Dermatologist
A physician who treats these disorders and diseases.
Estheticians can NOT Perform
Any services on clients who have contagious or infections diseases.

Lesions
Structural changes in the tissues caused by damage or injury. Any mark, wound or abnormality is also described as a lesion.
3 Types of Lesions
Primary, Secondary, & Tertiary
Primary Lesion
Lesions in early stages of development or change.
Primary Lesions Characterized by:
Flat, nonpalpable changes in skin color or by elevations formed by fluid in a cavity, such as vesicles or pustules.
Bulla
Large blister containing watery fluid. Similar to vesicle, but larger
Cyst
Closed, abnormally developed sac containing fluid, infection, or other matter above or below the skin.
Macule
Flat spot or discoloration of the skin. Natural freckles, can also be red.
Nodules
Smaller than tumors, caused by conditions such as scar tissues, fatty deposits or infections.
Papule
Small elevations on the skin that contains no fluids, but may develop into a pustule. Less than a half an inch in diameter, and may have varied appearance in color and are either rounded, smooth or rough.
Pustule
Inflamed papule with a white or yellow center containing puss. Fluid consisting of white blood cells, bacteria and other debris. Small pus-contained blister that may or may not be caused by an infections. Acne pustules in hair follicles are not infectious.
Tubercle
Abnormal rounded, solid lump; larger than papule.
Tumor
Large nodule, abnormal cell mass resulting from excessive cell multiplication, varying in size, shape, and color.
Vesicle
Small blister or sac containing clear fluid. Poison ivy produces vesicles.
Wheal
Itchy swollen lesion caused by a blow, insect bite, skin allergy reaction or stings. Hives, and mosquito bites are wheals.
Urticaria
Hives, can also be caused by exposure to allergens used in products.
Secondary Lesions
Skin damage, developed in the later stages of disease, that changes the structure of tissues or organs. Later stages of disease and change the structure of tissues and organs.
Vascular Lesion
Involve the blood or circulatory system.
Tertiary Lesions
AKA Vascular lesions, involve the blood or circulatory system.
Crust
“Scabs” Dead cells formed over a wound or blemish while it is healing. Accumulated of sebum pus, and sometimes mixed with epidermal material.
Excoriation
Skin sore or abrasion produced by scratching or scraping.
Acne Excoriation
Disorder where clients purposely scrape off acne lesions, causing scarring, and discoloration.
Fissure
Crack in the skin that may penetrate into the dermis. Chapped lips, cracked heals, and hands, are examples.
Keloid
Thick scar resulting from excessive growth of fibrous tissue (collagen) Usually found in those that are genetically predisposed to them, and may occur following an injury or surgery (Usually Fitz VI)
Scale
Excessive shedding of dead skin cells; flaky skin cells; any thing plate of epidermal flakes, dry or oily. Example dandruff or psoriasis
Scar
Discolored, slightly raised mark on the skin formed after an injury or lesion of the skin has healed. Tissue hardens to heal the injury.
Hypertrophic
Thick elevated scars.
Ulcer
Open lesion on the skin or mucous membrane of the body accompanied by pus and loss of skin depth; deep erosion or depression in the skin. Normally due to infection or cancer. Requires medical referral.
Disorders of the Sebaceous (oil) glands include:
Acne, Asteatosis, Comedones, Furuncle, Carbuncles, Milia, Sebaceous Hyperplasia, Seborrhea, Seborriheic Dermatitis, Steatoma.
Acne
Chronic infammatory skin disorder of the sebaceeous glands. Characterized by comedones, and blemishes. Inflammation of sebaceous glands results from retained oil secretions, cells, and excessive Propionibacterium acne (P.acne) bac
Common Acne is known as:
Acne simplex, or Acne Vulgaris
Propionibacterium Acne
(P. acne) Bacteria
Asteatosis
Dry, scaly skin from sebum deficiency; can be due to aging, internal disorders, alkalies of harsh soaps or cold exposure.
Comedo (Comedones; plural)
Noninflamed buildup of cells, sebum, and other debris inside follicles.
Open Comedo
Blackhead open at the surface and exposed to air. The follicle is filled with an excess of oil a blackhead forms. Dark color is dues to oxidation occurring.
Closed Comedo
Openings of follicles are blocked with debris and white cells. AKA Whitehead.
Furuncle

