How Much Sunscreen Should You Use?
Applying the right amount of sunscreen is essential for effective sun protection. Many people don’t apply enough, which reduces its effectiveness and leaves the skin vulnerable to UV damage. Using the correct quantity ensures that your skin is fully protected from harmful UVA and UVB rays.
1. How Much Sunscreen to Use on the Face
For the face alone, dermatologists recommend using:
✔ ½ teaspoon (or about a nickel-sized amount) of sunscreen
✔ Two finger lengths of sunscreen (squeeze a line of sunscreen along the length of two fingers)
π‘ Tip: Don’t forget to cover your ears, neck, and lips (use SPF lip balm)!
2. How Much Sunscreen to Use on the Body
For full-body coverage, use:
✔ 1 ounce (about a shot glass full) of sunscreen
✔ This amount should be evenly applied to cover all exposed areas, including:
- Arms
- Legs
- Back
- Chest
- Shoulders
- Feet
π‘ Tip: If you’re wearing a swimsuit, apply sunscreen 15-20 minutes before sun exposure and reapply every two hours.
3. How Often Should You Reapply Sunscreen?
Sunscreen does not last all day! It must be reapplied regularly to maintain protection.
⏳ Reapply every 2 hours, especially if you're outdoors.
π¦ After swimming or sweating, reapply immediately (even if using waterproof sunscreen).
π¨ If you're indoors but exposed to sunlight through windows, reapply at least once in the afternoon.
π‘ Tip: For convenient touch-ups over makeup, use a powder sunscreen or sunscreen spray!
4. Sunscreen Application Tips for Maximum Protection
✔ Apply 15-20 minutes before going outside to allow full absorption.
✔ Use a broad-spectrum sunscreen with SPF 30 or higher for daily use.
✔ Apply sunscreen even on cloudy days—80% of UV rays still penetrate through clouds.
✔ Don’t forget hidden areas like the back of your hands, feet, ears, and scalp (if hair is thin).
✔ Layer sunscreen with other sun protection measures, such as hats, sunglasses, and protective clothing.
π‘ Tip: Sunscreen should be the last step in your skincare routine before applying makeup!
Final Thoughts
Using the right amount of sunscreen is key to protecting your skin from premature aging, sunburn, and skin cancer. A nickel-sized amount for the face and a shot glass for the body ensures full coverage and maximum protection. Remember to reapply regularly, and make sunscreen a non-negotiable step in your daily routine!
