The Three Main Types of Skin Cancer

Melanoma

Melanoma is the most serious type of skin cancer because it can spread to other
parts of the body if not detected early. It often appears as a brown or black mole
that is changing, irregular in shape, or different from your other
moles.Research shows that approximately 86–93% of melanomas are associated
with UV exposure.

Basal Cell Carcinoma

Basal cell carcinoma is the most common skin cancer. It usually appears as a
small, shiny, flesh colored or pearly bump that may not heal or may bleed easily.
While it rarely spreads to other parts of the body, it can grow deeply and cause
significant tissue damage if left untreated.

Squamous Cell Carcinoma

Squamous cell carcinoma often develops as a firm, red or pink bump or a rough,
crusted spot that doesn’t heal. If not treated promptly, it can become more
aggressive and occasionally spread. Together, about 90% of non-melanoma skin
cancers (basal cell and squamous cell carcinomas) are linked to UV exposure.
This means that protecting your skin from the sun is one of the most important
things you can do to lower your risk.

Why Daily Sunscreen Matters

UV rays reach your skin every day—even when it’s cloudy or you’re simply
driving, walking to your car, or sitting near a window. That’s why sunscreen
shouldn’t be reserved just for beach vacations. It should be part of your daily
skincare routine.

A simple rule to remember is: If the sun can see your skin, protect it with
sunscreen.

Understanding the Two Types of Sunscreen

Physical (Mineral) Sunscreen

Physical sunscreens contain zinc oxide, titanium dioxide, or both as their active
ingredients. Think of a mineral sunscreen like wearing a lightweight jacket. It
sits on the surface of your skin and reflects much of the sun’s UV radiation away
from your skin. It begins working immediately after application, making it an
excellent choice if you’re heading outdoors right
away.
Mineral sunscreens are also a great option for:

• Sensitive skin
• Rosacea
• Children
• Anyone who has reacted to chemical sunscreens

Chemical Sunscreen

Chemical sunscreens contain one or more active ingredients that absorb UV
rays before they can damage your skin. Because they absorb UV energy, some
people notice warmth or flushing after application,particularly those with
sensitive skin or rosacea. These sunscreens should be applied about 30 minutes
before going outdoors to allow time for them to become fully effective.
Occasionally, people may also develop sensitivity to one or more of the
ingredients.

Don’t Forget to Reapply

No sunscreen lasts all day. Whether you choose a mineral or chemical
sunscreen, remember to:

• Apply generously every morning.
• Reapply every two hours when outdoors.
• Reapply after swimming, sweating, or towel drying.

Healthy Skin Starts with Daily Habits

Daily sunscreen use is one of the easiest and most effective ways to protect your
skin from premature aging and reduce your risk of skin cancer. Your skin is
with you for life—protect it every day, rain or shine.
