Module 8 – 12’: Skin Diseases and Disorders

Introduction Skin care begins with understanding its

underlying structure and basic needs You must recognize adverse conditions

Inflamed skin Diseases Infectious skin disorders

Skin care specialists are in high demand High end salons/spas Work less arduous and physically

demanding

Aging of the Skin Process that takes many years Do not necessarily age as your parents

Intrinsic Factors Genetic aging

How your parents aged Their skin coloring Resistance to sun damage

Gravity

Facial expressions Repeated movements – expression lines Crow’s feet – eyes Nasolabial folds – corners of the nose Scowl lines – between eyes

Extrinsic Factors Primarily environmental factors Up to 85% of skin aging What we choose to put into our bodies

has a profound effect on the over all aging process

Sun Exposure Tanning= no-no Daily doses – damaging causing # 1 cause of premature aging Use broad spectrum sunscreen every day –

(most makeup has)

Smoking Free Radicals – unstable molecules that cause

biochemical aging Causes premature wrinkling of the skin Weakening and contractions of the blood

vessels and small capillaries Tissues are deprived of essential oxygen Skin may have a yellow or gray tone to it

and a dullness

Alcohol Causes body to repair itself poorly Interferes with proper nutrition distribution

for skin & body tissues Over dilates the blood vessels and

capillaries Causes capillaries to weaken and burst Flushed appearance and blotchy red eyes Dehydrates the skin by drawing out

essential water Causing the skin to appear dull and dry

Smoking & Alcohol Combination can be devastating to the

skin Constant dilation and contraction of

capillaries and blood vessels as well as oxygen and water deprivation quickly make skin appear lifeless and dull

Difficult for skin to adjust and repair itself

Illegal drug use Similar effects of smoking Interfere with body’s intake of oxygen –

affecting healthy cell growth Some can aggravate skin conditions – acne Dryness and allergic reactions on skin

surface

Cumulative stress – Causes biochemical changes that lead to

tissue damage Poor nutrition – deprives skin of

proteins, fats, carbohydrates, vitamins, minerals needed

Exposure to pollution – produces free radicals and interferes with oxygen consumption

Outside factors that influence aging Sun Environment Health habits General lifestyle

Heredity has little to do with the aging process when above factors are so great (15%)

The Sun and its Effects The sun and its UV rays have the

greatest impact 80 – 85 % of our aging process is

caused by the rays Collagen and elastin fibers weaken as

we age Happens faster when skin is frequently

exposed

UVA Rays “Aging rays” 90 – 95% rays reach the earth Rays weaken the collagen and elastin

fibers Causes wrinkling and sagging in skin

tissues

UVB Rays “Burning” rays Affects the melanocytes

Rays can destroy melanocytes cells so they can no longer protect the skin

Do not penetrate as deep as UVA rays Can be equally damaging to the skin and

eyes UVB rays do contribute to the body’s

absorption of vitamin D

UVB rays - cause Sunburns Tanning Majority of skin cancers Shorter rays that penetrate at the base of

epidermis

Precautions Sunscreen of SPF 15 or higher Avoid exposure during peak hours (10

am – 3 pm) Apply sunscreen 30 minutes before

exposure to allow for absorption Reapply sunscreen after water activity

and sweating Sunscreen should be full or broad

spectrum to filter both UVA & UVB rays – check expiration dates

Avoid exposure for children under 6 months

Wear protective clothing See Dermatologist regularly if changes

in moles Coloration Size shape

Self-care examinations

Skin Aging and the Environment Air pollutants affect the overall

appearance and health Factories Auto exhaust Secondhand smoke Speeds up the aging process

Follow daily skin routine Washing Exfoliating - Removes dead skin cells Moisturizers Protective lotions Foundation

Disorders of the Skin Objective symptoms

Symptoms that can be seen Subjective symptoms

Symptoms that are those that can be felt Prognosis

Foretelling of probable course of a disease Diagnosis

Recognition of a disease by its symptoms

Occupational Disorders on Cosmetology Dermatitis Venerate – allergies

developed to ingredients in: Cosmetics Antiseptics Cold waving lotions aniline derivative tints

WEAR GLOVES !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Contact Dermatitis An inflammation of the skin caused by

contact with chemicals or substances

Allergic Contact Dermatitis Develops an allergy to an ingredients or

a chemical by repeated skin contact Sensitization –

An allergic reaction created by repeated exposure to a chemical or substance

Fingers Face scalp

Irritant Contact Dermatitis When irritating substances temporarily

damage the epidermis Not usually chronic if precautions are

taken Corrosive substances or exfoliants

Inflammation, redness, swelling , itching, burning

WEAR GLOVES!!!!! Or use tongs!!!!!! Hand washing causes dryness and

cracking – use moisturizers

Protect Yourself Keep implements and surfaces clean

and disinfected Wear gloves Keep hands clean and moisturized

Disorders of the Skin You must be prepared to recognize

certain skin conditions Know what you can and cannot work on If you see a skin condition you do not

recognize – refer to a physician DO NOT serve a client who has an

inflamed skin disorder

Lesions of the Skin Lesion – is a mark that may indicate an

injury or damage that changes the structure of tissues or organs Primary Secondary Tertiary

