Our skin is a seamless organ, like a fine piece of cloth cloaking valuable
assets. Any burn, injury, surgery or other trauma to it can cause the formation
of scar tissue that can be downright ugly.
Imagine if you had a fine piece of silk: Even one small tear can make a
difference in how it looks. But we're human: Throughout our lives, we will have
experiences that nip and tear at our skin, either self-inflicted, or completely
out of our control.
A scar isn't so bad if it's small or in a location that's easy to conceal.
But often you want a way to treat those scars other than hiding them under
clothing.
The truth is this: The scar will never completely go away, but there are
some methods that can help reduce its size and appearance.
How Does Scarring Happen?
Scar formation is a natural part of the healing process after injury.
Various factors influence how your skin scars. Of course, the depth and size
of the wound or incision and the location of the injury are going to impact the
scar's characteristics. But your age, heredity, even your sex or ethnicity,
will all affect how your skin reacts.
What Are the Types of Scars?
These are several different types of scars including:
Keloid scars.
These scars are the result of an overly aggressive
healing process. These scars extend beyond the original injury. Over time, a
keloid scar may affect mobility. Possible treatments include surgical removal,
or injections with steroids. Smaller keloids can be treated using cryotherapy
(freezing therapy using liquid nitrogen). You can also prevent keloid formation
by using pressure treatment or gel pads with silicone when you sustain an
injury. Keloid scars most often occur in Blacks.
Contracture scars. If your skin has been burned, you may have a
contracture scar, which causes tightening of skin that can impair your ability
to move; additionally, this type of scar may go deeper to affect muscles and
nerves.
Hypertrophic scars. Raised and red scars that are similar to
keloids, but do not breach the boundaries of the injury site. Possible
treatments can include injections of steroids to reduce inflammation.
Acne scars. If you've had severe acne, you probably have the scars
to prove it. There are many types of acne scars, ranging from deep pits to
scars that are angular or wavelike in appearance. Possible treatments will
depend on the types of acne scars you have.
Herpes simplex infections are common and when they appear around the mouth and lips, people often refer to them as "cold sores" and "fever blisters." Canker sores are different than cold sores. Air droplets can spread the virus, as can direct contact with the fluid from the blisters. Cold sore treatment include over-the-counter medication as well as prescription medications.
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.
Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis bacteria. Symptoms include weakness, fever, weight loss, night sweats and in worse cases, chest pain, shortness of breath, and coughing up blood. A person with an active infection (a positive TB skin test, abnormal chest x-ray and TB bacteria in their sputum) requires treatment with izoniazid, rifampin, ethambutol and pyrazinaide.
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous
system. When only the skin is involved, the condition is called discoid lupus.
When internal organs are involved, the condition is called systemic lupus
erythematosus (SLE).
Ingrown hairs may be caused by improper shaving, waxing or blockage of the hair follicle. Symptoms and signs of ingrown hairs include itching, tenderness, and small red pus bumps. Ingrown hairs usually heal on their own, but topical antibiotics, chemical depilatories, and hair-removal laser may be used in the treatment of ingrown hairs.
Impetigo is a contagious skin infection caused by staph and strep bacteria. There are two types of impetigo: non-bullous and bullous. Symptoms of non-bullous impetigo include small blisters on the nose, face, arms, or legs and possibly swollen glands. Bullous impetigo symptoms include blisters in various areas, particularly in the buttocks area. Treatment involves gentle cleansing, removing the crusts of popped blisters, and the application of prescription-strength mupirocin antibiotic ointment.
Melanoma is a type of skin cancer which begins in skin cells called melanocytes and affects more than 53,600 people in the United States each year. These melanocytes can grow together to form benign moles which, after a change in size, shape, or color can be a sign of melanoma. Caused by sun exposure, early detection becomes extremely important to avoid a spread to other areas of the body. Diagnosis is confirmed through a biopsy of the abnormal skin and treatment depends on the extent and characteristics of the patient.
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.
Keratosis pilaris (KP) is a common skin disorder in which small white or red bumps appear around hair follicles on the upper arms, thighs, buttocks, and cheeks. The cause of KP is unknown. There is no cure for keratosis pilaris, and the condition may resolve on its own. Gentle exfoliation, professional manual extraction, chemical peels, and microdermabrasion, along with topical products, are the best treatments for this condition.
Burns are categorized by severity as first, second, or third degree. First degree burns are similar to a painful sunburn. The damage is more severe with second degree burns, leading to blistering and more intense pain. The skin turns white and loses sensation with third degree burns. Burn treatment depends upon the location, total burn area, and intensity of the burn.
Ingrown toenails are caused by the growth of the toenail into the surrounding nail fold. Symptoms include toe pain, swelling, redness, and yellow drainage. Treatment at home involves soaking the affected foot in diluted white vinegar or Epsom salts, elevating the foot, and trimming the nails straight across. Surgery is also an option for severe cases. Prevent ingrown toenails by wearing shoes with a wider toe box and avoiding repeated injury to the toenails. Avoid curving or cutting the nails short at the edges.
Molluscum contagiosum is a skin infection caused by the poxvirus. Molluscum contagiosum appears as small tan or pink bumps on any part of the skin. Symptoms include a red or flushed appearance of the infected skin. Treatment may involve cryotherapy, manual extraction, surgical removal, the use of Retin-A, or the application of chemical acid.
