The sun is a great source of vitamin D, but it can also be harmful to your skin. Sunburns and skin cancer are some of the risks associated with prolonged exposure to UV rays. That’s where sunscreen comes in as an essential tool for protecting your skin from these harmful rays. In this post, we will cover everything you need to know about sunscreen- from why it is important, the different types of sunscreen available in the market, how much SPF you should use, and more. We will also touch upon how sunscreen affects the environment and what to look for while selecting eco-friendly options. So read on and get ready to protect your skin from any harm caused by those harmful rays.
Why is sunscreen important?
Using sunscreen is crucial to shield your skin from harmful UV rays responsible for sunburn, early aging, and skin cancer. Regular use can also prevent dark spots and hyperpigmentation. Remember to apply it on cloudy days too, and pick one with broad-spectrum protection and an SPF of 30 or more for optimal coverage.
Understanding SPF
To protect your skin from the harmful effects of UV radiation, it’s essential to understand the importance of sunscreen. Sun Protection Factor (SPF) measures a product’s ability to shield your skin from UVB radiation that causes sunburn and increases the risk of skin cancer. For optimal daily protection against UV exposure in the United States, dermatologists recommend broad-spectrum sunscreen products with at least SPF 30. Remember that higher SPF doesn’t necessarily mean better protection; other factors like reapplication frequency play a crucial role.
Different types of sunscreen
Physical, chemical, and combination are the three main types of sunscreen available in the market. Physical sunscreen has mineral-based ingredients such as zinc oxide or titanium dioxide that reflect the sun’s rays off the skin. In contrast, chemical sunscreen has organic compounds that absorb UV radiation and convert it into heat. Combination sunscreen is a mixture of both physical and chemical ingredients to provide broad-spectrum protection. It’s essential to choose a broad-spectrum SPF with an SPF of at least 30 for maximum protection against UVB (skin burn) and UVA (ageing). Zinc oxide and titanium dioxide are common active ingredients in physical sunscreens, while avobenzone is a common active ingredient in chemical sunscreens. We’d recommend a physical sunscreen if you want to avoid chemicals, and especially if you’re going to use it on your face as chemical SPF’s can burn your eyes all day. Some of our favorites are ISDIN’s Eryfotona Ageless & Actinica, both contain zinc. If you’re going for an all over option, check out EltaMD’s Sport, which is an SPF 50 and water-resistant.
Water-resistant sunscreens
When spending extended periods outdoors, water-resistant sunscreens are an excellent choice to keep your skin protected from harmful UV radiation. Whether you’re taking a dip in the ocean or working up a sweat on the tennis court, these sunscreens will remain effective. Remember to reapply often and select the appropriate water-resistant level based on your activity level. EltaMD’s Sport is made with beeswax, so instead of dripping into your eyes, your SPF will stay put even during the most strenuous of activities.
Does higher SPF mean better protection?
SPF only measures UVB protection, not UVA. A higher SPF doesn’t necessarily mean better protection: SPF 30 blocks about 97% of UVB rays while SPF 50 blocks about 98%. Choose a broad-spectrum sunscreen that protects against both UVA and UVB, and consider factors like application and water resistance.
Best practices for applying sunscreen
To adequately protect your skin from harmful UV radiation, it’s essential to follow best practices when using sunscreen. For the body, apply about two tablespoons (or a shot glass) of broad-spectrum sunscreen at least 15-30 minutes before sun exposure and reapply every two hours or after swimming or sweating. Be sure to get the hands and feet. For the face, you should be using at least a nickel size dollop. Be sure to pay attention to high-risk areas such as the nose, ears, and shoulders.
Common sunscreen myths
- Contrary to popular belief, you need to use sunscreen even on cloudy days because UV rays can penetrate through clouds.
- A higher SPF doesn’t necessarily mean better protection against UV radiation.
- Oxybenzone present in some sunscreens can harm coral reefs and other aquatic life forms.
- Using a base tan does not provide adequate protection against harmful UV rays and increases the risk of skin cancer.
- Make sure you choose broad-spectrum sunscreen with appropriate SPF based on your skin type and reapply every two hours.
Sunscreens for different skin types
Choosing the right sunscreen for your specific skin type is essential in ensuring maximum sun protection. Oily-skinned individuals should opt for oil-free and non-comedogenic formulas that prevent breakouts and control shine. We love EltaMD’s UV Clear, which is specifically for acne-prone skin. Dry-skinned people should look for moisturizing formulations containing ingredients such as hyaluronic acid or squalene to keep their skin hydrated. UV Restore is for all skin-types, comes in tinted and non-tinted, and restores skin’s natural moisture and suppleness. Those with sensitive skin require fragrance-free and hypoallergenic sunscreens that are gentle on their delicate complexion. Combination-skinned people benefit from lightweight and non-greasy formulations that cater to both dry and oily areas. UV Sheer is your go-to for combination skin, hosting a lightweight formula that is silky to the touch and is compatible with all skin tones, so you’re not left with a white cast.
Sunscreen and the environment
To ensure our skin stays safe from harmful UV rays while keeping our environment protected, we must choose our sunscreen wisely. When selecting a product, look for mineral-based sunscreens with natural ingredients like zinc oxide and titanium dioxide. These options are not only better for the planet but also provide excellent protection against UVA and UVB rays. Avoid using spray-on sunscreens as they release harmful aerosols into the air; instead, opt for reef-safe alternatives that don’t contain oxybenzone or octinoxate.
Sunscreen is a crucial component of any skincare routine, protecting your skin from harmful rays that can lead to sunburn, premature aging, and even skin cancer. With the right information, choosing the best sunscreen for you becomes easy. Take note of your skin type and the occasion before you buy a sunscreen product. Sunscreens that are water-resistant and have an SPF of at least 30 are ideal for daily use. Always be mindful of the environment when applying sunscreen and choose products that are reef-friendly. Lastly, don’t forget to schedule your annual skin exam with us so we can make sure your SPF is doing it’s job!