Primary Lesions Different color or raised above surface Bulla – A large blister containing a

watery fluid Cyst – A closed, abnormally developed

sac, containing fluid, semifluid or morbid matter

Primary Lesions Continued Macule – A spot or discoloration on the

skin – freckle Nodule – a solid lump larger than .4

inches, can be easily felt Papule – A pimple, contains no fluid but

may develop pus

Primary Lesions Continued Pustule – An inflamed pimple containing

pus Tubercle – An abnormal rounded, solid

lump

Primary Lesions Continued Tumor – A swelling; an abnormal cell

mass resulting from excessive multiplication of cells, varies in size, shape and color

Vesicle – A small blister or sac containing clear fluid – Ex: poison ivy , poison oak

Primary Lesions Continued Wheal – An itchy swollen lesion that

lasts only a few hours Ex: insect bite, urticaria (skin allergy),

hives, mosquito bite

Secondary Lesion Those that develop in the later stages

of disease: Crust - Dead cells that form over a

wound or blemish while it is healing Ex: scab on a sore

and turn black

Closed Comedo Milia – Whiteheads Should be removed under sterile

conditions using proper extraction procedures

Psoriasis – A skin disease characterized by: red patches, covered with

white-silver scales usually found on the scalp elbows, knees,

chest and lower back It is not contagious Caused by cells turning over faster than

normal Irritated – bleeding can occur Not curable

Pigmentations of the Skin Albinism – Congenital

leukoderma/hypopigmentation or absence of melanin pigment of the body Silky hair is white Skin is pinkish white and will not tan Eyes are pink Skin is sensitive to light and ages early

Absence of pigment Results in white or light splotches

Chloasma – increased pigmentation on the skin (not elevated) Also called moth patches or liver spots Cumulative sun exposure exfoliation

Lentigines – singular: Lentigo – Technical term for freckles developed by exposure to sunlight and air

Leukoderma – light abnormal patches Caused by: burn or congenital disease that

destroys pigment producing cells Classified as : Vitiligo and albinism

Nevus – birthmark Stain – Abnormal brown or wine-colored

skin discoloration with a circular and irregular shape – cause is unknown

Tan – Change in pigmentation of skin caused by exposure to the sun or ultraviolet rays

Vitiligo – Milky-white spots – Causes hypopigmented spots and blotches must be protected from overexposure to the

sun (Michael Jackson claimed to have this)

Hypertrophies of the Skin Keratoma – An acquired superficial growth

of the skin – many are benign or harmless Callus Corn – inward growth

the skin, that may appear uneven in texture, jagged or raised

Most commonly located on areas of the body not receiving regular sun exposure

Least common, but most serious• Important for cosmetologists to be able to

recognize the appearance of serious disorders to better serve clients

• Cosmetologist should not attempt to diagnose a skin disorder, but should sensitively suggest the client seek medical advise from a dermatologist

Acne & Problem Skin Most people have skin care issues at

some point in their lives Acne is both a disorder an esthetics

issue

Acne is a disorder affected by 2 major factors Heredity hormones

Retention Hyperkeratosis Heredity tendency for acne-prone skin to

retain dead skin cells in the follicle Forming an obstruction Exacerbates inflammatory acne lesions Papules & Pustules

Skin oiliness is heredity Propionibacterium acnes are anaerobic

Bacteria that cannot survive in the presence oxygen

Main food source is fatty acids found in sebum

Bacteria flourish in clogged follicle No oxygen Plenty of food (sebum)

Bacteria multiply Causing inflammation and swelling Eventually rupture

Immune system is altered Blood rushes to ruptured follicle with

white blood cells to fight bacteria Causes redness in pimples

Acne pustule is an inflammatory lesion resulting from wall rupture and infusion of blood

Pustule forms from papule when enough white blood cells form pus

Dead white blood cells

Acne Treatment Use cleaners formulated for oily skin Follicle exfoliants - leave-on products to

remove cell buildup Allows oxygen in to kill bacteria

Avoid products that contain fatty materials Noncomedogenic – designed and proven to

not clog pores/follicles

Do not use harsh products – can cause inflammation and worsen condition

Trained salon and spa professionals can work over mild to moderate cases of acne – specialized education

Definitions Pertaining to Plastic Surgery Rhytidectomy – face lift Blepharoplasty – Eyelid surgery Chemical Peeling – Specially formulated

chemical solution is applied to the areas to be treated A technique for improving the appearance when

wrinkles of the skin are present. The chemical causes a mild, controlled burn of

the skin

Rhinoplasty – Plastic surgery of the nose

Mentoplasty – Chin surgery Dermabrasion – A technique to smooth

scared skin by “sanding” irregularities Performed with a rotary abrasive instrument

that thins the skin, making the sharp edges of facial scars less prominent

Micro-dermabrasion – uses a diamond bit to “sand” off skin – “for younger looking skin”

Injectable fillers – tiny injections of collagen may used to raise depressions closer to normal skin level Used for deep scars, acne scaring, deep

aging lines around the mouth or forehead

Ex: Botox
