The best sunscreen: choosing the right sun protection

The best sunscreen is the one you use liberally and according to label instructions. Know what to look for on sunscreen labels and how to maximize your sun protection.

What are the best ways to protect yourself from the sun?

Focus on the big picture when it comes to sun protection. For example:

– Avoid the sun during peak hours. In general, it is between 10 hours and 16 hours. Water, snow, sand and concrete reflect light and increase the risk of sunburn.

– Wear protective clothing against the sun. This includes pants, long-sleeved shirts, sunglasses, and hats.

– Use sunscreen. Look for broad-spectrum, water-resistant coverage with a UV rating of at least 30. Apply sunscreen liberally and reapply every two hours, or more often if you swim or sweat.

What does sunscreen do broad spectrum?

There are two types of UV rays that can harm your skin: UVA and UVB. A broad-spectrum sunscreen protects you against both types of rays.

UVA rays can prematurely age your skin and cause wrinkles and age spots. UVB rays can burn your skin. Too much UVA or UVB exposure can cause skin cancer. The best sunscreen provides protection against UV rays.

What sun factor do you need?

The sun protection factor solar (SPI) is a measure of the effectiveness of sun protection against UVB rays. (UVA protection is not rated.) Manufacturers calculate sun protection factor based on how long it takes skin treated with sunscreen to get sunburned, compared to skin without. sunscreen.

Experts recommend using sunscreen with an SPF of at least 30. Sunscreens with an SPI greater than 16 offer only a small increase in UV protection . High SPIs have the same lifespan as low SPIs.

Often sunscreen is not applied thoroughly or thick enough, and it can be washed off while swimming or sweating. As a result, sun protection may be less effective than the SPF suggests.

What does a water-resistant sunscreen do?

The term “water resistant” means that the IPS is maintained up to 30 minutes in water. Highly water resistant means that the IPS is maintained for 80 minutes in water.

What should I know about sunscreen ingredients?

Sunscreens contain filters that reflect or absorb UV rays. There are two main types of filters:

– Organic filters

in principle organic filters absorb radiation UV and convert it to a small amount of heat. Examples are cinnamates, salicylates and benzophenones.

– Inorganic

Inorganic filters reflect and scatter UV radiation. These are, for example, titanium dioxide and zinc oxide. Inorganic sunscreens are generally less irritating to the skin.

Sunscreens may also contain or be combined with:

– Repellent for insects

Experts recommend using sunscreen products and insect repellents separately. Sun protection should be applied generously and often, while insect repellents should be used sparingly and less frequently.

– Cosmetics

Some moisturisers, make-up and aftershaves contain sunscreen. Although convenient, these products should be reapplied regularly to continue providing protection.

Should I use spray sunscreen or lotion?

Look at the pros and cons of different applications, including:

– Creams

If you have dry skin, you may prefer a cream, especially for the face.

– Lotions

They are often preferred for application on large surfaces. Lotions tend to be thinner and less greasy than creams.

– Spray

Sprays are easy to apply to children. Since it’s hard to know how far you’re applying it, spray a generous, even coat. To avoid inhalation of product, do not spray near face or mouth. Check wind direction before spraying.

What else should I know about sunscreen?

When using sunscreen :

– Apply a generous amount of sunscreen to dry skin 15 minutes before going outdoors.

– Use sunscreen on all areas of skin that will be exposed to the sun, such as the neck, tops of the feet, the ears and the top of the head. Apply to your lips a lip balm or lipstick with an SPI of at least 30 .

– Since UV rays can pass through clouds, use sunscreen even on cloudy days.

– Check the expiration date of the sunscreen.

– Avoid using sunscreen on children under 6 months. Instead, try to limit sun exposure.

Use sunscreen year-round, but don’t let any product lure you into a false sense of security about sun exposure. A combination of shade, clothing, sunscreen and common sense is your best bet
