Your Skin
A Lesson About Sun Safety
Learning Objectives
At the completion of this program, students
will be able to:
Identify three negative effects of
unprotected, excessive sun exposure
Identify three risk factors for skin cancer
Identify melanoma as the most dangerous
form of skin cancer
Describe three personal behavior changes
that will decrease their risk for skin cancer
The Structure of Your Skin
 The skin is your body’s
largest organ
 It protects you from the
sun and from infections
 The skin has 3 layers:
epidermis, dermis and
subcutis
 Skin color depends on the
activity of the
melanocytes in the
epidermis

UV Radiation
 Many types of rays come from the sun:
Heat rays, visible light, and invisible
ultraviolet light or UV radiation
 Two kinds of UV radiation reach the earth:
UVA rays – longer rays, penetrate skin deeply,
and cause wrinkling and tanning
UVB rays – shorter rays which cause burning
of the skin
Tanning and burning of the skin are signs of
skin damage!
The Dangers of UV Radiation
Overexposure to UV Radiation causes:
Sunburn
DNA Damage
Skin Cancer
Premature aging (wrinkles)
Cataracts
Immune system depression
Skin Cancer Facts
Skin cancer is the most common cancer but
also the most preventable
Childhood sunburn is the most common
cause of skin cancer
More than 3,000,000 skin cancer cases are
diagnosed in the US each year
One in every two cancers is skin cancer
One in every five Americans will develop
skin cancer in their lifetime
What Causes Skin Cancer?
UV radiation causes increased activity in
the melanocytes
This increased activity is the cause of
freckles, tanned skin and sunburns
Sometimes this leads to changes in cell
structure and function, causing cancer
Do You Know the Three Main
Types of Skin Cancer?
 Basal Cell Carcinoma
75% of all skin cancers
 Squamous Cell Carcinoma
20% of all skin cancers
 Melanoma
5% of all skin cancers but
responsible for 75% of skin
cancer deaths
Signs of Melanoma
What are the ABCD’s?
 Asymmetry
 Border
 Color
 Diameter
 CHANGE!
Who is at Risk for Skin Cancer?
Fair skin, burns
easily
Light hair color
Blue or green eyes
Freckles
Many moles
Family history of
skin cancer
When is UV Radiation
Most Intense?
 In the middle of the day
(Between 10 a.m. and 4 p.m.)
 During the summer months
 At higher altitudes
 In regions of the earth closer to the equator
Use the UV Index as a tool to help plan
your outdoor activities.
Protective Measures
 Avoid midday sun
 Cover up with hats,
clothing and sunglasses
 Use sunscreen
 Apply liberally and often
 Avoid reflective surfaces
 Seek shade when your
shadow is shorter than
you are
 Avoid tanning beds
Tanning Beds are NOT Safe!
 Studies show tanning beds are linked





to skin cancer and premature aging
Indoor tanning lamps emit UVA and
UVB radiation at levels that can be as
much as 15 times stronger than the sun
Minors (under the age of 18) must
have in-person, written parental
consent before using a commercial
tanning facility
If you must be tan, use a self tanner
You still must use sunscreen
Remember:
There is no such thing as safe tan!
