How Does Waterproof Sunscreen Work?


If you're looking for a sunscreen that can keep up with your active lifestyle, you'll want to check out waterproof sunscreens. These formulas are designed to stay put even when you're sweating or swimming. 

But how do they work? And are they really as effective as traditional sunscreens? In this article, we'll take a closer look at waterproof sunscreens and answer all of your questions!

What is waterproof sunscreen?

As the name suggests, waterproof sunscreen is a type of sunscreen that is resistant to water. Unlike traditional sunscreens, which can wash off easily with sweat or water, waterproof sunscreen is designed to stay put. This makes it an ideal choice for activities like swimming or sweating.

However, FDA regulations state that no sunscreen can be truly "waterproof" or "sweatproof." Instead, sunscreens can only be labeled as "water-resistant" if they've been proven to maintain their SPF for 40 or 80 minutes after being submerged in water. 

So, if you're looking for a sunscreen that will stay put during your next beach day or pool party, be sure to choose one that is labeled as "water-resistant."

How does waterproof sunscreen work?

Waterproof sunscreen works by creating a barrier on your skin that water can't penetrate. This barrier is typically made of oil, which helps to repel water and keep the sunscreen from washing off.

In addition to oil, waterproof sunscreens also contain ingredients like waxes and silicones, which help to create an even more water-resistant barrier. And, of course, like all sunscreens, waterproof formulas also contain active ingredients such as zinc oxide and titanium dioxide, which work to reflect or absorb UV rays.

In addition to creating a barrier, waterproof sunscreens also contain ingredients that help them adhere to the skin. These ingredients, called binding agents, help to create a stronger bond between the sunscreen and the skin. This ensures that the sunscreen won't rub off easily, even when you're sweating or swimming.

What are the different types of waterproof sunscreen?

There are two main types of waterproof sunscreen: chemical and physical.

Chemical sunscreens work by absorbing the sun's rays and converting them into heat, which is then released from the skin. Physical sunscreens work by reflecting and scattering the sun's rays away from the skin.

Both types of sunscreen can be effective at protecting your skin from the sun. However, physical sunscreens tend to be more water-resistant than chemical sunscreens. This is because the active ingredients in physical sunscreens (like zinc oxide and titanium dioxide) are not as easily washed off by water.

Does waterproof sunscreen offer the same level of sun protection?

Yes, waterproof sunscreen can offer the same level of sun protection as traditional sunscreen. However, it's important to keep in mind that no sunscreen is completely waterproof. So, if you're going to be sweating, be sure to reapply your sunscreen every two hours (or more often if you're swimming).

In addition, remember that sunscreen should only be one part of your sun protection strategy. Be sure to also seek shade, wear protective clothing, and avoid the sun during peak hours (10 am to 2 pm).

Top 9 tips for wearing waterproof sunscreen

When it comes to wearing waterproof sunscreen, there are a few things you should keep in mind. Here are our top 9 tips:

Tip 1: Your sunscreen should have an SPF of 30 or higher

A sunscreen with an SPF of 30 or higher will provide you with the best protection against the sun's harmful rays. The higher the SPF, the better. An SPF of 15 filters out about 93% of the sun's rays, while an SPF of 30 filters out about 97%.

Also, make sure to choose a sunscreen that is labeled "broad spectrum", as this means that it will protect you from both UVA and UVB rays. 

So, if you are looking for the best possible protection, Australian Gold Plant-Based SPF 50 Lotion is the sunscreen for you.

Tip 2: Apply sunscreen 15 minutes before going outdoors

It is important to apply sunscreen 15 minutes before you go outdoors, as it takes this amount of time for the sunscreen to bind to your skin. If you don't wait 15 minutes, you won't get the full benefit of sunscreen.

Tip 3. Apply sunscreen liberally to all exposed skin

You should apply sunscreen liberally to all exposed skin, including your face, neck, ears, and hands. The most ignored areas are often the peepers and lips, so don't forget those!

Be sure to use enough sunscreen so that it is visible on your skin. An adult should use approximately 1 ounce (enough to fill a shot glass) of sunscreen to cover their entire body.

As there are no particular downsides to applying too much sunscreen, it is better to err on the side of caution and use more rather than less.

Tip 4. Reapply sunscreen every 80 minutes.

Even if you are using waterproof sunscreen, you should reapply it every 80 minutes to ensure that you are getting the full benefit. This is especially important if you are swimming or sweating.

Tip 5. If you use spray sunscreen, apply it in a well-ventilated area

If you use spray sunscreen, be sure to apply it in a well-ventilated area. This is because the spray can be harmful if inhaled. Spray sunscreen allows for a more even application, but be sure to cover all exposed skin thoroughly.

One of the best water-resistant spray sunscreens on the market is the Australian Gold Botanical SPF 70 Natural Spray Sunscreen. Made with natural ingredients, this sunscreen offers a broad spectrum of protection and is water-resistant for up to 80 minutes.

Tip 6. Check the expiration date on your sunscreen

Sunscreen can expire and lose its effectiveness, so it is important to check the expiration date before using it. Most sunscreens have a shelf life of 3 years.

Tip 7. Don't skip the sunscreen on cloudy days

Even on cloudy days, it’s important to wear sunscreen. The sun's rays can still penetrate the clouds and cause damage to your skin. However, the sun's rays are the strongest between 10 am and 2 pm, so it is best to avoid spending prolonged periods of time outdoors during these hours. 

If you must be outside, be sure to seek out shade and wear protective clothing, such as a hat and sunglasses.

Tip 8: Choose a sunscreen that is specifically designed for your face

The skin on your face is much thinner and more delicate than the skin on the rest of your body, so it is important to choose a sunscreen that is specifically designed for use on the face.

Some sunscreens can be quite drying, so it is important to find one that will not leave your skin feeling tight and dry. The Australian Gold Plant-based SPF 50 Face Lotion is a great option, as it contains Aloe Vera and Coconut Oil to help soothe and hydrate the skin.

Tip 9: Store sunscreen in a cool, dry place.

To maintain the effectiveness of your sunscreen, be sure to store it in a cool, dry place. Heat and sunlight can degrade the quality of the sunscreen, so it is best to keep it in a dark, cool place.
