It's still summer in California!

Updated: Oct 17, 2022

Finally! After four years of intensive research and development, we are excited to announce the launch of the Coral Sure Sunscreen product line.

Coral Sure is a mineral based sunscreen that is reef safe and non-toxic to marine life - which means that it is kinder to you and kinder to the environment. Developed and formulated in sunny southern California, it's been a very long time in the making since we had the idea... no, the compulsion to act after seeing so many sunscreens on the market that claimed to be 'reef safe' or 'reef friendly' but actually included chemicals known to harm marine life and contribute to coral bleaching events.

With amazing natural humectants, skin loving emollients, and antioxidants, Coral Sure Sunscreen can be used in place of your regular moisturizer, or even over it. And since it is harmless to the environment, coral and marine life, it's great to use every day as part of your regular skin care regime to protect the whole family.

Coral Sure Sunscreen utilizes non-nano technology to create a formula with moisturizing qualities and is derived from responsibly sourced organic ingredients. It is broad spectrum SPF 35, water resistant, and free from harmful chemicals such as oxybenzone, avobenzone, octinoxate, and parabens.

Here's what people are saying about it:

“I have been looking for a non-chemical sunscreen that moisturizes and protects for a very long time. All of the other mineral sunscreens I have tried felt too pasty and were hard to rub in. Coral Sure rubs in easily and doesn't leave me looking all pasty-white.”

Its mission is to manufacture a sunscreen that is truly non-toxic to the marine eco-system and ​will afford the user the highest standard of skin protection from the sun's harmful UV rays.