Carbuncles
Groups of boils.
Milia
Epidermal cysts that are small, firm white papules. Whitish, pearl-like masses of sebum and dead cells under the skin. No visible opening, often mistakenly called whiteheads. (whiteheads are softer) Hardened and closed over. Common in dry skin types. Has to be lanced or opened to extract.
Sebaceous Hyperplasia
Benign lesions frequently seen in oilier areas of face. Often white, yellow or flesh colored. Described as doughnut-shaped with an indentation in the center. Sebaceous material may be found in the center. Harmless lesions that cannot be extracted. Has to be removed surgically.
Seborrhea
Severe oiliness of the skin.
Seborrheic Dermatitis
Inflammation, dry or oily scaling or crusting, and itchiness. Red flaky skin often appears in the eyebrows, scalp, hair line, the middles of the forehead and along sides of the nose. Sometimes treated with cortisone creams. Sever cases should be referred to a dermatologist. Commonly known as eczema.

3 Main categories of Dermatitis
Atopic, Contact, & Seborrheic
Atopic Dermatits
Chronic relapsing from of dermatitis. “excess inflammation due to allergies” Irritants and allergens that trigger reactions that include dry cracking skin.
Dehydration makes worse, use humidifiers and lotion to keep skin hydrated.

Perioral Dermatitis
Acne-like condition around the mouth; consists of mainly small clusters of papules, not contagious. Antibiotics can help condition.
Eczema
Painful itching disease of the skin; acute or chronic in nature, with dry or moist lesions. Refer to physician. AKA Seborrheic dermatitis, also a sebaceous gland disorder.
Characteristics: Scaling around, nose, ears, scalp, eyebrows, and mid-chest areas. Flaking mainly affects oilier areas.
Edema
Swelling from fluid imbalance in cells. Response to injury, infection, or medication.
Erythema
Redness caused by inflammation.
Folliculitis
Hair that grows under the surface instead of growing up and out of the follicle, causing a bacterial infection. “Ingrown hairs”
Pseudofolliculitis
“Razor bumps” Resembles folliculitus without the pus or infection.
Pruitis
Medical term for itching; persistent itching.
Psoriasis (Suh-ry-uh-sis)
Itchy skin disease characterized by red patches covered with white-silver scales. Usually found in patches on the scalp, elbows, knees, chest and lower pack. Not contagious but can be spread by irritating affected area.
Vascular Lesions Include:
Rosacea, Telangiectasia, Vasodilation, Varicose Veins.
Rosacea
Inflammation of the skin characterized by extreme redness, dilation of blood vessels. In sever cases formation of papules and pustules.
Rosacea Cause
Unknown but may be due to heredity, bacteria, mites, or fungus.
What aggravates Rosacea?
Spicy foods, alcohol, caffeine, extreme temperatures, heat, sun, and stress.
Vasodilation
Vascular dilation of the blood vessels.
Telangiectasia
Vascular lesion, capillaries that have been damaged and are now larger or distended blood vessels. Commonly called “Couperose Skin”
Couperose Skin
Telangiectasia
Varicose Veins
Vascular lesions that are abnormally dilated, and twisted veins which can occur anywhere in the body. Sometimes treated with “sclerotherapy” Surgery is an option for serious cases.
Sclerotherapy
Nonsurgical injection into the vein.
Allergic Contact Dermatitis
Exposure, and direct skin contact to an allergen.
Irritant Contact Dermatitis- What happens?
Immune system floods the tissue with water trying to dilute the irritant (why swell occurs.) Also releases histamines, which enlarge the vessels around injury.
What do histamines do?
Cause itchy feeling that often accompanies contact dermatitis.
Pigmentation Disorders (3)
Dyschromia, Hyperpigmentation, Hypopigmentation.
Hyperpigmentation Forms
Chlosama, Lentigo, Melasma, Nevus, Stain, and Tan.
Chloasma
“Liver spots” Increased pigmentation caused by sun exposure, or other causes. Melasma is a type of chloasma.

