Sunscreen FAQs: Protecting Your Skin From UV Rays

Sunscreen plays a vital role in shielding your skin from harmful UV rays and is essential for adults and children alike. With so many products on the market, knowing which sunscreen is best for you and your family can be challenging. To help you make an informed decision, we at Cascade Eye & Skin Centers have answered some of the most common questions regarding sunscreen. Whether you’re looking to protect yourself or your child, these FAQs can help you understand everything you need to know about sunscreen.

Who Needs Sunscreen?

Contrary to popular belief, sunscreen is not just for beachgoers. UV rays can affect anyone, regardless of age, gender, or skin color. Too much sun exposure may cause skin damage, premature aging, and increase the risk of skin cancer. Therefore, it is crucial to protect your skin with sunscreen regardless of who you are.

What Sunscreen is the Best to Use?

When selecting a sunscreen, ensure it offers broad-spectrum protection. This means it shields your skin from both UVA and UVB rays. While UVA rays penetrate deep into the skin and contribute to premature aging, UVB rays are responsible for sunburn. Additionally, you should also choose a sunscreen with a SPF 30+.

SPF stands for sun protection factor and is a general indication of how long you can be in the sun without burning. SPF 30, for example, allows you to stay in the sun 30 times longer than you would without sunscreen. However, no sunscreen can completely block UV rays, so reapplication is crucial. For those who engage in water activities or tend to sweat, water-resistant sunscreen is a must. Keep in mind that water-resistant doesn’t mean waterproof. Reapply after swimming, sweating, or drying off with a towel.

When is Sunscreen Necessary?

Sunscreen should be a part of your daily skincare routine. UV rays are present even on cloudy or cold days. Snow, sand, and water can also reflect UV rays, increasing exposure. For instance, snow may reflect up to 80% of UV radiation. UV rays are most intense between 10 a.m. and 4 p.m. If possible, avoid direct sun exposure during these hours. If you must be outside, wearing sunscreen, sunglasses, and protective clothing is essential.

How Much Sunscreen Should I Use?

A common mistake is not using enough sunscreen. Before going outside, apply a generous amount of sunscreen to all exposed areas. Make sure to cover often-missed spots like the ears, neck, and feet. Typically, an adult would use one ounce of sunscreen to cover their entire body. Don’t forget to reapply sunscreen every two hours to ensure your skin is fully protected.

How Can I Protect My Baby or Toddler from the Sun?

The delicate skin of babies and toddlers is especially vulnerable to the harmful effects of UV rays. As a parent, taking extra precautions to shield your little ones from the sun is crucial. For infants under six months, it’s best to avoid sun exposure altogether. For older babies and toddlers, opt for a broad-spectrum, water-resistant sunscreen with an SPF of at least 30. Physical sunscreens are preferable as they are less likely to irritate sensitive skin. If your child is going to the beach or pool, consider purchasing a rashguard to cover their arms and torso.

Does Sunscreen Expire?

Like many other skincare products, sunscreen does have an expiration date. Using it past this date can have consequences. Sunscreen is formulated with active ingredients that protect your skin from harmful UV rays. Over time, these ingredients can break down and lose their effectiveness. Most sunscreens have a shelf life of about three years, but this may vary depending on the product and storage conditions.

Always check the packaging for an expiration date. If there isn’t one, write the purchase date on the bottle and aim to use it within three years. Furthermore, pay attention to changes in the product’s smell, texture, or color, as these may be signs the sunscreen has gone bad. To ensure your sunscreen stays effective up to its expiration date, store it in a cool, dry place. Avoid leaving it in direct sunlight or a hot car, as heat can accelerate the breakdown of active ingredients.

Chemical vs. Physical Sunscreens

Chemical sunscreens contain organic compounds such as avobenzone, octocrylene, and oxybenzone, which absorb UV rays and convert them into heat that is released from the skin. They are generally easier to apply and less noticeable on the skin, making them a popular choice for daily wear. However, they can sometimes irritate sensitive skin.

On the other hand, physical sunscreens use minerals like zinc oxide or titanium dioxide to reflect UV rays away from the skin. They sit on the skin’s surface and are effective immediately upon application. Physical sunscreens are often considered more suitable for sensitive skin and have a lower environmental impact. When choosing between chemical and physical sunscreens, consider factors such as your skin type, preferences, and environmental considerations to make the best choice for your sun protection needs.

How Do I Treat a Sunburn?

Got a sunburn? Here’s how to alleviate the pain and support healing:

  • Cool down: Take a cool bath or shower to soothe the skin. You can also use cold compresses on the affected area.
  • Moisturize: Apply a moisturizer or lotion with aloe vera or soy to the sunburned skin to keep it hydrated.
  • Stay hydrated: Drink plenty of water to help your body recover.
  • Pain relief: Take over-the-counter pain relievers like ibuprofen or aspirin to reduce inflammation and relieve pain.
  • Avoid sun exposure: Keep the sunburned area covered and avoid further sun exposure until your skin heals.
  • Don’t pop blisters: If blisters form, don’t pop them. They’re your body’s way of healing the skin.

Remember, sunburn can damage your skin and increase your risk of skin cancer. Always take precautions to protect your skin from the sun.
