Your Skin

The Epidermis & Dermis

Epidermis is the outer layer which is made up of dead cells and keratin which makes this outer layer waterproof and tough.

Dermis is the tough and elastic layer which lies below the epidermis. Sebaceous glands keep the skin and hair soft by secreting oil into a hair follicle.

Your Skin Layers

• Regular washing with soap & water.

• Eating a balanced diet.

• Drinking plenty of water.

• Good sleeping habits.

• Avoid the sun & tanning lamps.

Caring for Your Skin

Preventing Skin Damage

Overexposure to ultraviolet (UV) radiation emitted from the sun and tanning lamps causes skin to become leathery, wrinkled, and discolored, and leads to skin cancer.

• Wear sunscreen that blocks UVA and UVB rays (two types of radiation)

• Wear a 15 or higher SPF (sun protection factor) sun screen lotion.

• Never use the tanning lamps.

• Wear a hat with a brim.

• Limit sun exposure.• Wear long sleeves &

pants.• Do not use products

to help you tan.

Melanoma: a deadly form of skin cancer

Treating Acne

Acne forms when excess oil and dead cells plug a hair follicle. Bacteria from the skin’s surface multiplies within the plug and combines with the white blood cells causing the hair follicle to become inflamed and an acne lesion , or pimple, to form.

Hormones, heredity, and stress are some factors that influence acne outbreaks.

Care: Keep your skin clean. Because your fingers and nails carry bacteria, do not scratch or squeeze acne.

Severe acne should be seen by a dermatologist, a doctor who specializes in treating skin problems.

Treating Skin Infections

Several types of microorganisms can infect the skin. Although the majority of these infections are not serious, they can be painful or embarrassing. Boils- painful large bumps caused

by bacteria that infects the hair follicles.

Cold Sores- clusters of watery blisters around the mouth caused by a virus.

Ringworm-fungi infection found in the moist areas of the skin. Requires prescription medication to cure.

Warts- hardened growths of the skin caused by a virus. Over the counter medication can treat warts.