Herpes zoster
AKA Shingles. Painful skin condition from reactivation of the chickenpox virus; AKA varicella-zoster virus (VZV) Viral infection of sensory nerves characterized by groups of red blisters that form a rash that occurs in a ring or line. Typically confined to one side of the body. Can cause nerve, and organ damage. Severe pain that can last for months or years. Treated with antiviral drugs.

Tinea Versicolor
Non-contagious, also called pityriasis, vericolor.
Fungal condition that inhibits melanin production. It is caused by yeast a normal part of the human skin. Characterized by white, brown or salmon-colored flaky patches from the yeast on the skin. High humidity and, summer heat stimulate the condition, usually fades in the cold winter season, and recurs in the warm season.
3 Types of skin cancer
Basal Cell Carcinoma, Squamous Cell Carcinoma, Malignant Melanoma.
Basal Cell Carcinoma
Most common and least severe. Characterized by open sores, reddish patches, or smooth growth with elevated border. Often appears shiny bumps that are colored or as light, pearly nodules. Sometimes blood vessels run through the nodules.
Caused by overexposure of UV radiation, can be removed by surgery or other medical procedures.
Squamous Cell Carcinoma
Characterized by red or pink scaly papules or nodules. Sometimes by open sores or crusty areas that do not heal and may bleed easily. Can grow and spread to other parts of the body. More serious than Basal Cell Carcinoma.
Malignant Melanoma
Most serious form of skin cancer. Black or dark patches on the skin are usually uneven in texture, jagged, or raised. Can be tan or white. May appear in pre existing moles. Often found on feet, toes, backs, and legs.
More deadly because it metastasizes throughout the body and to internal organs via lymphatics and blood stream. Many young people can die from this dangerous form of cancer.
Infrequent intense UV exposure may cause a higher risk for this cancer, than chronic continues exposure does.
Cases of Acne
Genetics/Heredity, Clogged follicles, Bacteria, and triggers.
Pilosebaceous Unit
Term for entire follicle. Includes hair shaft, sebaceous gland, and sebaceous duct or canal to the surface.
Retention Hyperkeratosis
Hereditary factor in which dead skin cells build up because they do not shed from the follicles as they do on normal skin. Excessive sebum production can overtax the sebaceous follicles and cause further cell build up. Consequently comedones are formed.
Sebaceous Filaments
Similar to open comedones are mainly small, solidified impactions of oil without the cell matter. These filaments also block the follicle and can cause an acne breakout. They are often found on the nose.
Bacteria
Bacteria in the follicles are anaerobic.
Anaerobic
Cannot live in the presence of oxygen.
Acne Triggers
Hormonal changes, stress, products and certain foods.
Male Hormones also known as Androgen
Stimulate sebaceous glands. High levels of testosterone cause an increase in oil production, which leads to oily skin, and possible acne.
Adult Acne
More common in females. Adrenal glands responding to stress produce extra hormones. They also fluctuate from birth control pills, pregnancy, premenstrual changes, and menopause. All of these can lead to acne inflammation.
Stress
The adrenal gland responds to stress, and secretes adrenaline which helps us cope with stressful events.
Comedogenic
Fatty ingredients such as waxes and some oils can clog or irritate follicles, these products block follicles which cause cell buildup, resulting in comedones.
If client has chin and cheek break outs ask client about?
Diet, also could be sensitive to certain foods. Dairy is common.
Food that can trigger acne
Excessive iodides in salt, MSG, kelp, cheese, processed and packaged foods. Especially fast food. Minerals obtained from an ocean source found in vitamins.
Foods that help those with acne
Fresh vegetables, fruits, and increasing water intake.
Acne Mechanica Breakouts
Pressure or friction from rubbing or touching the face, phone use or hats can contribute to this.
Grades of Acne
Grade I, Grade II, Grade III, Grade IV
Grade I Acne
Minor breakouts, mostly open comedones, some closed comedones, and a few papules.
Grade II Acne
