Our Mineral Sunscreens Are Making Modern Waves – Here’s Why

Some sunscreens are more equal than others. Chemical sunscreens absorb the sun’s damaging ultraviolet (UV) rays, while mineral sunscreen - also known as physical sunscreen - reflects UV rays away from your skin. Maybe you already know that mineral sunscreen is a better option for the environment? Perhaps you preach the problems with chemical sunscreen on the beach. Or can even roll the names of harmful chemical filters off your tongue. However, there’s actually a grey area with some mineral sunscreens too, and not just the notorious chalky sheen some leave behind.

Le Rub believes knowledge is power, which enables us to make positive choices for our skin, health and planet. We do things differently to all chemical and most mineral sunscreens. Different in a dazzling way. We considered every grumble aimed at traditional mineral sunscreen, and came up with the perfect formulas for everybody and the ecosystem. 


 

Reef-Safe Ingredients Only

Le Rub uses non-nanotized zinc oxide only, which is the most coral-friendly active sunscreen ingredient available. Most mineral sunscreens contain nano particles, which are less than 100 nanometers. These can slip into our skin, bloodstream and seas, to be ingested by aquatic wildlife. Non-nano zinc oxide has never been found to enter the bloodstream, and so has never been harmful for our health.

 

What’s Else Is Great About Non-Nano Zinc Oxide?

Non-nano zinc oxide sits on the skin’s surface, and acts as a barrier between you and the sun’s damaging ultraviolet rays. Unlike synthetic ingredients and some chemical filters, non-nano zinc-oxide is suitable for those with sensitive skin or skin conditions such as rosacea, eczema and acne. All Le Rub formulas have been dermatologically - and flawlessly – tested on all skin types from very fair to very dark skins.

 

What’s The Issue With Chemical Sunscreen Ingredients Then?


Never did you any harm right? Chemical sunscreen is in fact, a multi-pronged problem. Beginning with basics, for a chemical sunscreen to even work properly it needs time to bind with skin. This takes between 20 and 30 minutes, and we always remember to apply sunscreen half an hour before going in the sun don’t we?

Chemical sunscreen works by absorbing the sun’s UV rays into the product, which might sound helpful, but some chemical filters have been found to penetrate into the skin and blood stream. That’s a cause for concern, due to countless chemical ingredients included to provide broad-spectrum coverage from UV rays. Oh – and some of them are banned for their toxicity in coastal areas. There’s also a prevalence of preservatives and dyes entering the body and irritable fragrances seeping into the skin. Not to mention the seas …

 

The Environmental Effect of Chemical Sunscreen

That’s right, every time you spritz sunscreen at the beach, the excess ends up in the sand that sails off to sea. Chemical sunscreens also wash off your skin and enter waterways, with catastrophic results for the environment. Recent studies suggest that certain chemical filters are hormone disruptors and a major threat to marine life and corals. Ingredients have been found to kill developing coral, and bleach (or genetically damage) existing coral. Hawaii and Key West Florida (areas without a high turnover of water) have banned the ingredients octinoxate and oxybenzone, since 2021. Palau, in the Pacific, forbids banned ‘reef-toxic’ sunscreens containing one of any ten prohibited ingredients, and parts of Mexico require ‘reef-safe’ sunscreen too.

 

What Is Wrong With Some Mineral Sunscreens?

Unfortunately, not all mineral sunscreens are reef-safe. Some sun-screening formulas now combine zinc oxide with titanium dioxide and chemical filters – as if it’s a good thing. It’s really not. Some chemical filters can aggravate acne-prone or sensitive skin. To repeat, Le Rub does things differently. We only do silky-smooth formulas. Every product is plumped with premium skin-replenishing ingredients, such as hydrating hyaluronic acid. Unlike some chemical filters and synthetic ingredients, all of our high-quality ingredients are non-irritating and designed for daily wear. And a reminder, non-nano zinc oxide has never been found to enter the bloodstream.

The Mask

What about that uncomfortable and infamous layer of white cast caused by mineral sunscreens? Le Rub uses high quality zinc dispersed alongside other premium ingredients resulting in our silky-smooth formulas. So no sticky feel or white cast. Just powerful and invisible sunscreen.

 

The Vitamin D Dilemma

By blocking UV rays, sunscreen also blocks our road to the bone-strengthening vitamin D. Le Rub’s Everyday Sunscreen stimulates vitamin D production in the body by including Grape seed ferment extract. It’s a fat-soluble vitamin with antioxidant and skin-soothing benefits for the skin. Clinical tests have shown that this wonder ingredient stimulates the Vitamin D receptor (VDR), allowing the body to respond to vitamin D.
