Book AppointmentSummer sun means more time outdoors, and more exposure to UV rays that can cause sunburn, premature aging, and long-term skin damage. A few consistent habits, protective clothing, the right sunscreen, and smart timing, make a real difference in keeping skin healthy through the season.
Sun Protection Basics
Wear protective clothing such as wide-brimmed hats and long-sleeve shirts, apply broad-spectrum sunscreen with SPF 30 or higher 15 to 30 minutes before going outside, and reapply every two hours. Avoid peak sun hours, generally 10 a.m. to 4 p.m., when UV radiation is strongest, and wear UV-blocking sunglasses for eye protection.
Choosing the Right Sunscreen
Look for broad-spectrum formulas with an SPF of 30 or higher. These protect against both UVA and UVB rays, which lowers the risk of skin cancer and sun-related skin aging.
Understanding SPF
- SPF 30 blocks about 97% of UVB rays.
- SPF 50 blocks about 98%.
- No sunscreen blocks 100% of UV rays, so reapplication and full coverage matter as much as the SPF number itself.
Applying Sunscreen Effectively
- Apply 15 to 30 minutes before sun exposure.
- Use about one ounce for full-body coverage.
- Don’t skip commonly missed spots: ears, back of the neck, and tops of feet.
- Reapply every two hours, and more often after swimming or sweating.
Protective Clothing
- Long sleeves, breathable pants, and loose-fitting skirts all help reduce UV exposure.
- Tightly woven fabrics like polyester, nylon, and spandex block more UV than loosely woven cotton.
- UPF-rated clothing (ultraviolet protection factor) with a rating of 30 or higher offers strong protection: UPF 50 allows only about 2% of UV rays through, versus about 3.3% for UPF 30.
Sun Protection Accessories
Wide-brimmed hats with at least a 3-inch brim and a UPF rating of 30 or higher help shield the face. Darker colors and tightly woven fabrics offer the best defense.
Sunglasses should block 99 to 100% of UVA/UVB rays and carry a UV400 rating. Wrap-around styles add extra protection around the eyes.
UV-protective umbrellas block a large share of direct sunlight and provide useful shade during outdoor activities, even on overcast days.
Timing Outdoor Activities
UV rays peak between 10 a.m. and 4 p.m. Limiting outdoor activity during this window, or adding extra protection when it can’t be avoided, reduces the risk of sunburn and cumulative skin damage. Checking the daily UV index is a simple way to plan ahead.
A Skincare Routine That Supports Sun Protection
Morning: cleanse with a gentle cleanser, apply a vitamin C serum for added protection and brightening, then finish with a broad-spectrum SPF 30+ sunscreen.
Evening: cleanse thoroughly to remove sunscreen and pollutants, apply a moisturizer with antioxidants, and consider niacinamide to help calm sun-related inflammation.
Staying Hydrated
Hydration supports skin elasticity and helps prevent dryness during hot summer months. Water-rich foods like watermelon, cucumber, oranges, and strawberries help, as can facial mists with aloe vera or hyaluronic acid for a quick moisture boost.
The Takeaway
Layering habits, protective clothing, broad-spectrum sunscreen, and sun-safe accessories, along with consistent reapplication and avoiding peak sun hours, is the most effective way to limit UV damage over time. Anyone noticing a new or changing spot, or overdue for a routine skin cancer screening should have it evaluated.
