When it comes to protecting your skin, sunscreen is your best defense against the harmful effects of the sun.
At Upstate Medical University, our dermatology department is committed to educating patients about skin health and prevention strategies to maintain a healthy, radiant complexion.
This comprehensive guide will provide you with essential information on why sunscreen is necessary, how it protects you, and how to choose and use it properly.
Why Sunscreen is Necessary
The Effects of UV Radiation
Exposure to ultraviolet (UV) radiation from the sun can cause severe damage to the skin. The two main types of UV rays are:
- UVA Rays: These penetrate deep into the skin’s layers, leading to premature aging, wrinkles, and some types of skin cancer.
- UVB Rays: These affect the outer layer of the skin and are the primary cause of sunburn, which can also lead to skin cancer.
The Risks of Sun Exposure
Regular exposure to UV radiation can result in:
- Sunburns
- Premature aging (wrinkles, leathery skin)
- Hyperpigmentation and sunspots
- Increased risk of skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma
According to the Skin Cancer Foundation, about 90 percent of nonmelanoma skin cancers are associated with exposure to UV radiation from the sun. The most common form of skin cancer is basal cell carcinoma (BCC). It is estimated that there are 3.6 million BCC cases diagnosed in the United States each year.
How Sunscreen Protects You
The Science Behind Sunscreen
Sunscreen contains active ingredients that work to protect your skin by:
- Reflecting UV Rays: Ingredients like zinc oxide and titanium dioxide sit on the skin’s surface and physically block and reflect UV rays.
- Absorbing UV Rays: Chemical sunscreens contain ingredients like avobenzone and octanoate, which absorb UV radiation and release it as heat.
SPF Explained
SPF (Sun Protection Factor) measures the effectiveness of a sunscreen in protecting your skin from UV rays. A higher SPF provides more protection, but it is crucial to apply it correctly and reapply it throughout the day.
How to Choose the Right Sunscreen
Types of Sunscreens
- Physical (Mineral) Sunscreens: Contain zinc oxide or titanium dioxide and are ideal for sensitive skin.
- Chemical Sunscreens: These have organic compounds that absorb UV radiation. They tend to be more water-resistant and less likely to leave a white residue.
Key Features to Look For
- Broad Spectrum: Protects against both UVA and UVB rays.
- SPF 30 or Higher: Provides adequate protection for most people.
- Water-Resistant: Important for outdoor activities and swimming.
- Suitable for Your Skin Type: Choose formulations that match your skin’s needs (e.g., oil-free for oily skin, hydrating for dry skin).
How to Use Sunscreen Properly
Application Tips
- Apply Generously: Use about a shot glass full (1 ounce) for full-body coverage.
- Reapply Frequently: At least every two hours, and immediately after swimming or sweating.
- Don’t Forget Key Areas: Ears, neck, hands, feet, and the part in your hair are often missed.
Daily Use
Even on cloudy days or when indoors near windows, UV rays can still affect your skin. Integrating sunscreen into your daily routine is essential for consistent protection.
Why Proper Sunscreen Use is Important
Proper sunscreen use can significantly reduce the risk of developing skin cancer, prevent premature aging and maintain an even skin tone. By making sunscreen a part of your daily routine, you are investing in your long-term skin health.
