Best Sunscreen Practices for Summer: Your Skin’s Survival Guide

Summer is just around the corner, and with it comes the joy of beach days, picnics, and outdoor adventures. But let’s not forget the essential part of summer fun: sunscreen. As a cosmetic dentist and someone deeply passionate about aesthetic medicine, I’ve seen firsthand how neglecting sun protection can lead to premature aging and skin damage. So, let’s dive into the best sunscreen practices for summer to keep your skin healthy and radiant.

I remember my first summer in Istanbul after relocating from the Bay Area. The vibrant culture and sunny days were a dream, but the intense sun was a wake-up call. My skin, accustomed to the foggy mornings of San Francisco, needed a serious upgrade in sun protection. That’s when I started digging deep into the world of sunscreens and best practices.

Whether you’re planning a trip to the beach or just enjoying a walk in the park, understanding the right sunscreen practices can make a world of difference. So, let’s get into it.

Understanding Sunscreen: The Basics

What is SPF and Why Does It Matter?

SPF (Sun Protection Factor) is a measure of how well a sunscreen will protect your skin from UVB rays, the kind that cause sunburn and contribute to skin cancer. But here’s the thing: SPF only indicates protection against UVB rays, not UVA rays, which penetrate deeper into the skin and cause aging and wrinkles. So, you need a sunscreen that offers broad-spectrum protection, covering both UVA and UVB rays.

Choosing the Right SPF

The general recommendation is to use a sunscreen with at least SPF 30. But is higher always better? Let’s consider this: SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. The difference is minimal, but if you have very fair skin or a history of skin cancer, you might want to opt for SPF 50. Personally, I use SPF 30 for everyday activities and SPF 50 for intense sun exposure, like a day at the beach.

Chemical vs. Physical Sunscreens

Sunscreens come in two main types: chemical and physical. Chemical sunscreens work by absorbing UV rays, while physical sunscreens act as a barrier, reflecting UV rays away from the skin. Physical sunscreens, often containing zinc oxide or titanium dioxide, are generally considered safer and more gentle on the skin. They’re also less likely to irritate sensitive skin. However, they can leave a white cast, especially on darker skin tones.

Chemical sunscreens, on the other hand, are usually lighter and easier to apply. But they can be more irritating and may not be suitable for those with sensitive skin. Plus, some chemical filters like oxybenzone have been linked to hormone disruption and environmental concerns. Is this the best approach? Let’s consider the pros and cons before making a decision.

Applying Sunscreen Correctly

Applying sunscreen might seem straightforward, but there’s a bit of a technique to it. You should apply sunscreen about 15-30 minutes before going outside to give it time to absorb into your skin. Use about an ounce (a shot glass full) to cover your entire body. Don’t forget often-missed spots like your ears, the back of your neck, and the tops of your feet.

Reapplication is key. Sunscreen should be reapplied every two hours, or more frequently if you’re swimming or sweating. I’m torn between setting a timer on my phone or just winging it, but ultimately, I think a timer is the way to go. It’s too easy to lose track of time when you’re having fun in the sun.

Sunscreen and Makeup

For those who wear makeup, incorporating sunscreen into your routine can be a bit tricky. Some sunscreens can pill under makeup or leave a white cast. My advice? Look for a lightweight, non-comedogenic sunscreen that won’t clog your pores. Apply it as the last step in your skincare routine, before your makeup. Maybe I should clarify that you can also find makeup products with built-in SPF, but they shouldn’t replace your dedicated sunscreen.

Sunscreen for Kids

Protecting kids from the sun is crucial. Their skin is more sensitive and susceptible to sun damage. Look for mineral-based sunscreens that are gentle on young skin. Apply sunscreen generously and frequently, and don’t forget to protect their eyes with sunglasses and their heads with hats. I always recommend keeping infants under 6 months out of direct sunlight as much as possible.

Sunscreen and Water Activities

If you’re planning on swimming or engaging in water activities, opt for a water-resistant sunscreen. But remember, water-resistant doesn’t mean waterproof. You still need to reapply frequently, especially after toweling off. I usually apply sunscreen before putting on my swimsuit to ensure I don’t miss any spots.

Sunscreen and Different Skin Types

Different skin types have different needs when it comes to sunscreen. If you have oily or acne-prone skin, look for lightweight, gel-based sunscreens that won’t clog your pores. For dry skin, cream-based sunscreens can provide much-needed moisture. And for sensitive skin, mineral-based sunscreens are usually the best bet.

I’ve had patients ask about sunscreen for those with darker skin tones. The struggle with a white cast is real. Look for tinted sunscreens or those with a sheer finish. Brands are getting better at formulating sunscreens that work for all skin tones, so do your research and find one that works for you.

Sunscreen and Clothing

While sunscreen is essential, it’s not the only line of defense against the sun. UPF (Ultraviolet Protection Factor) clothing can provide additional protection. Look for clothing with a UPF rating of at least 30. Hats, sunglasses, and seeking shade during peak sun hours are also crucial.

Beyond Sunscreen: Other Sun Protection Measures

Sunscreen is just one part of a comprehensive sun protection strategy. Wearing protective clothing, seeking shade, and avoiding peak sun hours are all important. And don’t forget about your eyesUV rays can cause cataracts and other eye issues. Wear sunglasses with UV protection to keep your eyes safe.

Staying hydrated is also crucial. The sun can dehydrate you quickly, so make sure to drink plenty of water throughout the day. I always carry a reusable water bottle with me during the summer months.

Common Sunscreen Mistakes to Avoid

Even with the best intentions, it’s easy to make mistakes when it comes to sunscreen. Here are a few common pitfalls to avoid:

• Not applying enough sunscreen.
• Forgetting to reapply.
• Missing often-overlooked spots like the ears and back of the neck.
• Relying on makeup with SPF as your sole sun protection.
• Using expired sunscreen.

Check the expiration date on your sunscreen and replace it if it’s past its prime. Sunscreen loses its effectiveness over time, so it’s important to use a fresh bottle each summer.

The Future of Sunscreen: Predictions and Innovations

The world of sunscreen is always evolving. I predict we’ll see more innovations in the coming years, like edible sunscreen and sunscreen pills. But for now, these are still in the experimental stages. Stick with tried-and-true topical sunscreens for the best protection.

Another exciting development is the rise of reef-safe sunscreens. Traditional chemical sunscreens can harm coral reefs and marine life. Reef-safe sunscreens are formulated without these harmful ingredients, making them a more environmentally friendly choice. I’m seeing more and more brands adopting reef-safe formulas, which is a great step forward.

Embrace the Sun, But Protect Your Skin

Summer is a time to enjoy the outdoors, soak up the sun, and make lasting memories. But it’s also a time to be mindful of your skin’s health. By following the best sunscreen practices, you can protect your skin and enjoy the summer worry-free.

Remember, sun protection is not just about avoiding sunburn. It’s about preventing long-term skin damage, premature aging, and skin cancer. So, slather on that sunscreen, wear your protective clothing, and enjoy the summer responsibly.