Lichen sclerosus is a skin disease that causes white spots to form on the skin, which later grow into large, thin, and crinkled patches of skin that tear easily. Symptoms include itching, pain, blisters, and bleeding. Patches on the upper body usually go away over time, but patches in the genital region may scar if left untreated, causing problems with urination or sex. Treatment may involve surgery or the use of a very strong cortisone cream.
Moles are small skin growths that may appear flat or raised and are often tan, brown, black, reddish brown, or skin colored. They are typically about the size of a pencil eraser. There are three types of moles. Monthly skin self-exams are essential in the early detection of abnormal moles and melanomas.
A corneal ulcer is an open sore on the cornea. Infection is a common cause of corneal ulcer. Symptoms and signs of corneal ulcer include redness, eye pain and discharge, blurred vision, photophobia, and a gray or white spot on the cornea. Treatment depends upon the cause of the corneal ulcer.
Cleft palate and cleft lip are facial and oral defects that occur early in pregnancy. A cleft lip is a split of the two sides of the upper lip, and a cleft palate is a split in the roof of the mouth. Cleft lip the fourth most common birth defect in the U.S. Repair of a cleft palate or cleft lip may require multiple surgeries.
A urethral stricture, or narrowing of the urethra, may cause decreased urine output. Symptoms include painful urination, urinary retention, and pelvic pain. Surgery is the only treatment for people with uncontrolled symptoms of urethral narrowing.
Sunburn is caused by overexposure to UV radiation from the sun. UV rays can also damage the eyes. Repeated overexposure to UV rays also increases the risk for scarring, freckles, wrinkles, and dry skin. Symptoms of sunburn include painful, red, tender, and hot skin. The skin may blister, swell, and peel. Sun poisoning (severe sunburn) include nausea, fever, chills, rapid pulse, dizziness and more. Treatment for sunburn depends upon the severity. Sun protection and sunscreen for an individual's skin type is recommended to decrease the chance of sunburn.
Body dysmorphic disorder (BDD) is an illness where a person is overly preoccupied with some minor or imaginary flaw. People with BDD tend to have cosmetic surgery. BDD can be treated with SSRIs and cognitive behavioral therapy.
Leishmaniasis is a disease caused by the bite of an infected sand fly. The most common types of leishmania infection are cutaneous and visceral leishmaniasis. Leishmaniasis is found mainly in the subtropics and tropics. Symptoms and signs of cutaneous leishmaniasis include skin sores with a raised edge and central crater, while those with visceral leishmaniasis usually have fever, weight loss, and an enlarged liver and spleen.
Iritis is inflammation of the iris, the colored portion of the eye. Symptoms include a red, painful eye, blurry vision, and light sensitivity. Treatment usually involves cortisone eyedrops.
Yaws is an infectious disease that mainly occurs in the tropical areas of South and Central America, Asia, Africa, and the Pacific Islands. The disease is caused by a bacterium called Treponema pertenue, which causes lesions that look like bumps on the skin of the feet, hands, face, and genital area. Yaws is treated with penicillin or another antibiotic.
Monkeypox is a viral disease that causes symptoms such as fever, sweating, and a rash with papules and pustules on the face and chest. PCR, ELISA, or Western blot tests are used to diagnose monkeypox. Treatment usually involves administering a smallpox vaccination, cidofovir, and possibly vaccinia immune globulin.
Weber-Christian disease is a rare inflammatory disease that affects the body's fat tissues. It's also known as relapsing febrile nodular panniculitis syndrome and idiopathic lobular panniculitis. The disorder appears on the skin as red or purple tender, raised lumps. The thighs and lower legs are the most frequently affected areas. Other symptoms may include nausea, vomiting, weight loss, joint pain, and abdominal pain. Though there is no cure for the disease, inflammation may be treated with various antiinflammatory medications.
Factitious disorders are conditions in which people pretend to have physical or mental illnesses when they aren't sick. These people may lie about or fake symptoms to obtain the sympathy and attention given to people who are genuinely ill. Symptoms of factitious disorders include dramatic, inconsistent medical history, the presence of many surgical scars, and a history of seeking treatment at many different hospitals.
Smallpox is a disease caused by the variola virus. Symptoms and signs include a characteristic rash and high fever. Treatment focuses on supporting the patient. Smallpox may be prevented with the ACAM2000 smallpox vaccine.
Trachoma is an infectious disease caused by the Chlamydia trachomatis bacteria. Symptoms and signs include redness and irritation of the eyes with tearing. Trachoma is diagnosed by examining the eyes and eyelids. Treatment involves a single dose of azithromycin (Zithromax) or the use of topical tetracycline (Achromycin) ointment. Infected individuals should be counseled about sanitation and taught simple cleanliness.
Impetigo (pronounced im-puh-TIE-go) is a contagious, superficial infection of the skin caused by staphylococcus (Staph) and streptococcus (Strep) bacteria. Impetigo is more common in children (especially 2-
to 5-year-olds) than in adults. Impetigo is most likely to occur in warm and humid environments and is most commonly spread by close contact (such as family members).
What are the types of impetigo, and what are impetigo symptoms
and signs? What does impetigo look like?
There are two kinds of impetigo:
Non-bullous impetigo: This is the common form, caused by both Staph and
Strep bacteria. This form initially presents as small red papules similar to insect bites. These lesions rapidly evolve to small blisters and then to pustules that finally scab over with a characteristic honey-colored crust. This entire process takes about one week. These lesions often st...
