Stay Sun-Smart: How to Choose and Use Sunscreen

You can make great memories outdoors — whether you’re at the beach, exploring a park, or enjoying a neighborhood festival. But protecting your skin from harmful UV rays is essential to ensure many more great memories — by reducing your risk of skin cancer and keeping your skin healthy for years to come.

Sun safety isn’t just about using sunscreen — it’s about using it correctly. You may not be applying enough, missing key areas, or choosing products that don’t match your needs. Here’s how to get the most out of your sun protection routine.

Not All Sunscreens Are The Same

Understanding the different types of sunscreens can help you choose what works best for your skin and lifestyle.

Chemical Sunscreens

These absorb UV rays and convert them into heat, which is then released from the skin.

  • Lightweight and easy to rub in
  • Often preferred for daily use or under makeup
  • Can be more water-resistant
  • May cause irritation for sensitive skin

Mineral (Physical) Sunscreens

These sit on top of the skin and reflect UV rays. Common ingredients include zinc oxide and titanium dioxide.

  • Start working immediately after application
  • Less likely to irritate sensitive or acne-prone skin
  • May leave a slight white cast
  • Need to be reapplied more often if sweating or swimming

Broad-Spectrum Protection

No matter which type you choose, look for “broad-spectrum” on the label. This means the sunscreen protects against both:

  • UVA rays, which cause premature aging
  • UVB rays, which cause sunburn and contribute to skin cancer

Choose a sunscreen with an SPF of 30 or higher for effective protection. SPF stands for “sun protection factor” and measures how well sunscreen protects skin from UVB rays. An SPF of 30 blocks 97% of harmful UV rays; an SPF of 50 blocks 98%. But no sunscreen can block 100%, which is why it’s so important to limit exposure and reapply as directed.

Are You Applying Enough? Probably Not

One of the most common mistakes is simply not using enough sunscreen.

  • Adults typically need about one ounce (a shot glass full) to cover their entire body
  • Apply sunscreen 15 minutes before going outside (for chemical formulas)
  • Reapply every two hours, or more often if swimming or sweating

Sunscreen is not just for beach days! UV rays can affect your skin even on cloudy days and during everyday activities like walking or driving.

The Most Commonly Missed Spots

Even diligent sunscreen users often miss areas that are highly vulnerable to sun damage. Be sure to cover:

  • Tops of the ears and the rim of the ear
  • Back of the neck
  • Scalp (especially along parts or thinning hair)
  • Tops of the feet and between toes
  • Backs of the hands
  • Lips (use an SPF lip balm)
  • Around the eyes (use sunscreen-safe formulas or sunglasses for added protection)

These areas are frequently exposed and are common sites for skin cancer.

Choosing The Right Sunscreen For You

The “best” sunscreen is the one you’ll actually use every day! Consider:

  • Your skin type: Sensitive skin may benefit from mineral formulas
  • Your activities: Choose water-resistant sunscreen if swimming or sweating
  • Ease of use: Lotions, sprays, and sticks all work — just be sure to apply evenly and thoroughly

 If you’re using a spray sunscreen, spray generously and rub it in to ensure full coverage.

Other Sun-Safe Habits

Sunscreen works best when combined with other sun-safe habits. Remember to:

  • Seek shade during peak sun hours (10 a.m. to 4 p.m.)
  • Wear protective clothing, hats, and sunglasses
  • Avoid tanning beds

Together, these steps provide the strongest defense against harmful UV exposure.

Protect Your Skin Year-Round

Sun protection isn’t just for summer — it’s a year-round commitment. Making sunscreen part of your daily routine, along with regular skin checks, can help catch potential issues early and keep your skin healthy.

With a little extra attention to how and where you apply sunscreen, you can enjoy everything Delaware has to offer — safely and confidently.
