Invisible Sun Protection for All

by Amelia Glynn March 02, 2020

Sunscreen is hands down the most important part of your daily skincare routine to help prevent premature aging, and our new mineral formula is a gamechanger. Squalane + Zinc Sheer Mineral Sunscreen is super safe (100% non-nano zinc oxide is good for your complexion and the environment), blends into all skin tones without a trace, guaranteed, and is designed for daily wear; you can even swap it for your regular moisturizer.

 Here are answers to the top 5 questions you’re asking about our latest launch:

  1. Why non-nano zinc oxide?

Zinc oxide is the most effective broad-spectrum, physical sun protector available, blocking both UVA (think A for Aging) and UVB (think B for Burn) rays. It’s also gentle and anti-inflammatory, making it a great choice for people with sensitive skin, rosacea, and acne. Non-nano formulas are less likely to be absorbed into the bloodstream or harm reefs or other aquatic life.

  1. Is there a difference between mineral and chemical sunscreen?

Yes. Mineral (a.k.a. physical) sunscreen sits on top of the skin’s surface to create a protective, reflective barrier against UV rays, like tiny mirrors. Unlike chemical sunscreen, it doesn’t degrade or lose efficacy when exposed to the sun. Chemical sunscreen acts more like a sponge, absorbing UV rays, converting them into heat and then releasing the heat from the skin. Chemical sunscreen ingredients can sometimes be irritating to sensitive skin. 

  1. Why did you choose SPF 30?

The Sun Protection Factor (SPF) measures a product’s ability to protect your skin from UVB rays. It’s not meant to determine how long you can stay in the sun without getting burned. Most dermatologists recommend SPF 30 since higher SPFs don’t provide much more sun protection. For example, while SPF 30 sunscreen protects against 97% of the sun’s burning rays, SPF 50 only moves the needle to 98%.

  1. Do I need to wear sunscreen on cloudy days?

UVA sun damage causes about 90% of visible skin aging. While it’s tempting to skip your sunscreen step when skies are grey, clouds only block about 20% of all UV rays so your skin is still exposed to the sun’s harsh effects. Daily sunscreen wear is definitely your best bet for preventing premature aging.

  1. How much sunscreen should I be using?

The squalane in our ultra-hydrating formula creates the perfect glide for easy and fast application. About 1-2 teaspoons are all you need for your face, neck, and chest. Just be sure to reapply every two hours for consistent sun protection.

As a former journalist, I’ve written about everything from architecture and design to fashion and health. While researching ways we can all live healthier lives, I didn’t always make the connection between how what we put on the outside of our bodies can affect the way we feel on the inside. I am a recovering product junkie who never shied away from trying a new facemask or serum, until I learned how to read labels and understand ingredients. Now, I only use the cleanest products available—on my skin and in my home. I was thrilled to discover Biossance and join its mission of setting new clean standards for the entire beauty industry. Clean beauty really can do it all. (The Lactic Acid Resurfacing Night Serum is powerful proof—seriously, whoa.)

How Our Sustainable Squalane Saves Millions of Sharks

We’re here to provide clean beauty that’s better for you and the planet. Our sustainable star ingredient, squalane, is nature’s best moisturizer—it’s a powerfully effective head-to-toe hydrator—but its sister, squalene, has a complex sourcing story.  Our scientists were determined to create a clean, sustainable and ethical squalene alternative. They discovered a way to bioengineer this mega-moisturizer as safely and effectively as the body does—we call it squalane. It’s made from sugarcane, a renewable resource, saving millions of sharks every year.
