Understanding Sunscreen Basics
What is Sunscreen?
Sunscreen is a topical product designed to protect your skin from the sun’s ultraviolet (UV) rays. It comes in various forms, including creams, sprays, gels, and sticks. The primary purpose is to prevent sunburn and reduce the risk of skin cancer by blocking or absorbing UV radiation.
SPF Explained
SPF, or Sun Protection Factor, measures how well a sunscreen protects your skin from UVB rays, which cause sunburn. For example, if you usually burn after 10 minutes in the sun, SPF 30 theoretically allows you to stay out for 300 minutes (10 x 30) before burning. Keep in mind that no sunscreen offers 100% protection, so reapplication is essential.
Broad-Spectrum Protection
When choosing sunscreen, look for “broad-spectrum” on the label. This means the product protects against both UVA and UVB rays. UVA rays penetrate deeper into the skin and contribute to aging, while UVB rays are responsible for sunburn. A broad-spectrum sunscreen ensures you’re protected from both types of UV radiation.

Why Timing Matters
Sunscreen needs time to bind to your skin and provide full protection. Applying it just before you go outside won’t give you the maximum benefit. Ideally, sunscreen should be applied about 15 to 30 minutes before sun exposure.
How Much Sunscreen to Use
The American Academy of Dermatology recommends using about one ounce (approximately a shot glass full) of sunscreen for the entire body. This might seem like a lot, but it’s crucial for achieving the level of protection stated on the label.
Application Frequency
Sunscreen should be reapplied every two hours, or more often if you’re swimming, sweating, or towel-drying. Even water-resistant sunscreens can lose effectiveness over time.
How to Apply Sunscreen: A Step-by-Step Guide
☑️ Choose the Right Sunscreen: Pick a broad-spectrum sunscreen with an SPF of at least 30. For water activities, select a water-resistant formula.
☑️ Apply Generously: Use about one ounce of sunscreen for your body. Don’t skimp—apply a thick, even layer to all exposed skin.
☑️ Cover All Areas: Pay attention to often-missed spots like the ears, back of the neck, feet, and behind the knees. Don’t forget areas like your scalp if it’s exposed.
☑️ Apply Before Sun Exposure: Put sunscreen on about 15 to 30 minutes before heading outside to ensure it has time to absorb and form a protective barrier.
☑️ Reapply Regularly: Reapply every two hours, or immediately after swimming or sweating. Use a timer or set reminders to stay on track.
☑️ Use Additional Protection: Complement sunscreen with protective clothing, hats, and sunglasses. Seek shade whenever possible, especially during peak sun hours (10 a.m. to 4 p.m.).
Mistakes vs Tips for Effective Sunscreen Application
| Mistake | What Happens | Expert Tip |
|---|---|---|
| Applying Too Little | Insufficient coverage leads to sunburn | Use about one ounce for full body coverage |
| Forgetting to Reapply | Sunscreen wears off, increasing risk | Reapply every two hours or after swimming |
| Using Expired Sunscreen | Reduced effectiveness, higher risk of sunburn | Check expiration dates and replace as needed |
| Applying Sunscreen Only Once | Protection wears off over time | Reapply regularly for consistent protection |
| Ignoring Sensitive Areas | Increased risk of burns on vulnerable spots | Apply to all exposed areas, including ears and feet |
| Skipping Sunscreen on Cloudy Days | UV rays can penetrate clouds | Apply sunscreen regardless of weather |

If your makeup has SPF, it’s a great addition but should not replace your regular sunscreen. Consider using a powder or spray sunscreen for easy reapplication over makeup.
Is there a difference between sunscreen and sunblock?
“Sunscreen” generally refers to products that absorb UV rays, while “sunblock” refers to physical blockers like zinc oxide and titanium dioxide that sit on top of the skin and block UV rays. Many products are labeled as “sunscreen” but function as both.
