Imagine this: You’re getting ready for a fun day outdoors—maybe you’re taking the kids to the playground or the amusement parks, heading out for a morning jog, or meeting friends for a game of pickleball. You grab your sunscreen, give yourself a quick swipe or spritz, and feel good to go. But are you applying enough to stay protected? Most people don’t apply nearly as much sunscreen as they should, leaving their skin vulnerable to sunburn, premature aging, and an increased risk of skin cancer.

So, how much sunscreen should you really be using? And what’s the best way to make sure you’re actually covered? Let’s get into the details.

Why the Right Amount of Sunscreen Matters

Applying too little sunscreen significantly reduces its effectiveness. Even if you're using a high SPF, not applying enough means you’re not getting the full protection your sunscreen is designed to provide.

The American Academy of Dermatology (AAD) recommends using about one ounce of sunscreen—roughly the size of a shot glass—to cover your entire body. However, most people only apply half this amount, leaving their skin more exposed than they realize. And even when applied correctly, sunscreen’s protection doesn’t last indefinitely—it requires frequent reapplication to maintain its effectiveness.

Why Sunscreen Alone is a Time-Consuming Solution

Sunscreen isn’t just about how much you use—it’s also about when and how often you apply it. To get full protection, you need to apply it at least 15 minutes before going outside, giving it time to absorb and form a protective barrier. But that’s just the start. Sunscreen wears off due to sweat, water, and natural breakdown, meaning you need to reapply every two hours to stay protected.

Let’s be honest—keeping up with this routine, especially for kids, can feel like a hassle. That’s where UPF clothing becomes a practical and comfortable alternative. Unlike sunscreen, which fades over time, UPF apparel provides continuous UV protection the moment you put it on. No waiting, no reapplying—just effortless sun safety for busy individuals and families alike.

How Much Sunscreen Should You Use?

To make sure your skin is properly covered, follow these general guidelines for sunscreen application based on body parts. Use the teaspoon method or finger-length rule to help you visualize the right amount:

Face and Neck: Use half to one teaspoon (or two to three finger lengths) for full coverage. Don’t forget your ears and the back of your neck, which are often overlooked.
Arms: Apply half a teaspoon per arm (or two finger lengths) to ensure full protection.
Legs: Each leg needs about one teaspoon (or three finger lengths) to cover all exposed skin, including the tops of your feet.
Torso: Use one teaspoon for the front and one teaspoon for the back of your torso (about three finger lengths per side).
Lips: Use a lip balm with SPF 30+, as lips are prone to sunburn and often forgotten. Reapply frequently since lip sunscreen wears off quickly.
Full Body: Use one ounce of sunscreen—about the size of a shot glass—to cover your entire body.

If applying and reapplying that much sunscreen sounds like a hassle, UPF clothing is a simple, long-lasting alternative that offers reliable sun protection without the need for frequent touch-ups.

Reapplying Sunscreen: How Often is Enough?

Applying sunscreen once in the morning isn’t enough to keep you protected all day. Sunscreen wears off with time, sweat, and water exposure, so regular reapplication is crucial.

Every Two Hours: No matter what, reapply every two hours when you’re outside—even on cloudy days or during winter months.
After Swimming or Sweating: Water-resistant sunscreen still needs to be reapplied immediately after drying off.
After Towel Drying: Wiping off with a towel removes sunscreen, so reapply right after drying off from swimming, showering, or sweating.

Why UPF Clothing is a Practical Alternative

Did you know that wearing a single Essuntials UPF 50+ shirt can save you at least eight bottles of sunscreen over time? Applying and reapplying sunscreen across your entire body is time-consuming, costly, and often impractical. UPF clothing offers a reliable, all-day solution, reducing the need for sunscreen while keeping your skin protected.

If constant sunscreen application feels like a hassle—especially if you're managing a busy day or chasing after kids—UPF clothing makes sun protection effortless while providing superior effectiveness.

Long-lasting UV protection: UPF 50+ clothing, like from Essuntials, is designed to last for at least 40 washes while maintaining its protective qualities, ensuring consistent sun safety over time.
No more constant reapplication: UPF apparel offers all-day broad spectrum protection that won’t fade from sweat, swimming, or everyday movement, eliminating the need to reapply like sunscreen.
Comfortable & stylish: Modern UPF clothing is breathable, lightweight, and easy to wear, making sun protection a seamless part of your daily routine.

By covering your arms, torso, and legs with UPF apparel, you reduce your sunscreen use while ensuring continuous protection. SPF and UPF work best together—use sunscreen on exposed areas like your face, neck, and hands, and rely on UPF clothing to cover the rest.

Sunscreen Tips for Hard-to-Reach Areas

Some parts of the body are trickier to cover with sunscreen, but leaving them unprotected can lead to painful burns. Here’s how to ensure full coverage:

Use a Spray Sunscreen: A spray sunscreen can be helpful for areas like your back, but make sure to rub it in after application for even coverage.
Ask for Help: If you’re with friends or family, have someone help apply sunscreen to hard-to-reach spots.

Commonly Missed Spots You Shouldn’t Forget

Certain areas of the body are frequently forgotten, leading to unexpected sunburns. Make sure to apply sunscreen to:

Ears
Back of the neck
Tops of the feet and toes
Scalp (if you have thinning hair or a part)
Backs of the hands

Using Sunscreen with Makeup

If you wear makeup, you still need sunscreen underneath it for full protection. Here’s how to layer sunscreen with your cosmetics:

Apply Sunscreen First: Sunscreen should always be the base layer on clean, dry skin before applying any makeup products.
Use Makeup with SPF: While not a replacement for sunscreen, foundations, powders, and primers with SPF can provide an added layer of protection.
Reapply with SPF Powders, Setting Sprays, or Sunscreen Sticks: To avoid disturbing your makeup, use an SPF powder, setting spray, or stick for reapplication throughout the day.

The Bottom Line: SPF Requires More Than You Think

Most people don’t apply enough sunscreen, which means they’re not getting the protection they need. That leaves their skin vulnerable to sunburns, premature aging, and long-term damage. When in doubt, apply generously. Stick to the shot glass rule for your entire body and the two-to-three finger lengths rule for your face, neck, and arms.

However, applying and reapplying sunscreen to your entire body every two hours isn’t always practical. That’s why UPF clothing is essential—it allows you to stay protected without the hassle of constant reapplication.

Whether you’re keeping up with kids at the playground, heading out for a long walk, or just running daily errands, combining sunscreen and UPF clothing is the easiest way to simplify sun protection and ensure complete coverage. Start protecting your skin today, because sun damage adds up over time!

Live well under the sun!
