Transcript Module 20: Skin Diseases and Disorders
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
Process that takes many years
Do not necessarily age as your parents
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
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
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 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
“Aging rays”
90 – 95% rays reach the earth
Rays weaken the collagen and elastin
fibers
Causes wrinkling and sagging in skin
tissues
“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
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
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
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
Dermatitis Venerate – allergies
developed to ingredients in:
Cosmetics
Antiseptics
Cold waving lotions aniline derivative tints
WEAR GLOVES
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
An inflammation of the skin caused by
contact with chemicals or substances
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
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
Keep implements and surfaces clean
and disinfected
Wear gloves
Keep hands clean and moisturized
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
Lesion – is a mark that may indicate an
injury or damage that changes the
structure of tissues or organs
Primary
Secondary
Tertiary
Different color or raised above surface

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

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
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
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
