What is RSC? A Talk Story with Eric on the Truth About Real Sun Cover Sunscreen

What is RSC Sunscreen? An All Natural and Effective Sun Protection

RSC (Real Sun Cover) is a line of natural, zinc oxide-based sunscreens that prioritize safety and environmental friendliness. Unlike many conventional sunscreens that rely on potentially harmful petroleum-based chemicals, RSC sunscreens use only non-nano zinc oxide as the active ingredient, providing broad-spectrum UV protection without the risks associated with nanoparticles or synthetic UV filters.

The RSC sunscreen formulas are simple yet effective, consisting of natural ingredients like coconut oil, beeswax, and organic cocoa powder (which gives the sticks their brown color and antioxidant properties). These ingredients are already present in our diets and pose no harm to our bodies or the environment, making RSC sunscreens a truly reef-safe option. With an SPF of around 32 (or 97% UV protection), RSC's UV formula offers ample protection against both UVA and UVB rays, without the need for excessive SPF values that often involve questionable ingredients or testing methods.

To better understand the science and philosophy behind RSC sunscreens, let's dive into a talk story with Eric, the man who formulated the RSC sunscreen. 

The Truth About Real Sun Cover Sunscreen: An Eric Talk Story 

In this talk story, Eric shares his expertise on sunscreen and why zinc oxide is the best active ingredient for protecting your skin. According to Eric, zinc oxide is a naturally occurring mineral that offers the broadest spectral absorbance of any FDA-approved sunscreen. It's inert, doesn't degrade, and won't cause free radical damage to your skin.

Petroleum-Based Sunscreens: Harmful to Your Body and the Environment

Eric warns against the dangers of petroleum-based sunscreen ingredients, which are fundamentally toxic and can have side effects. He explains that these chemicals mimic estrogen in our bodies, are benzene-coated hydrocarbons (known to be toxic), and can cause DNA damage. Worse, they don't biodegrade in the environment, harming ecosystems and marine life.

Real Sun Cover's Natural Formula

Real Sun Cover's sunscreen formula is made from natural ingredients like coconut oil, beeswax, and organic cocoa powder (which gives the stick its brown color and antioxidant properties). Eric emphasizes that these ingredients are already present in our diets and pose no harm to our bodies or the environment.

Real Sun Cover's UV formula contains 25% non-nano zinc oxide, which provides an SPF of around 32 (or 97% UV protection). Eric explains that anything above SPF 30 is mostly a marketing gimmick, as the additional protection is minimal compared to the increased chemical exposure.

Nanoparticles: Potential Risks

Eric discusses the potential risks of nanoparticles, which are particles smaller than 100 nanometers in diameter. While some companies use nanoparticle zinc oxide for better skin coverage, Eric avoids it due to the lack of safety data and potential environmental issues.

Eric emphasizes that Real Sun Cover's sunscreen is safe because it uses larger, micronized zinc oxide particles (100-1000 nanometers) that have been around for a long time and don't pose the same risks as nanoparticles. He also avoids using unapproved UV-active ingredients or anti-inflammatories, which can game the SPF testing system and provide false protection.

Understanding Skin Cancer and UV Damage

Eric explains that skin cancer is a probability game, where the more UV damage and free radicals your skin cells accumulate, the higher the risk of cancer. He stresses the importance of minimizing this damage by using effective sunscreen and avoiding excessive sun exposure.

SPF Testing and UV Protection

Eric discusses the flaws in the SPF testing system, which relies on visual inspection of redness on the skin. He advocates for reporting UV protection as a percentage, as SPF values can be misleading. For example, an SPF 30 provides 97.3% UV absorption, while an SPF 50 offers only slightly more protection at 98%.

Applying and Reapplying Real Sun Cover

One of the advantages of Real Sun Cover's stick formula is its persistence on the skin. As long as you can see it, you know it's providing the rated SPF protection. Eric explains that reapplication is necessary to maintain the SPF level, but it doesn't provide additional protection beyond the rated value.

Reef-Safe Sunscreen

Eric addresses the issue of "reef-safe" sunscreens, which often ban specific chemicals like oxybenzone but still contain other harmful petroleum-based ingredients. He argues that zinc oxide and titanium dioxide are the only truly reef-safe options, as they won't cause the same damage as petrochemicals

Real Sun Cover Sunscreen



I have been using RSC for over 2 years now, works great, better than many others I had been using. I don’t burn like I used to and it’s organic, doesn’t sting if it gets in your eyes. Remember to shake the tube before applying and re-apply after 2 hours. Mahalo!” - David L. Honolulu

“I’ve been using another popular product for a few years even before I was surfing. I used it frequently when I went to the beach with my friends but always had eye irritation. I thought the price was reasonable, so I kept using it until I met Brett and Dave from Hawaiian South Shore. They introduced 100% natural sunscreen that protects both your skin and the ocean. I was reluctant to purchase it right away because of the price and the size of the sunscreen (small). After I began surfing, I needed a type of sunscreen that couldn’t wash off easily. So, I decided to give it a try. After two months of usage, I regret not buying this product earlier. Even with a small amount of either stick or creme type, it’s good enough for you to stay out in the water for 2-3 hours. The best thing about this sunscreen is that you will NOT get an eye irritation. This just tells me that this sunscreen is 100% natural and a trustworthy product. I’ve been recommending this product to my friends from S. Korea when they visit me, and they love it too. It’s very portable and easy to use. One thing though, I use a makeup removal oil to remove the sunscreen off my face completely. I definitely recommend this sunscreen to anyone whether you surf or not, because this product protects not only your skin but also our environment.” - David C.
