • A keloid is a scar that doesn't know when to stop. When the cells keep on reproducing, the result is an overgrown (hypertrophic) scar or a keloid. A keloid looks shiny and is often dome-shaped, ranging in color from slightly pink to red. It feels hard and thick and is always raised above the surrounding skin.
    • Birthmark
      • Birthmarks and other abnormal skin pigmentation is caused by the body's inability to produce enough melanin. Abnormal skin pigmentation can cause conditions such as vitiligo, pigmentation loss, melasma, albinism, port wine stains, macular stains and hemangioma.
    • Scars
      • Scar formation is a natural part of the healing process after injury. The depth and size of the wound incision and the location of the injury impact the scar's characteristics, but your age, heredity and even sex or ethnicity will affect how your skin reacts.
    • Wrinkles
      • Wrinkles, whether they be fine line or deep furrows, typically appear on areas of the body that receive a high amount of exposure to the sun. Smoking, light skin type, hairstyle, the way you dress, your occupational and recreational habits, and heredity are all factors that promote wrinkling. Medical treatments for wrinkles include antioxidants, moisturizers, alpha-hydroxy acids, and vitamin A acid. Cosmetic procedures that treat wrinkles include dermabrasion, microdermabrasion, glycolic acid peels, laser resurfacing, Botox, and fillers.

Introduction to Liposuction

"The battle of the bulge." That tiny, five-word phrase has been shoved in our faces for years, thanks to television, newspapers and magazines. But sometimes, no matter how hard you fight, the bulge has a tougher army. The fact is that certain people have fat cells that will not shrink, despite diet and exercise. You can thank heredity for that in some cases.

Liposuction is an option to remove small bulges that won't budge and to improve your body's shape. The areas most commonly treated include the hips, abdomen, thighs and buttocks and face. Liposuction does not remove cellulite, only fat.

Who Is a Good Candidate For Liposuction?

A good candidate for liposuction should have realistic expectations about the results of this procedure as well as these basic qualities:
