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

in moles
 Coloration

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



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

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
